The Design-Code Roundtrip That Isn't — Jonathan Gordon, ReWeaver AI

Hello everyone. I'm Jonathan Gordon. I'm Hello everyone. I'm Jonathan Gordon. I'm a founder of Reweaver AAI, a new a founder of Reweaver AAI, a new a founder of Reweaver AAI, a new company, you know, on the scene, let's company, you know, on the scene, let's company, you know, on the scene, let's say. I want to share one thing with all say. I want to share one thing with all say. I want to share one thing with all of you that was really fascinating. So, of you that was really fascinating. So, of you that was really fascinating. So, I I plugged in my laptop and I realized I I plugged in my laptop and I realized I I plugged in my laptop and I realized I had to mirror. So, I no longer have my I had to mirror. So, I no longer have my I had to mirror. So, I no longer have my speaker notes. So, I went into Claude speaker notes. So, I went into Claude speaker notes. So, I went into Claude and I said, "Can you extract my speaker and I said, "Can you extract my speaker and I said, "Can you extract my speaker notes from my slide deck, please?" And I notes from my slide deck, please?" And I notes from my slide deck, please?" And I had my speaker notes now. had my speaker notes now. had my speaker notes now. I love AI. I love AI. I love AI. The suspense was killing me. I was The suspense was killing me. I was The suspense was killing me. I was talking to Claude talking to Claude talking to Claude now. Who knows if it got it right. I now. Who knows if it got it right. I now. Who knows if it got it right. I don't know. Whatever. Um, so I also don't know. Whatever. Um, so I also don't know. Whatever. Um, so I also realized that my title slide buried the realized that my title slide buried the realized that my title slide buried the lead. I shouldn't have put it up. Um, lead. I shouldn't have put it up. Um, lead. I shouldn't have put it up. Um, but nonetheless, let's play with this. but nonetheless, let's play with this. but nonetheless, let's play with this. So, uh, yeah, my name is Jonathan. Um, So, uh, yeah, my name is Jonathan. Um, So, uh, yeah, my name is Jonathan. Um, I'm here to talk to you about the design I'm here to talk to you about the design I'm here to talk to you about the design code roundtrip that isn't. code roundtrip that isn't. code roundtrip that isn't. And I guess probably the best thing to And I guess probably the best thing to And I guess probably the best thing to do first is to explain what I think a do first is to explain what I think a do first is to explain what I think a design code roundtrip should be. Um the design code roundtrip should be. Um the design code roundtrip should be. Um the design code roundtrip is a full loop design code roundtrip is a full loop design code roundtrip is a full loop between design and engineering in both between design and engineering in both between design and engineering in both directions without any loss of fidelity directions without any loss of fidelity directions without any loss of fidelity and with a persistent provenence. So it and with a persistent provenence. So it and with a persistent provenence. So it knows exactly where everything came knows exactly where everything came knows exactly where everything came from. You know that perfect dream world from. You know that perfect dream world from. You know that perfect dream world that we live in where there is no drift that we live in where there is no drift that we live in where there is no drift in between the gaps of design and code.

in between the gaps of design and code. in between the gaps of design and code. Um, today's tools, design is amazing. Um, today's tools, design is amazing. Um, today's tools, design is amazing. It's incredible. It's magic. It's I ask It's incredible. It's magic. It's I ask It's incredible. It's magic. It's I ask for something, I get it. It's clickable. for something, I get it. It's clickable. for something, I get it. It's clickable. It's interactive. It's amazing to me. It's interactive. It's amazing to me. It's interactive. It's amazing to me. But nobody really looks at the code But nobody really looks at the code But nobody really looks at the code anymore, it seems. And so, I kind of anymore, it seems. And so, I kind of anymore, it seems. And so, I kind of want to go there. I want to go into that want to go there. I want to go into that want to go there. I want to go into that space. space. space. Whoops. Of course, I have to get my Whoops. Of course, I have to get my Whoops. Of course, I have to get my mouse to the right location. There we mouse to the right location. There we mouse to the right location. There we go. Um, a little bit about me. go. Um, a little bit about me. go. Um, a little bit about me. past 30 plus years um I've been building past 30 plus years um I've been building past 30 plus years um I've been building and designing coding tools developer and designing coding tools developer and designing coding tools developer tools idees at these companies um so tools idees at these companies um so tools idees at these companies um so I've spent a lot of time with as a I've spent a lot of time with as a I've spent a lot of time with as a designer I've spent a lot of time with designer I've spent a lot of time with designer I've spent a lot of time with design and engineering teams trying to design and engineering teams trying to design and engineering teams trying to understand understand understand how do we do that handoff well how do we how do we do that handoff well how do we how do we do that handoff well how do we hand off from design to code how do we hand off from design to code how do we hand off from design to code how do we get what we wanted to be delivered to get what we wanted to be delivered to get what we wanted to be delivered to the customer um it was never a perfect the customer um it was never a perfect the customer um it was never a perfect science We never got it. We never found science We never got it. We never found science We never got it. We never found that magic sauce that just made that magic sauce that just made that magic sauce that just made everything come together where intent everything come together where intent everything come together where intent matched the outcome.

matched the outcome. matched the outcome. Um, but I developed techniques. I Um, but I developed techniques. I Um, but I developed techniques. I negotiated with engineers. I brought negotiated with engineers. I brought negotiated with engineers. I brought them out for drinks. I made them my them out for drinks. I made them my them out for drinks. I made them my friends. Um, I got things delivered to friends. Um, I got things delivered to friends. Um, I got things delivered to customers. customers. customers. But the the loop was never closed. Um, But the the loop was never closed. Um, But the the loop was never closed. Um, and it's because our outcomes diverged. and it's because our outcomes diverged. and it's because our outcomes diverged. engineering had one set of requirements, engineering had one set of requirements, engineering had one set of requirements, technical constraints, design had a technical constraints, design had a technical constraints, design had a vision for the future, a new rebranding, vision for the future, a new rebranding, vision for the future, a new rebranding, whatever. So, this has existed, you whatever. So, this has existed, you whatever. So, this has existed, you know, dare I say, for decades. know, dare I say, for decades. know, dare I say, for decades. Um, then along comes AI Um, then along comes AI Um, then along comes AI and LLM and prompting ourself into a and LLM and prompting ourself into a and LLM and prompting ourself into a fully running application. In a sense, fully running application. In a sense, fully running application. In a sense, now we have one intelligence that now we have one intelligence that now we have one intelligence that understands design intent and the same understands design intent and the same understands design intent and the same intel in intelligence can write code. So intel in intelligence can write code. So intel in intelligence can write code. So I thought to myself, oh my god, I think I thought to myself, oh my god, I think I thought to myself, oh my god, I think we might be able to close this loop. At we might be able to close this loop. At we might be able to close this loop. At the speed of inference, we could close the speed of inference, we could close the speed of inference, we could close this loop. And so I was curious. Um, I'm this loop. And so I was curious. Um, I'm this loop. And so I was curious. Um, I'm curious by nature. So I went all in.

curious by nature. So I went all in. curious by nature. So I went all in. That's my GitHub before vibe coding That's my GitHub before vibe coding That's my GitHub before vibe coding happened on the left on on my left on happened on the left on on my left on happened on the left on on my left on your whatever. Um then after so I think your whatever. Um then after so I think your whatever. Um then after so I think everybody probably gets a sense of what everybody probably gets a sense of what everybody probably gets a sense of what my life was like from April 2025. And if my life was like from April 2025. And if my life was like from April 2025. And if you want to scroll till today it's it's you want to scroll till today it's it's you want to scroll till today it's it's even more so. Um, I got this email from even more so. Um, I got this email from even more so. Um, I got this email from cursor one day that said I was in the cursor one day that said I was in the cursor one day that said I was in the top 0.1% top 0.1% top 0.1% of usage of cursor of usage of cursor of usage of cursor and I thought to myself, I need to spend and I thought to myself, I need to spend and I thought to myself, I need to spend more time outside. Then there was a bill. Um, Then there was a bill. Um, but at the time it was the $20 deal and but at the time it was the $20 deal and but at the time it was the $20 deal and I kind of, you know, monitored, but I kind of, you know, monitored, but I kind of, you know, monitored, but every now and again I'd pay for a little every now and again I'd pay for a little every now and again I'd pay for a little bit more, get another hit. Um, bit more, get another hit. Um, bit more, get another hit. Um, and this was my life vibe coding from and this was my life vibe coding from and this was my life vibe coding from that point in April that point in April that point in April until today. Um, I'm trying to figure until today. Um, I'm trying to figure until today. Um, I'm trying to figure out can I go from design to code? Can I out can I go from design to code? Can I out can I go from design to code? Can I go from code to design? Can I build a go from code to design? Can I build a go from code to design? Can I build a tool to go from design to code and code tool to go from design to code and code tool to go from design to code and code to design a full round trip without any to design a full round trip without any to design a full round trip without any loss of fidelity? That pixel perfect loss of fidelity? That pixel perfect loss of fidelity? That pixel perfect dream that we have. Um, I remember dream that we have. Um, I remember dream that we have. Um, I remember vividly uh one day I was, you know, just vividly uh one day I was, you know, just vividly uh one day I was, you know, just hammering away at the keyboard, just hammering away at the keyboard, just hammering away at the keyboard, just vibing my way. I was really feeling the vibing my way. I was really feeling the vibing my way. I was really feeling the vibe. And, uh, this wall of text was vibe. And, uh, this wall of text was vibe. And, uh, this wall of text was coming by and I was completely ignoring coming by and I was completely ignoring coming by and I was completely ignoring it and code was being written, just

it and code was being written, just it and code was being written, just watching that come by. And I remember watching that come by. And I remember watching that come by. And I remember seeing a statement that was an inner seeing a statement that was an inner seeing a statement that was an inner HTML statement. HTML statement. HTML statement. And I remember from way back when that And I remember from way back when that And I remember from way back when that inter HTML was a security vulnerability inter HTML was a security vulnerability inter HTML was a security vulnerability that people can actually inject into in that people can actually inject into in that people can actually inject into in HTML and I stopped it. I said, "Wait a HTML and I stopped it. I said, "Wait a HTML and I stopped it. I said, "Wait a minute, wait a minute." to my LM, "Wait minute, wait a minute." to my LM, "Wait minute, wait a minute." to my LM, "Wait a minute, what did you just do?" And it a minute, what did you just do?" And it a minute, what did you just do?" And it explained to me what it did and it was explained to me what it did and it was explained to me what it did and it was very proud of itself. And and I said, very proud of itself. And and I said, very proud of itself. And and I said, "Revert that. Do this instead." Blah "Revert that. Do this instead." Blah "Revert that. Do this instead." Blah blah. And I got into this mode of like, blah. And I got into this mode of like, blah. And I got into this mode of like, "Oh, maybe I need to steer this thing a "Oh, maybe I need to steer this thing a "Oh, maybe I need to steer this thing a little bit better. Maybe I can't just go little bit better. Maybe I can't just go little bit better. Maybe I can't just go blindly in. Maybe I need to look at the blindly in. Maybe I need to look at the blindly in. Maybe I need to look at the code now. code now. code now. And I've looked at a lot of code in my And I've looked at a lot of code in my And I've looked at a lot of code in my life. So I went ahead and went in and life. So I went ahead and went in and life. So I went ahead and went in and looked at the code and I Whoops. I'm looked at the code and I Whoops. I'm looked at the code and I Whoops. I'm sorry. I clicked too ahead and I found I sorry. I clicked too ahead and I found I sorry. I clicked too ahead and I found I found issues. And so I went a little bit found issues. And so I went a little bit found issues. And so I went a little bit deeper deeper deeper when the industry started to tell me when the industry started to tell me when the industry started to tell me that they had solved the round trip that they had solved the round trip that they had solved the round trip that you could go a true roundtrip that you could go a true roundtrip that you could go a true roundtrip workflow. You could roundtrip between workflow. You could roundtrip between workflow. You could roundtrip between code and canvas. I think folks in the code and canvas. I think folks in the code and canvas. I think folks in the room might remember back in February, room might remember back in February, room might remember back in February, no slam on anthropic or Figma, there was no slam on anthropic or Figma, there was no slam on anthropic or Figma, there was this demo that showed going from cloud this demo that showed going from cloud this demo that showed going from cloud code into Figma. And it was magic. It code into Figma. And it was magic. It code into Figma. And it was magic. It was incredible. I couldn't believe you was incredible. I couldn't believe you was incredible. I couldn't believe you could build a Figma artboard from a could build a Figma artboard from a could build a Figma artboard from a prompt in Cloud Code. And then I had to prompt in Cloud Code. And then I had to prompt in Cloud Code. And then I had to go deeper and I had to look deeper in go deeper and I had to look deeper in go deeper and I had to look deeper in the same way that I looked at vibe the same way that I looked at vibe the same way that I looked at vibe coding. Like, is this real? Is the hype coding. Like, is this real? Is the hype coding. Like, is this real? Is the hype real? So I went deeper and then more

real? So I went deeper and then more real? So I went deeper and then more announcements were made all the way up announcements were made all the way up announcements were made all the way up until last week when Figma config until last week when Figma config until last week when Figma config announced that code is now material. announced that code is now material. announced that code is now material. Does that mean there is no even handoff Does that mean there is no even handoff Does that mean there is no even handoff that exists anymore? Um so I'm that exists anymore? Um so I'm that exists anymore? Um so I'm monitoring trying to keep up. Things are monitoring trying to keep up. Things are monitoring trying to keep up. Things are happening at warp speed. happening at warp speed. happening at warp speed. But they said the roundtrip was solved But they said the roundtrip was solved But they said the roundtrip was solved and I started messing around and and I started messing around and and I started messing around and realized it wasn't. And so I want to realized it wasn't. And so I want to realized it wasn't. And so I want to share with all of you share with all of you share with all of you a harness that I built. Whoops. Oh, wait a harness that I built. Whoops. Oh, wait a harness that I built. Whoops. Oh, wait a minute. Local host, where are you? a minute. Local host, where are you? a minute. Local host, where are you? Local host, Local host, Local host, come back to me, local host. Okay. come back to me, local host. Okay. come back to me, local host. Okay. I don't know what I don't know what just I don't know what I don't know what just I don't know what I don't know what just happened there. And now I'm afraid to happened there. And now I'm afraid to happened there. And now I'm afraid to restart this. Um, okay. I think we're I restart this. Um, okay. I think we're I restart this. Um, okay. I think we're I think we're okay. Um, I created this think we're okay. Um, I created this think we're okay. Um, I created this harness. And what this harness is is on. harness. And what this harness is is on. harness. And what this harness is is on. I'm going to say left. I hope everybody I'm going to say left. I hope everybody I'm going to say left. I hope everybody is that your left. It is your left. is that your left. It is your left. is that your left. It is your left. Okay, good. [laughter] Okay, good. [laughter] Okay, good. [laughter] On your left is code that was generated On your left is code that was generated On your left is code that was generated by AI. This is this is all real what by AI. This is this is all real what by AI. This is this is all real what you're seeing here. Generated by AI and you're seeing here. Generated by AI and you're seeing here. Generated by AI and on your right is a design. Be it a on your right is a design. Be it a on your right is a design. Be it a canvas that that I created in Figma, be canvas that that I created in Figma, be canvas that that I created in Figma, be it something I created in Sketch. It's it something I created in Sketch. It's it something I created in Sketch. It's not really relevant what the sources are not really relevant what the sources are not really relevant what the sources are here, but the reality is I'm trying to here, but the reality is I'm trying to here, but the reality is I'm trying to illustrate a round trip. And so a round illustrate a round trip. And so a round illustrate a round trip. And so a round trip you know starts with code or starts trip you know starts with code or starts trip you know starts with code or starts with design and it has a prompt with design and it has a prompt with design and it has a prompt associated with it. So some some LLM I associated with it. So some some LLM I associated with it. So some some LLM I call off and I say in this instance I

call off and I say in this instance I call off and I say in this instance I want to take this form and I want to want to take this form and I want to want to take this form and I want to build a design system from it. So there build a design system from it. So there build a design system from it. So there there are tools that do this that can there are tools that do this that can there are tools that do this that can extract code and build design systems extract code and build design systems extract code and build design systems from graphical canvases. And so I can do from graphical canvases. And so I can do from graphical canvases. And so I can do that. And it updated the code and that. And it updated the code and that. And it updated the code and created some styles. And it also created some styles. And it also created some styles. And it also actually created um a design system that actually created um a design system that actually created um a design system that works in runtime here. So this is like a works in runtime here. So this is like a works in runtime here. So this is like a a real app that got built that is also a real app that got built that is also a real app that got built that is also living in Figma. So there's a link up living in Figma. So there's a link up living in Figma. So there's a link up here. I won't go there, but trust me, so here. I won't go there, but trust me, so here. I won't go there, but trust me, so we can say stable. If I click that link, we can say stable. If I click that link, we can say stable. If I click that link, it would go to Figma and show me the it would go to Figma and show me the it would go to Figma and show me the full-blown design system that was built. full-blown design system that was built. full-blown design system that was built. And a design system for those that don't And a design system for those that don't And a design system for those that don't know is composed of components and know is composed of components and know is composed of components and tokens and variables and styles that all tokens and variables and styles that all tokens and variables and styles that all are used as a basis for building are used as a basis for building are used as a basis for building software from. So code and design software from. So code and design software from. So code and design together, you know, really work well together, you know, really work well together, you know, really work well when there's a design system and there's when there's a design system and there's when there's a design system and there's a code base that understands it. Now a code base that understands it. Now a code base that understands it. Now move back and forth. You throw something move back and forth. You throw something move back and forth. You throw something over here and you say, "Okay, I want to over here and you say, "Okay, I want to over here and you say, "Okay, I want to build an orange button." And I've added build an orange button." And I've added build an orange button." And I've added a company field and an orange button.

a company field and an orange button. a company field and an orange button. The code is updated. The design is The code is updated. The design is The code is updated. The design is updated. This is awesome. Could I go updated. This is awesome. Could I go updated. This is awesome. Could I go back? Maybe. Um, but I have a button up back? Maybe. Um, but I have a button up back? Maybe. Um, but I have a button up here called show drift. here called show drift. here called show drift. So, show drift is rewaver AI working So, show drift is rewaver AI working So, show drift is rewaver AI working right now. And this is real rewaver code right now. And this is real rewaver code right now. And this is real rewaver code for the first time introduced to the for the first time introduced to the for the first time introduced to the public ever. And if I click show drift, public ever. And if I click show drift, public ever. And if I click show drift, I'll see a list of issues that got I'll see a list of issues that got I'll see a list of issues that got generated from both the code and the generated from both the code and the generated from both the code and the design at the same time. There are design at the same time. There are design at the same time. There are across several different dimensions that across several different dimensions that across several different dimensions that you can see here. Design quality, code you can see here. Design quality, code you can see here. Design quality, code quality, performance, design tokens, quality, performance, design tokens, quality, performance, design tokens, etc. One of the ones of note that I find etc. One of the ones of note that I find etc. One of the ones of note that I find really important from my perspective is really important from my perspective is really important from my perspective is at Microsoft I worked on accessibility at Microsoft I worked on accessibility at Microsoft I worked on accessibility and I learned a lot about what it means and I learned a lot about what it means and I learned a lot about what it means to build an accessible software system. to build an accessible software system. to build an accessible software system. And I I want to be honest with all of And I I want to be honest with all of And I I want to be honest with all of you. I was very frustrated when I first you. I was very frustrated when I first you. I was very frustrated when I first saw LMS come out and they generated code saw LMS come out and they generated code saw LMS come out and they generated code that was inaccessible period out of the that was inaccessible period out of the that was inaccessible period out of the box. I thought what models weren't box. I thought what models weren't box. I thought what models weren't trained on accessibility.

trained on accessibility. trained on accessibility. Um, and I was reminded 20 years ago when Um, and I was reminded 20 years ago when Um, and I was reminded 20 years ago when you know engineers needed to be trained you know engineers needed to be trained you know engineers needed to be trained on accessibility. So here we are again on accessibility. So here we are again on accessibility. So here we are again now training LLMs instead of engineers now training LLMs instead of engineers now training LLMs instead of engineers on accessibility. on accessibility. on accessibility. So found issues. Um, here's an issue So found issues. Um, here's an issue So found issues. Um, here's an issue where where where has no Arya live region. So it won't be has no Arya live region. So it won't be has no Arya live region. So it won't be announced by screen reader. A blind user announced by screen reader. A blind user announced by screen reader. A blind user using this won't get an announcement using this won't get an announcement using this won't get an announcement about this element. So Rewaver found about this element. So Rewaver found about this element. So Rewaver found that and Rewaver says it can fix it and that and Rewaver says it can fix it and that and Rewaver says it can fix it and Rewaver fixed it. Now the red went away, Rewaver fixed it. Now the red went away, Rewaver fixed it. Now the red went away, but there's also a blue issue here as but there's also a blue issue here as but there's also a blue issue here as well. Um so Rewaver stacks up issues and well. Um so Rewaver stacks up issues and well. Um so Rewaver stacks up issues and you know basically scans scans the code you know basically scans scans the code you know basically scans scans the code and scans the design and produces u and scans the design and produces u and scans the design and produces u guard rails to a sense but also a way to guard rails to a sense but also a way to guard rails to a sense but also a way to fix the code and make it better. fix the code and make it better. fix the code and make it better. So I did that across multiple dimensions So I did that across multiple dimensions So I did that across multiple dimensions um you know with the intention of seeing um you know with the intention of seeing um you know with the intention of seeing if anybody had solved the drown the the if anybody had solved the drown the the if anybody had solved the drown the the roundtrip problem roundtrip problem roundtrip problem and it didn't go well. Uh I never got and it didn't go well. Uh I never got and it didn't go well. Uh I never got really the full round trip. So I really really the full round trip. So I really really the full round trip. So I really tried hopefully this slide tells you I tried hopefully this slide tells you I tried hopefully this slide tells you I tried five different tool setups trying tried five different tool setups trying tried five different tool setups trying to do code design code roundtrip both to do code design code roundtrip both to do code design code roundtrip both directions birectional directions birectional directions birectional lots of lossy issues uh you know lots of lossy issues uh you know lots of lossy issues uh you know bindings were lost um design change bindings were lost um design change bindings were lost um design change survived but code didn't survived but code didn't survived but code didn't I'm not going to say we're not going to I'm not going to say we're not going to I'm not going to say we're not going to get there um but even if we do get there get there um but even if we do get there get there um but even if we do get there and we're able to do this I wonder if

and we're able to do this I wonder if and we're able to do this I wonder if we'll get fully there And maybe we need we'll get fully there And maybe we need we'll get fully there And maybe we need tools like Reweaver. I shouldn't say tools like Reweaver. I shouldn't say tools like Reweaver. I shouldn't say maybe, we do need tools like Reweaver to maybe, we do need tools like Reweaver to maybe, we do need tools like Reweaver to help us understand the drift. help us understand the drift. help us understand the drift. So that whole experience for me really So that whole experience for me really So that whole experience for me really highlighted something from my past. Um I highlighted something from my past. Um I highlighted something from my past. Um I had I had built a lot of software had I had built a lot of software had I had built a lot of software development tools, designed and built development tools, designed and built development tools, designed and built software development tools and developer software development tools and developer software development tools and developer tools in their nature are deterministic. tools in their nature are deterministic. tools in their nature are deterministic. You write code, you compile it, you get You write code, you compile it, you get You write code, you compile it, you get an SA a it it'll every time you run that an SA a it it'll every time you run that an SA a it it'll every time you run that code, you'll get the same result. When code, you'll get the same result. When code, you'll get the same result. When you put AI in the middle of that or in you put AI in the middle of that or in you put AI in the middle of that or in the front of that or the end of that, the front of that or the end of that, the front of that or the end of that, you're not going to necessarily get the you're not going to necessarily get the you're not going to necessarily get the same outcomes. Now, there are tools that same outcomes. Now, there are tools that same outcomes. Now, there are tools that will help you understand, rewaver being will help you understand, rewaver being will help you understand, rewaver being one of them, that there's a mismatch. one of them, that there's a mismatch. one of them, that there's a mismatch. There's drift there and we need to be There's drift there and we need to be There's drift there and we need to be aware of drift. Drift lurks in the dark. aware of drift. Drift lurks in the dark. aware of drift. Drift lurks in the dark. You need to look at the code. You need You need to look at the code. You need You need to look at the code. You need to find the drift. You need to fix the to find the drift. You need to fix the to find the drift. You need to fix the drift. And you do that with drift. And you do that with drift. And you do that with deterministic guardrails around the AI. deterministic guardrails around the AI. deterministic guardrails around the AI. The AI is still there. So I ran another The AI is still there. So I ran another The AI is still there. So I ran another experiment, 12 iterations on a codebase experiment, 12 iterations on a codebase experiment, 12 iterations on a codebase with complex enough UI to it. And I did with complex enough UI to it. And I did with complex enough UI to it. And I did one where it was just pure AIE, just LLM one where it was just pure AIE, just LLM one where it was just pure AIE, just LLM all the way. And it degraded a little.

all the way. And it degraded a little. all the way. And it degraded a little. It degraded a little bit, but it started It degraded a little bit, but it started It degraded a little bit, but it started at 30% quality, 30% fidelity, 30%, you at 30% quality, 30% fidelity, 30%, you at 30% quality, 30% fidelity, 30%, you know, true pixel perfection. know, true pixel perfection. know, true pixel perfection. And then I put it on top of And then I put it on top of And then I put it on top of deterministic guardrails where we found deterministic guardrails where we found deterministic guardrails where we found the issues, we fixed the issues. You the issues, we fixed the issues. You the issues, we fixed the issues. You can't get to a hundred because that 10% can't get to a hundred because that 10% can't get to a hundred because that 10% is human judgment, human is human judgment, human is human judgment, human decision-making. So the human is still decision-making. So the human is still decision-making. So the human is still there in this equation. there in this equation. there in this equation. Um, Um, Um, so what is it today? Uh, today I I would so what is it today? Uh, today I I would so what is it today? Uh, today I I would call it we're locked into AI. And that's call it we're locked into AI. And that's call it we're locked into AI. And that's okay. We'll go there. We'll embrace okay. We'll go there. We'll embrace okay. We'll go there. We'll embrace that. But we're locked into AI for that. But we're locked into AI for that. But we're locked into AI for design to code. We're locked into AI for design to code. We're locked into AI for design to code. We're locked into AI for code to design, looping, chat bots, what code to design, looping, chat bots, what code to design, looping, chat bots, what we call span the chain workflows where we call span the chain workflows where we call span the chain workflows where you jumping across tools. And there's you jumping across tools. And there's you jumping across tools. And there's always token costs to be aware of, of always token costs to be aware of, of always token costs to be aware of, of course. So in this world, the agents are course. So in this world, the agents are course. So in this world, the agents are in control and the humans in the loop. in control and the humans in the loop. in control and the humans in the loop. I'd like to propose something else. I'd like to propose something else. I'd like to propose something else. Before I do, there are three blind spots Before I do, there are three blind spots Before I do, there are three blind spots we need to be aware of. One is the model we need to be aware of. One is the model we need to be aware of. One is the model itself. It's going to you can ask it itself. It's going to you can ask it itself. It's going to you can ask it questions. It'll give you answers, but questions. It'll give you answers, but questions. It'll give you answers, but it's nondeterministic. It's it's nondeterministic. It's it's nondeterministic. It's probabilistic.

probabilistic. probabilistic. There will be drift in the moment when There will be drift in the moment when There will be drift in the moment when you're writing code. Drift will surface, you're writing code. Drift will surface, you're writing code. Drift will surface, but drift over time is the pain that but drift over time is the pain that but drift over time is the pain that you'll be experiencing for the next six you'll be experiencing for the next six you'll be experiencing for the next six months because drift over time is the months because drift over time is the months because drift over time is the new tech debt and it's going to pile new tech debt and it's going to pile new tech debt and it's going to pile itself itself itself gloriously over your codebase. Um, we gloriously over your codebase. Um, we gloriously over your codebase. Um, we want to do something about it. So here's want to do something about it. So here's want to do something about it. So here's where we think it isn't meaning what it where we think it isn't meaning what it where we think it isn't meaning what it could be what it should be fully could be what it should be fully could be what it should be fully birectional birectional birectional edit both ways lossless all surfaces edit both ways lossless all surfaces edit both ways lossless all surfaces preserved so if you go from code to preserved so if you go from code to preserved so if you go from code to design and design to code nothing's design and design to code nothing's design and design to code nothing's breaking weirdly for you provenence is breaking weirdly for you provenence is breaking weirdly for you provenence is carried where did this start from what carried where did this start from what carried where did this start from what line of code wrote this button line of code wrote this button line of code wrote this button I see this button in Figma I want to I see this button in Figma I want to I see this button in Figma I want to change it I need to change that code or change it I need to change that code or change it I need to change that code or Somebody needs to change that code. We Somebody needs to change that code. We Somebody needs to change that code. We have to control the drift. It's have to control the drift. It's have to control the drift. It's deterministic reconciliation at its deterministic reconciliation at its deterministic reconciliation at its core. So with deterministic guardrails, core. So with deterministic guardrails, core. So with deterministic guardrails, and I'm happy to talk after if folks are and I'm happy to talk after if folks are and I'm happy to talk after if folks are interested in what I mean by that, interested in what I mean by that, interested in what I mean by that, accept or refuse. So if they know accept or refuse. So if they know accept or refuse. So if they know there's a fix, they will fix it. If they there's a fix, they will fix it. If they there's a fix, they will fix it. If they don't know there's a fix, they will tell don't know there's a fix, they will tell don't know there's a fix, they will tell you there's an issue, but you need to you there's an issue, but you need to you there's an issue, but you need to fix it.

fix it. fix it. And with Ruby Weaver, there's zero extra And with Ruby Weaver, there's zero extra And with Ruby Weaver, there's zero extra token costs. So, we're fully local LLM, token costs. So, we're fully local LLM, token costs. So, we're fully local LLM, but if you want to open up Claude or but if you want to open up Claude or but if you want to open up Claude or whatever and connect to us, you can. But whatever and connect to us, you can. But whatever and connect to us, you can. But at its core, and our core principle is at its core, and our core principle is at its core, and our core principle is the human is in control always. In the human is in control always. In the human is in control always. In control of cost, in control of code, in control of cost, in control of code, in control of cost, in control of code, in control of design, because that's what control of design, because that's what control of design, because that's what we've been doing for decades. we've been doing for decades. we've been doing for decades. We've been in control. We don't need to We've been in control. We don't need to We've been in control. We don't need to lose control. And I'm not saying loop lose control. And I'm not saying loop lose control. And I'm not saying loop isn't good, but human in control is I isn't good, but human in control is I isn't good, but human in control is I think a little more aspirational think a little more aspirational think a little more aspirational because at the end of the day, what you because at the end of the day, what you because at the end of the day, what you need is actually what you get. I call it need is actually what you get. I call it need is actually what you get. I call it winnywig. Can I use that winny wig? winnywig. Can I use that winny wig? winnywig. Can I use that winny wig? So what are we building at its core? So what are we building at its core? So what are we building at its core? What we're building are nine dimensions What we're building are nine dimensions What we're building are nine dimensions of deterministic guardrails. of deterministic guardrails. of deterministic guardrails. Inside of this is a lot of stuff, but Inside of this is a lot of stuff, but Inside of this is a lot of stuff, but these are our top level um software these are our top level um software these are our top level um software quality, software production readiness quality, software production readiness quality, software production readiness dimensions. Design consistency being dimensions. Design consistency being dimensions. Design consistency being core. Of course, when you have a design core. Of course, when you have a design core. Of course, when you have a design system and the code isn't consistent system and the code isn't consistent system and the code isn't consistent with it and vice versa, we need to fix with it and vice versa, we need to fix with it and vice versa, we need to fix that. So, there's a lot of design that. So, there's a lot of design that. So, there's a lot of design consistency consistency consistency um work that's going into the the um work that's going into the the um work that's going into the the foundation. Accessibility is its own foundation. Accessibility is its own foundation.

You can scan it and get your the left. You can scan it and get your the left. You can scan it and get your results for that code. There's also a results for that code. There's also a results for that code. There's also a fun little challenge on that page. If fun little challenge on that page. If fun little challenge on that page. If you can get AI to generate code that you can get AI to generate code that you can get AI to generate code that gives you a score lower than30 gives you a score lower than30 gives you a score lower than30 PDR, PDR, PDR, which is production drift ratio, will which is production drift ratio, will which is production drift ratio, will get you a frontline seat on the beta, get you a frontline seat on the beta, get you a frontline seat on the beta, but you'll also get yourself showcased but you'll also get yourself showcased but you'll also get yourself showcased at the bottom on the crawl. So, give it at the bottom on the crawl. So, give it at the bottom on the crawl. So, give it a shot. Take a look. Um, meanwhile, I'm a shot. Take a look. Um, meanwhile, I'm a shot. Take a look. Um, meanwhile, I'm looking for people to join our beta.

looking for people to join our beta. looking for people to join our beta. We're going to basically blast out mid We're going to basically blast out mid We're going to basically blast out mid July hopefully. July hopefully. July hopefully. Um so would love for you to join if Um so would love for you to join if Um so would love for you to join if you're interested um to make the product you're interested um to make the product you're interested um to make the product better to sanity check us.
