Kris Puckett, Design Manager at Stripe, spent months building Epilogue, a real iOS app with 14,000 lines of Swift, entirely through conversation with Claude. This essay is a specific and honest account of what the designer-building-with-AI experience actually looks like: what broke, what he learned about asking precise questions, what “vague frustration keeps you stuck, specific confusion gets you answers” actually looks like in practice. “I realized the bottleneck was never coding ability. It was articulation. The ability to describe what I wanted clearly enough that something else could build it.”
“Designers have always (and will always) answer the question ‘What’s worth making?’ ” Joel Lewenstein, Head of Design at Anthropic, argues that as the cost of software drops, the most important decisions shift from “can we make this?” to “should we?” Design, in his framing, is what narrows the possibility space fast enough to keep up with the speed of delivery. He describes Claude Design as a tool for getting ideas “good enough to move discussion forward,” cutting idea-to-internal-feedback time from days to hours.
Design twitter is spicy today with Claude Design coming out but what if, like Canva, this is yet another onramp to design for hundreds of millions of people?

What if it’s not a Claude Design vs. Canva vs. Figma vs. xxx but a “yes and” as millions more people are exposed to…
while I didn’t like Claude design at first try, it’s clear this is where we’re heading for the most part (assuming we’ll also get a full canvas env to explore visually alongside)

this post from @samhenrigold on the topic is spot on, so much I agree with here. I’m a diehard Figma… pic.twitter.com/8DjKygJ5gR
Jacob Miller left the PM role at Figma to build Diffui, a new way to approach the design to dev process with AI. In this thread, he compares designs generated by his tool and Claude Design. One is more expressive and diverse, another is more polished and organized. The point is not that one is better than another, but how can we combine different approaches and tools to get to the most interesting result.

First up - designs for a surf shop.
Diffui put out 9 designs, below are my 3 picks vs what Claude put out. Which do you prefer? pic.twitter.com/qm9Ju3Pr8k
Most confusion about the future of software design stems from a confusion in terminology.

My view: production design will increasingly be automated. The economic logic is self-evident — training machines to mimic and refine existing production practices is cheaper, faster, and… https://t.co/PloV4Tni9T
This is really neat but it’s not a design tool as much as it’s a design _production_ tool.
— Rasmus Andersson (@rsms) April 17, 2026
The practice of design is mostly about what comes before production.
There’s no doubt in my mind that all parts of software production will become automated very soon. Writing code,… https://t.co/4YFFZZdwCt
Gui Seiz and Alex Kern from Figma walk through the exact workflow they use to keep design and code in continuous sync using Figma’s MCP, Claude Code, and Codex. Their demo shows the full round-trip: pull a running web app into Figma as editable frames, make design changes on the canvas, push them back to code via Claude Code. If you’d rather read than watch the full video, the newsletter summary of this How I AI episode captures the key takeaways.
Ridd walks through a workflow where Paper acts as a visual canvas that Claude can “proactively” explore and prototype in. The interesting bit is his framing of Claude Code as a coworker and Paper as a shared whiteboard. That’s exactly what I wanted when last week I commented on missing agents in Figma after spending more time in Cursor.
I just had my aha moment with @paper 🙌

This is pretty much exactly what I want my design workflow to look like moving forward pic.twitter.com/EvCmHc4cck
Jenny Wen leads design for Claude at Anthropic, and in the past, she was Director of Design at Figma, where she led the teams behind FigJam and Slides. At Lenny’s podcast, she lays out how AI is collapsing the classic “research → mock → iterate” workflow into two main jobs for designers: supporting rapid implementation alongside engineers, and setting shorter 3–6 month product visions that keep a swarm of agents and builders pointed in a coherent direction. Jenny describes the day-to-day at Anthropic as equal parts surfing internal prototypes, pairing with engineers, and doing last-mile implementation herself. She still sees Figma as critical for exploring many directions and fine visual decisions, but treats Claude as her primary stack for long-running tasks and front-end polish.
“Bringing Claude Code workflows directly into Figma lets developers, designers, and even hobbyists capture a real, functioning UI from a browser — in production, staging, or localhost — and convert it into editable frames on the Figma canvas. Code is powerful for converging — running a build, clicking a path, and arriving at one state at a time. The canvas is powerful for diverging — laying out the full experience, seeing the branches, and shaping direction collectively. Going from code to canvas helps teams move fluidly, so work can narrow when it needs to and open up when it’s time to collaborate.”
My guess is it’s based on the html.to.design technology that Figma acquired last year, which is a huge time saver and an essential part of my toolkit. I haven’t tested Claude Code to Figma yet, but the result in demos looks very similar to what I usually get from the plugin. Which makes me wonder why they limited it to Claude Code instead of making something like a universal “Send to Figma” browser extension?
