have been considering putting together an IRL evening in San Francisco this summer with some other rad folks like @brian_lovin @intrater that are working on ~internal~ design prototyping tools. anyone interested?
While your team is just getting started vibe coding prototypes, the team at @stripe is vibe coding a full vibe coding platform. @ow is a design manager at Stripe who built Protodash - an internal AI prototyping tool that lets designers and PMs spin up real, clickable prototypes in minutes. In this ep he walks through: - why generic AI tools produce "blurple slop" that doesn't match your design system - how he built a full prototyping studio on top of dev boxes with cursor cc - why more PMs than designers now use Protodash - the design review mode that lets teams ship feedback direct in the app Plus, we talk about getting to the ultimate dream: demos, not memos. ty to our sponsors! 🧠 @Celigo - Intelligent automation built for AI 💻 @cursor_ai - The best way to code with AI Full episode on yt: youtu.be/hQFEAZK__q0

Super cool to be reading the (amazing) State of AI design report this morning and see the lil' prototyping tool I've been building show up in there ❤️ stateofaidesign.com/chapters…

I designed software for 15 years and never shipped an app of my own. I couldn't code, still can't. Then I learned how to talk to AI and shipped my first iOS app. I created NEUMA to teach you how to build and ship your ideas in as fast as a weekend. heyneuma.com

Tired of dealing with our annoying robot vacuum and have been eyeing up the @maticrobots… anyone have one and want to talk me down? 😅

It's posts like these that reinforce why my wife and I decided to build education.supply. > abundantly clear parents are actively searching for high quality products made for learning > there's a very wide spectrum in the relationship families have with putting tech in front of their kids. some families are entirely no-screen, others are working out how best to integrate (and when to introduce it). iPad alternatives are the most searched keyword on the site
Another iPad alternative is the Yoto player - audiobooks, podcasts, and music for kids. They also have an amazing BBC-style daily news report! Strong recommend.

im always like “alright better get cracking then bud” then dude hammers it out without blinking
when claude gives you a timeline of 1-2 weeks, is it aware it's gonna generate all the code in the next 5 minutes?

Joined @clairevo this week to record an episode of her podcast How I AI—had a blast hanging out and showing the prototyping tool i've been building internally at Stripe! The podcast is out on monday—but here's a sneak peek of our prototyping tool, Protodash, until then!

the stripe design team is hiring for some very fun roles helping define entirely new patterns for the internet, come join us!
Stripe’s product design team is growing! We’re hiring designers who care deeply about craft and want to shape how money moves on the internet. Including someone to lead the future of agentic commerce. We believe agentic commerce has the potential to be generationally impactful and need someone with an intense curiosity to explore, shape, and bring this new experience to life. stripe.com/jobs/listing/seni…

i should not have bought a 3d printer because every “problem” is now a day long rabbit hole of “oh i could just print that”

i swear i also get to blow people’s mind with the “double tap the time to go to top” thing too, they still don’t know!!!

it’s actually nuts how good AI has gotten at writing code i always lose receipts, so I wanted a tool to track them manuals, especially for large purchases started playing… 36 hours later I have a solid backend and a decent native iOS app(!!) already. it extracts info from receipts with an LLM, grabs the PDF of the manual a nice product photo from the internet and takes care of it all. ✨ just crazy how fast you can just make things real end-to-end now.

we made these fun test mode ones a while back at stripe. maybe i need to ship more hats.

i love that there are a bunch of different internal design teams coming up with super custom, powerful AI tools to unlock anyone designing software in code. I’ve talked to a few different companies about their approach and it’s been fun to see how we all approached it slightly differently
I've had "Write a post about Prototype Playground" on my todo list for 3 months now...fortunately, @clairevo invited me onto her podcast to talk about how it works and dig in to how we're prototype with AI @ Notion! Watch the video: youtube.com/watch?v=s4HGbIhU… Some thoughts: Prototype Playground has evolved quite a bit over the last year, and even since recording this in December, the app looks and feels quite different. But at it's core the Playground is simple: a single repository where anyone can explore ideas with AI and real code, unconstrained by the production codebase and without fear of breaking things. Prototype Playground is AI-first, naturally. We have skills that make developing and deploying easy, and they can help teach non-technical team members what's actually happening under the hood. Some of my favorites: /brainstorm — interviews you about what you're trying to make, think through edge cases, key flows, and finds components that can be reused from existing prototypes /deploy — walks through the entire branch → commit → push → PR → CI workflow and teaches people how git works along the way /find-icon — a script that helps find the right icon instance using synonyms, so "search icon" can resolve to "MagnifyingGlassIcon" in code We also have a few subagents that are particularly helpful: ci-monitor — watches CI on a pull request and self-heals broken tests, formatting issues, type errors, etc figma-verifier — uses the Figma MCP to loop back and forth between a Figma mock and what the agent built in the browser until the output is correct One of the most valuable parts of Prototype Playground is that everyone's work is in one place. It's easy to yoink great ideas from other people's prototypes or find that one random idea that would have otherwise been lost to a Slack thread...every prototype rolls up into a unified feed so we can see at a glance what people are exploring. It's worth mentioning: models have gotten so good in the last 3 months that we're seeing more designers at Notion prototype directly in production with feature flags. In the long-run I wonder how useful this type of isolated code-first prototyping environment will actually be... Also: in the video I mentioned that I was spending ~60% of my time in Figma. That is no longer true. It's now closer to 5-10%. The last 3 months of model improvements have changed what's possible to design and prototype in code. I can now multi-task different versions of an idea with parallel agents, kick off work to a background agent from my phone during a meeting, and agents can work for longer periods of time on more complex prototypes to build the core idea at a much higher level of fidelity. It's an incredibly exciting time to be a designer. Designers should embrace AI, learn how it works (there's no magic here!), and start developing an intuition for what models can do so that we're always building product experiences on the bleeding edge of capabilities. Let me know if you have any questions! I should still write that blog post...
