One thing I think Subframe gets right—and most prompt-to-UI tools completely miss—is divergence. Subframe brings that back. If AI tools want to support real design workflows, they need to mirror how we actually think.

Arvind SubramanianCo-Founder @ Contour (YC S23)

Highly recommend it for backend-heavy teams that need to ship quality UI quickly.

I ran an AI-powered design sprint using Subframe. By the middle of Day 1, we had generated MULTIPLE concepts that looked and felt real.

Ji Su HiattSenior Product Designer @ NMI

Tools like Subframe are blurring these boundaries by creating a shared language — code—that all team members can understand and contribute to.

Subframe feels like a game changer. Instead of handing off static mocks, you’re designing with real structure, real components, and real code - so what you make is what gets built.

Rashi BihaniDesign Director @ AI Student Collective

As AI transforms tech, a designer's judgement, taste and influence will matter more than ever. Subframe is one of my favorite new AI tools to visually build your product UI in minutes.

Subframe feels like a designers take. It feels like it's there to care about and work on the design.

Micke AlmStaff Product Designer & Design Lead

I've been using this for months and it's easily the best level of abstraction for building UI of any tool I've used (and I've tried a bunch).

Hansen QianFounder @ Lightski (YC W23)

Subframe is an interesting approach to building apps grounded in strong design systems. Any tool that helps raise the bar on quality is a win for users.

Patrice CalligarisFounder & Director of Product Design @ BestOfDesign

Subframe was a game changer for us. We went from design/UI being our Achilles' heel to it becoming one of the strengths of our product.

Fawad KhaliqCTO @ Chkk

With Subframe, 80% of the things I’m likely to need on a page are there at my fingertips. I don’t need to think about organisation and layout, just about what the ideal UX would be.

Tom WeaverFounder @ Chainmaker

It feels as though my creativity has been unburdened of the previous worry of a “hand-off gone bad.” Instead, I am more confident than ever that I can design, build and ship great products much more consistently.
