What I want from an AI product design app
(this doesn't exist yet)
A place to build and utilize my official design system.
Direct connection to my product's real codebase — with changes submitted via branches and merge requests.
A visual interface to design complex screens and multi-state flows — using realistic dummy data copied or generated from my app — making precise edits in a tool just as powerful as Figma.
The ability to create a prototype that's built on my app's real code from my designs.
Easy publishing of the prototype to a unique URL so stakeholders can interact with it without breaking anything.
A seamless handoff: submit designs directly to a branch so engineers can review and create a merge request.
AI assistance throughout — offering micro design critiques, accessibility help, idea generation, nudges from the design system and past work, hints from user research (which it also helped synthesize), and more.
From what I'm seeing in products like Subframe, Onlook, Tempo, and Paper, I'm convinced we're getting close.
But we’re not there yet.
