One canvas for the whole loop — plan, build, review.
Show agents what you mean.
Create diagrams, write the plan in markdown, paste reference screenshots, draw wireframes — side by side on one board.
Connect your agents to our Desktop MCP Server and they'll build exactly what you put in front of them.
No more 2,000-word prompts describing user experiences.
Review your app screens, live all at once.
Add live previews of your app, rendered from your real source code: every route and state, side by side. Your whole team circles what is wrong right on the running UI, together in real time, and agents read the ink and fix exactly what you marked.
Prototype in parallel. Ship the winner.
Sketches are interactive prototypes agents generate in seconds — far cheaper to iterate than production code. Fork five directions, compare them side by side, then graduate the best one into real code in your repo.
What people do on the board.
Give UX feedback in ink
Circle the broken padding on the live app. The agent fixes exactly what you circled — no prose required.
Plan features agents can’t misread
A diagram and a markdown plan beat a 2,000-word prompt. Agents read the board and build what you drew.
Run a fleet, review at a glance
Several agents on several tasks — one canvas shows every screen that changed, side by side.
Prototype five takes before lunch
Fork a sketch into parallel variations, compare them live, keep the winner, ship it to your repo.
Decode unfamiliar code
Ask for an interactive diagram of how the system actually works. It’s in the name.
Design reviews with everyone
PMs, designers, engineers, and agents on one multiplayer board — requirements to working UI.
People have been waiting for this.
