Redesign the screen you actually shipped.

Start from a capture

Pick a route and viewport from what was actually rendered to users, and edit that.

Wayback

Move back through captures by day to work against how the screen looked before a change, not only how it looks now.

Figma import

Bring a design in when the starting point is a comp rather than a shipped screen.

Select an element

Click a node in the preview to aim your next instruction at it, instead of describing which button you mean.

Preview or code

Switch between the rendered result and the markup behind it, and export the code when you want it elsewhere.

Multiple threads, one canvas

Several conversations can share the same prototype, so exploring an alternative does not mean starting over.
