Inline prototype feedback tool for designers

Build a tool that lets designers collect and manage feedback directly inside their interactive prototypes. Target UI/UX teams tired of disjointed feedback loops.

Why now

Design collaboration is moving into the prototype itself, as tools like Figma make live previews standard.

Who for
UI/UX design teams
Business model
Subscription per seat
Effort
A few weeks

Designers waste hours reconciling feedback scattered across emails, Slack, and screenshots. A browser extension or Figma plugin could overlay comments directly on interactive prototypes, threaded by version.

Charge design teams per seat, with agencies as ideal customers managing multiple client projects. Start by building a simple annotation layer for Figma prototypes before expanding to other platforms.

The risk is low adoption if big players like Figma bake this in natively.
