Product context that keeps AI and teams building the right thing
Builds a shared vocabulary from your own docs so terminology stays consistent and AI tools stop assuming how your product works.
Stories keep decisions, feedback, implementation notes, usage analytics and feature flags attached so context survives beyond sprint planning.
Design decisions, investigations and code changes are captured on stories and picked up automatically by Claude, Cursor or Copilot.
Idea, roadmap, workflow, stories, bugs, flags and engagement live on the same object for a single connected workspace.

The collaborative whiteboard built for product builders
AI Flowcharts, AI Mind Maps and AI Wireframes convert a short text prompt into structured, fully editable diagrams, branched mind maps, or web and mobile wireflows — no manual drawing required.
Boards host diagrams, flowcharts, mind maps, wireframes, embedded media and documents side by side, so a whole product narrative lives in a single shareable file.
Multiple teammates edit the same board simultaneously with live cursors, thread comments attached to specific objects, and mention-based notifications.
Drag-and-drop UI components let teams sketch screens, link them into clickable flows and iterate on product ideas before engineering commits to a build.
