AI document assistant that drafts PRDs, help docs and wikis from a short brief
Describe a problem and a feature, and get a structured first draft you can adapt to your team's PRD template.
Highlight a section and let AI expand, restructure or refine it, with tools like PRD Review that surface gaps before you ship.
Turn a short text prompt into flowcharts, sequence diagrams, Gantt charts and other professional diagrams.
Work in the same document simultaneously, follow edit history, and organize complex documentation in flexible hierarchies.

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.
