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.
Turn a rough product idea into a PRD draft in seconds
Enter your product name, feature name, overview, feature list, and user feedback, then click Generate My PRD to receive a structured draft written by ChatGPT.
The generator is built on ChatGPT, so the draft follows recognizable PRD structure and is phrased as editable product-manager prose rather than raw bullet fragments.
Add the WriteMyPRD bot to Slack and it will ask what your product does, then help you start the PRD right inside your team's workspace.
A 'Try with a sample requirement' button fills the form with an example so you can see the output quality before investing effort in your own input.
