Document API changes automatically and ship accurate release notes
Register your API environments and the platform monitors them for changes, so nothing is missed between releases.
Output follows the OpenRelease standard, giving every release a consistent, reviewable structure instead of an ad-hoc bullet list.
Publish as HTML or email, or export structured JSON, YAML and PDF on higher tiers for downstream tooling.
Push notes to Slack, Dropbox, S3 or a wiki, or send them by email, reaching engineers, PMs and customers from one source.
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.
