AI-generated product development reports from your Jira and Linear activity
Weekly updates, sprint reports, standup digests and executive summaries are generated automatically from your issue tracker activity.
AI explains what the numbers mean in plain language, highlighting sprint themes, goals and progress instead of leaving metrics uninterpreted.
The AI uses the structure of your epics to surface themes across loose tasks and zooms in on progress at a glance, with sources so you can investigate.
The AI flags delivery risks and makes practical suggestions so you can act before problems derail a project.

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.
