An AI work OS that finds your tasks and tells you what to do first
The proprietary PlansomScore algorithm ranks work by what needs attention now, weighing new requests and commitments against your existing goals and workload.
Connects to Gmail, Outlook, Slack, Notion, HubSpot and Granola to find tasks, commitments and decisions hidden in your communications and meetings.
Describe what you want to achieve and Plansom generates a structured plan with goals and the work needed to reach them, which you can edit and share.
Assign tasks to teammates with context attached, or activate built-in AI agents and track their activity and results from the same view.

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.
