A collaborative whiteboard
where every object is real data.

What can bind

• Charts — to a table, sheet, Hub list, Kanban, poll or quiz, with Excel-style pivot aggregation on the way through: count, sum, average, min or max, grouped by one field and optionally split into series by another.
• Shape labels and fills — to a single row, so a process diagram recolours itself from live status instead of somebody repainting boxes before the review.
• Word clouds — to a text column, re-weighted as the column changes.

Conditional formatting

• Shapes carry rules that switch fill and stroke on a bound value.
• Hub lists carry list-wide rules that tint a record in every view at once — including date rules, so anything past today reads as overdue everywhere.
• Gantt and Kanban highlight overdue work and carry red/amber/green status of their own.

Running a session

• Focus spaces — admin-drawn regions in guided mode, which confines everyone to the current phase, or assigned mode, which gives each person their own. Late joiners can be locked out until admitted.
• Private mode — nobody sees anyone else’s notes until the host reveals them.
• Shared timer — event-based, so it stays in sync across everyone without ticking, with labels and laps.
• Present mode — frames and explicit steps, seven transitions, and per-object reveal builds triggered on click, with previous, or after previous.

Who can do what

• Four roles with a real capability matrix — a contributor edits contents but cannot create, move or delete — mirrored by database row-level security rather than hidden buttons.
• Confidential objects redacted from viewers, or from viewers and editors, on a board you are still sharing.
• Share links that carry a role and can expire or cap their own use count, with an access-request queue behind them.
• Version history with manual and automatic snapshots, and restore.

REST data API

Mint a personal access token and read any board’s tables, Hub lists, sheets, Kanbans, Gantts and polls as addressable datasets, plus structure feeds for objects and connectors. A token never reaches further than its owner’s own board role.

curl -H "Authorization: Bearer $BOARDOS_TOKEN" \

First-party MCP server

A JSON-RPC Streamable-HTTP endpoint. Point Claude, Cursor or any MCP client at it and your boards become context it can read.

• list_boardsevery board the token's owner can reach
• get_boardone board's full structure
• get_datasetany tabular object on it, as rows

Installable as a web app with offline support, on the Microsoft Store, and as a Microsoft Teams app.
