Blocknotes AI

AI's multiplayer moment is here.

Every tool that defined modern work won by going multiplayer. Docs beat Word. Figma beat Photoshop.

AI hasn't had that moment yet. It's the most powerful tool a team has ever been handed, and the one thing everyone still uses alone — a prompt, an answer, a box only you can see.

It's called Blocknotes AI.

Work lives in a blocknote: one shared space holding a project's sources, documents, conversations and agents. Your team joins it the way they'd join a doc.

Agents are in the room, not in a sidebar. Anyone can drop into the same live agent session — watch it, redirect it, approve the step that matters, hand it off. What it produces lands in the shared document as an editable, tracked change.

Every answer shows its work: bound to the exact paragraph it came from, one click away.

And permissions are compiled, not promised. Each session builds its own boundaries from who is in the room; bring a colleague in and they narrow instantly. That is why multiplayer is finally safe enough for real work.

Build agents, teams and workflows with a human in the loop where you want one. Publish them, compose them, reach them from anywhere through an open API and MCP.

This way, a project stops being a folder and becomes a room where people and agents think side by side.

If you believe AI should make teams sharper together rather than smarter separately, we built this for you.

The multiplayer era of work starts now. Join us.
