People and agents
AI agents, such as Claude, can write in your notebook beside you, and every change says who made it.
They can work in the same page, even in the same block, at the same time.
An agent connects from Settings › Connections (see Connect your agent). Today only the founders use it. It is not open to other people yet coming.
Writing at the same time
- A change reaches your other devices as it syncs.
- Two writers can change the same block. Changes to different words both stay.
- If both change the same words, the block keeps both versions until you pick one. Two versions shows in the sidebar with a count. Open it and click Keep this on the one you want. The other stays in the Op Log.
- Your name, in Settings, sets the name shown on your writing.
You can share a notebook with other people, each at Can view, Can suggest, Can edit or Full access. See Sharing.
How agents write
An agent writes in the same notebook you see, and its changes sync to your other devices as yours do. It has its own name, so its work is never mixed up with yours:
- Each change it makes is in the Op Log under its name, marked ✦.
- A number beside Op Log in the sidebar counts the changes agents made since you last opened the Op Log on this device.
In Settings › Connections, give your agent a name and pick what it may do: Can view, Can suggest, Can edit or Full access, and where. One connection works in all your notebooks, at the level you pick in each (see One agent, every notebook). Connect your agent says how to set it up, what an agent can do, and how to give it instructions. See Coming.
See and undo what an agent did
- Open the Op Log.
- Type the agent's name in the box at the top, or pick it under the filter button, to see only its changes.
- Click a sitting to see its changes. Point at one for Open the block, or Undo this to take it back. Undo this sitting takes the whole sitting back.
- Or click Restore to here… on a sitting to undo everything the agent did after it. Your own changes, and other people's, stay.


Who wrote what
Open the ⋯ menu at the top right of a page and pick Show who wrote what. Each run of words is shaded in its writer's color, and a key at the top names each writer. Blocks cannot be edited while it is on. Pick Hide who wrote what to go back.
