# 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](connect-your-agent.md)). 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](op-log.md).
- **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](settings.md#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](op-log.md) 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.md#every-notebook)). [Connect your agent](connect-your-agent.md) says how to set it up, what an agent can do, and how to give it instructions. See [Coming](#coming).

## See and undo what an agent did

1. Open the **Op Log**.
2. Type the agent's name in the box at the top, or pick it under the filter button, to see only its changes.
3. 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.
4. 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.

## Coming
