History
See every revision of a page, who made each change, and how a page looked in the past.
Known keeps every version of every page and records who made each change. You can see what a page said at any point in the past and what changed in a wiki over time.
Changes and revisions
Each write to a wiki creates a change. A change has a number, an author, a message, and a time. A single change can affect several pages, for example when you move a page with the pages under it. Each page the change affects gets a new revision.
Records keep a separate history. For tables, Known keeps every version of each row. See Records.
Authors
Every change records its author:
| Author | Shown as |
|---|---|
| A person | Their name, and where they made the change: the browser, the CLI, or a site. |
| A connected agent | The agent and the person it acted for, for example "Claude for Ana". |
| The Known assistant | The assistant and the person who asked, for example "Known assistant for Ana". |
Page history can't be deleted, by people or by agents.

FAQ
How far back can I see history?
On the Free plan, you can see the last 90 days. Older history is kept and becomes visible when you upgrade. See Plans and limits.
Can history be deleted?
Page history can't be deleted. Records can lose old versions if the page sets a retention limit. See Schemas and retention.
