# Keep pages up to date

Knowledge: read a changed page again with Refresh, pick up new pages with Re-fetch, and re-read every page on a schedule with Auto-refresh: every 3 months, every month or every day.

This is the Markdown version of https://www.meetdarwin.ai/help/knowledge/keep-pages-up-to-date, published by Darwin and generated on 27 October 2026.

Find it in Darwin: Knowledge (https://app.meetdarwin.ai/admin/agent?tab=knowledge). Updated Oct 26, 2026.

Darwin answers from its last read of each page. When your website changes, read the page again, or let Darwin re-read every page on a schedule.

1. **Refresh a page you changed**

   Select **Knowledge** in the sidebar and scroll the table to the right. Select **Refresh** (2) beside the page. Darwin reads it again straight away, and **Last read** updates. This doesn't wait for **Save changes**.

2. **Pick up new pages on your site**

   Select **Add knowledge**, then **Re-fetch** beside your site under **Sites and sitemaps**. Darwin checks the site for pages it hasn't seen and lists them in the table; tick **Use** on the ones your agent should answer from, then select **Save changes**.

3. **Re-read every page on a schedule**

   Open **Auto-refresh** above the table. Under **Read every page again**, choose **Every 3 months**, **Every month** or **Every day**, then select **Save changes**. Choose **Off** to stop.

   _Screenshot: The Auto-refresh menu open under Read every page again: Every 3 months, Every month, Every day, and Off, which is ticked._

   **Every day** is on Growth and Agency. On Free, choosing it offers the upgrade; a workspace on **Every day** that moves to Free is re-read every month instead.

## Good to know

- **Refresh** and **Re-fetch** work on every plan, as often as you need.
- New pages are read within minutes. While pages are waiting, a line above the table says **Reading** and how many, with **Read now** to read them straight away.
- If a re-read fails, your agent keeps the copy it read before and the page shows **Refresh failed**. See [Fix a page Darwin couldn't read](https://www.meetdarwin.ai/help/knowledge/fix-a-page-darwin-couldnt-read).
- **Reporting → Knowledge** counts pages last read more than 30 days ago as stale. Documents you upload never go stale.
