# Website knowledge

> How Replify reads your webpages, keeps them up to date, and protects your edits

A webpage is a source you assign to a knowledge set. Assistants that use the set answer from it. For sets, items, and sitemaps, see [Knowledge](/assistant-setup/knowledge).

## How webpages become knowledge

Replify reads the page with a new reader that pulls much more complete information, then turns it into items.

Related information is grouped into one item. For example:

* All of your gym hours
* The full amenities list
* All of your pricing

Your assistant uses only a few items per question, so one complete item answers better than several fragments. See [Items](/assistant-setup/knowledge#items).

To add several pages at once, start from a sitemap and assign each page to a set. A sitemap is not a source. See [Sources](/assistant-setup/knowledge#sources).

### See what was read

Open the source on the **By source** tab and select **⋯ > View page content**.

The preview is text only. Images are not shown.

## Re-read schedule

Each webpage can stay up to date on a schedule, so you don't refresh it by hand.

| Schedule | What happens |
| - | - |
| **Weekly** | Re-read automatically every week |
| **Monthly** | Re-read automatically every month |
| **Manual** | Re-read only when you select **Re-read now** |

**Re-read now** runs immediately. On a weekly or monthly page, it is an extra re-read. The schedule continues as usual.

Change the schedule under **⋯ > Settings**.

## What happens on a re-read

| On the page | What happens |
| - | - |
| New information | Becomes new items |
| Changed information | Updates the matching items |
| Information that's no longer there | The matching items are **turned off**. They stay in [change history](/assistant-setup/managing-knowledge-items#change-history). |
| Nothing changed | The items stay as they are. No duplicate is created. |

Written knowledge and [locked items](#lock-items-to-protect-your-edits) stay as they are.

## Focus instruction

A focus instruction is optional. Replify adds it to the built-in instructions every time the page is read.

> Focus on class times; ignore club promos.

Set it when you add the page, or later under **⋯ > Settings**.

## Lock items to protect your edits

Lock a website item after you correct something the website gets wrong.

On the next re-read, the locked item stays as you wrote it, and no duplicate is created for that information.

* **One item:** select the lock icon in the **Locked** column.
* **Several items:** select them, then choose **Lock from re-read**. On the By set and All items tabs, this is under **Advanced**.

Only website items can be locked.

> [!TIP]
>
> To keep a fact out for good while it is still on your website, turn the item off and lock it.

## Pages added before this release

Websites added on the previous Knowledge page were read once. They are not on a re-read schedule.

To keep one up to date, add the page again with a schedule, then delete the old source.

## If a page can't be read

**Last read failed** means the items already read from that source stay as they are.

A security service, such as Cloudflare, usually causes this by blocking automated access. You can:

* Ask your website team to allow access for a short time, then select **Re-read now**.
* Print the page to PDF and upload it as a document.
* Copy the key information and add it with **Write knowledge**.
