# Atlas

Atlas is ClearFeed’s native knowledge base. You can add Atlas as a Knowledge Source to let AI Agents answer questions using your published Atlas articles.

Unlike external sources, Atlas does not require any authentication or external connection. You can directly control **what parts of your Atlas content get indexed** using categories and URL rules.

## Adding Atlas as a Knowledge Source

To add Atlas:

1. Go to **AI Agents → Knowledge Sources**
2. Click **Add Knowledge Source**
3. Choose **Atlas**
4. Configure the options below
5. Click **Add**

### Configuration Options

* Name:  This is only used to identify it inside ClearFeed (for example: *“Public Help Center”* or *“Internal Atlas Docs”*).
* Tags: Add one or more tags to label this Knowledge Source. Tags help you:
  * Organize multiple knowledge sources
  * Filter or group sources inside ClearFeed
  * Understand what this source is used for (for example: `atlas`, `internal`, `product-docs`)
* Categories: Choose which Atlas categories should be indexed:

  * **Index all categories:** All published articles across all Atlas categories will be indexed.
  * **Index specific categories:** Only articles from the selected categories will be indexed.

  Use this when:

  * You want different AI Agents to use different parts of your knowledge base
  * You want to exclude internal or irrelevant categories from AI answersIndex pages where URL

  Only published articles in the selected categories are indexed.
* Index pages where URL: This lets you further **filter which Atlas pages are included** using URL-based conditions. You can:

  * Add one or more conditions
  * Include or exclude pages based on their URL pattern

  If no conditions are added, all pages from the selected categories are indexed.
* Auto Reindex Regularly: When enabled, ClearFeed will automatically reindex this Knowledge Source **once every 24 hours**. This ensures that:
  * Newly published articles are picked up
  * Updates to existing articles are reflected in AI answers
  * Deleted or unpublished content is removed from the index

## What Content Is Indexed

AI Agents will use:

* Published Atlas articles
* Article title, content, and excerpt
* Category and tag context (to improve relevance)

AI Agents will **not** use:

* Draft articles
* Unpublished articles
* Content outside the selected categories or URL rules
