# Knowledge

Your bot answers from the content you give it. Each place that content comes from is a **data source**: a website, uploaded files, Notion pages, YouTube videos, RSS feeds or text you write in Chat Thing. Add data sources, keep them in sync as your content changes, and tune how your bot searches them.

## Most common tasks

- [Add, sync or delete a data source](https://chatthing.ai/docs/knowledge/manage-data-sources)
- [Add your website](https://chatthing.ai/docs/knowledge/website)
- [Upload files](https://chatthing.ai/docs/knowledge/files)
- [Connect Notion](https://chatthing.ai/docs/knowledge/notion)
- [Keep your bot's knowledge up to date](https://chatthing.ai/docs/knowledge/keep-it-up-to-date)
- [Fix answers the bot can't find](https://chatthing.ai/docs/knowledge/retrieval-settings)

## In this section

- [Add, sync and delete data sources](https://chatthing.ai/docs/knowledge/manage-data-sources): Add a data source to your bot, sync it, re-sync after changes and delete it, plus how many data sources each plan allows and per-type limits.
- [Add your website](https://chatthing.ai/docs/knowledge/website): Add pages from your website to your bot by URL, sitemap or crawl, choose which part of each page is read, and access password-protected sites.
- [Upload files](https://chatthing.ai/docs/knowledge/files): Upload PDFs, Word documents, CSVs, Markdown, HTML, JSON, EPUB, text and zip files to give your bot knowledge from your documents.
- [Connect Notion](https://chatthing.ai/docs/knowledge/notion): Connect your Notion workspace and add pages or databases so your bot can answer from your wiki, handbook or knowledge base.
- [Add YouTube videos](https://chatthing.ai/docs/knowledge/youtube): Add YouTube videos or whole playlists so your bot can answer questions from their English captions, such as tutorials and product demos.
- [Add an RSS feed](https://chatthing.ai/docs/knowledge/rss): Add an RSS feed so your bot learns from your blog, news or changelog, including the full pages each feed item links to.
- [Add content manually](https://chatthing.ai/docs/knowledge/manual): Write or paste content directly into Chat Thing to fill gaps in your knowledge, such as FAQs, policies or details that aren't published anywhere.
- [Keep your bot's knowledge up to date](https://chatthing.ai/docs/knowledge/keep-it-up-to-date): Re-sync data sources by hand, on a daily, weekly or monthly schedule, or automatically when you publish in your CMS, and see what each sync changes.
- [Structure your content for better answers](https://chatthing.ai/docs/knowledge/best-practices): Split data sources sensibly, pick the right CSS selectors for your CMS, and write content your bot can find and quote accurately.
- [Retrieval settings](https://chatthing.ai/docs/knowledge/retrieval-settings): Control how much of your knowledge your bot reads for each message - document relevance, context documents, enhanced retrieval, sources and chunk size.
