**Private beta**

Business Knowledge is in private beta. If **Business Knowledge** isn't in your PostHog sidebar, your project isn't in the beta yet. [Send feedback in the app](https://app.posthog.com/#panel=support%3Afeedback%3A%3Alow%3Atrue).

## Add your knowledge

Open [**Business Knowledge**](https://app.posthog.com/business-knowledge) and choose **Add source**. Most teams start with their docs and website. Paste the URL and choose **Sitemap.xml** or **Same-origin crawl**, so PostHog indexes every page instead of one. Set auto-refresh to every day, and new pages show up without you adding them again.

You can also paste a policy as text, or upload a PDF, DOCX, Markdown, CSV, or plain text file.

## Turn on AI data processing

Answers stay empty until two checks pass:

1.  An organization owner or admin approves AI data processing under **AI service providers** in organization settings. Until then, PostHog doesn't send source text to a model, and the Playground refuses questions.
2.  Each document passes the content check. Keyword search works as soon as it does. Semantic search can take up to an hour more, and the source shows **indexing** until it's ready.

## Choose what every reply includes

Turn on **Always include in replies** for guidance that should be in every answer: tone, policies, and company direction. PostHog still runs the content check.

[Set a source to always include](https://posthog.com/docs/business-knowledge/sources.md#always-include-in-replies)

## Connect your GitHub repos

Select the repositories your agents should know about. When document search finds nothing, Business Knowledge looks in those repositories for a matching file and reads it.

**PostHog does not index your repositories**

Your code is **not** indexed, and PostHog doesn't search inside files. Business Knowledge searches file names and README text, then reads the matching file from GitHub when an answer needs it.

Install the [PostHog GitHub App](https://app.posthog.com/settings/project-integrations), then connect it under **GitHub repositories** in [Business Knowledge settings](https://app.posthog.com/business-knowledge/settings).

## See what's covered and what's missing

Use **Chat** to ask a question a customer or teammate would ask. If the answer cites a source, that fact is already in Business Knowledge. If it can't find the fact, add a source and ask again. Use **Search** to see which chunks match a query, without an answer.

[Open the Playground](https://posthog.com/docs/business-knowledge/playground.md)

## Learn from support

Let PostHog add reusable answers from resolved [Support](https://posthog.com/docs/support/start-here.md) tickets. It learns only from public replies your team wrote, never from private notes or AI drafts.

Learning is off until you turn on **Self-learning** in [Business Knowledge settings](https://app.posthog.com/business-knowledge/settings). Support has to be on in that environment first.
