# Knowledge base overview

> Everything the bot knows lives here

The knowledge base is the bot's single source of truth. It never answers from general internet knowledge — only from the sources you've added to the workspace. Better knowledge means better answers.

## Source types

| Source                 | What it is                                                                   | Cost                |
| ---------------------- | ---------------------------------------------------------------------------- | ------------------- |
| **File**               | An uploaded `.md` or `.txt` document                                         | 2 credits           |
| **Web page**           | A single URL, indexed once                                                   | 2 credits           |
| **Documentation site** | A whole docs site (GitBook and similar), crawled page by page                | 15 credits per site |
| **Learned Q\&A**       | Question–answer pairs the bot picked up from your trusted members in Discord | 3 credits per pair  |

Ingestion is charged **per source**, not per page — a 200-page documentation site still costs 15 credits. See [Credits](/billing/credits).

## Processing statuses

Every source moves through these statuses after you add it:

* **Pending** — queued for processing.
* **Processing** — being read and indexed.
* **Ready** — the bot can answer from it.
* **Error** — something went wrong; the error message is shown on the source. Fix the cause (e.g. an unreachable URL) and re-add or reindex it.

## Limits

How many knowledge sources a workspace can hold depends on the plan:

| Plan | Knowledge sources |
| ---- | ----------------- |
| Free | 5                 |
| Pro  | 20                |
| Team | Unlimited         |

Only sources you add yourself count toward the limit — files, web pages, and documentation sites. Learned Q\&A pairs from [auto-learning](/knowledge/auto-learning) are unlimited on every plan.

## Organizing knowledge

* **Tags** — label sources to keep a large knowledge base navigable.
* **Delete** — removing a source immediately removes it from the bot's answers.
* For crawled documentation sites, the dashboard shows the tree of indexed pages so you can see exactly what the bot has read.

<Tip>
  Write knowledge the way you'd answer a member: short, factual, one topic per document. Marketing copy and long unstructured pages produce weaker answers than a clean FAQ.
