# Knowledge overview

**Knowledge** is the material an expert answers from. Give an expert your price list, your policies, your website and the questions you hear most, and it answers from them. When something isn't there, it says so instead of making it up.

## What you can add

| Kind                      | What it is                                                     | How to add it                                                   |
| ------------------------- | -------------------------------------------------------------- | --------------------------------------------------------------- |
| **Files**                 | PDF, Word (.docx), Markdown, text and CSV, up to 8 MB each     | Upload or drop them, one at a time or a whole folder            |
| **Text**                  | Anything you type or paste: prices, policies, product details  | **Paste text** (expert tab) or **Create text** (Knowledge page) |
| **Web pages**             | Pages read from your website, kept up to date when you refresh | [Website import](/knowledge/website-import)                     |
| **Questions and answers** | The questions you hear most, each with your answer             | [Questions and answers](/knowledge/faqs)                        |

> **Tip**
>
> Markdown with clear headings gives the most accurate answers. Markdown written in the Open Knowledge Format works especially well; when you upload a whole folder of it, its `index.md` and `log.md` files are skipped.

## Where knowledge lives

Every document lives in exactly one place:

* **An expert's own knowledge.** Only that expert reads it. You manage it on the expert's **Knowledge** tab.
* **A shared folder.** Every expert the folder is attached to reads it. Put company facts, policies or a product catalog here once, instead of copying them into each expert.

The **Knowledge** page in the sidebar shows both in one place: every folder, every expert's own knowledge, and every document. See [Knowledge library](/knowledge/library).

> **Note**
>
> On an expert's Knowledge tab, shared folders appear under **Shared knowledge** and are called **collections**. A collection there and a folder in the Knowledge library are the same thing.

## Add knowledge to an expert

#### Open the Knowledge tab

Open the expert and choose **Knowledge**. The top line shows **Knowledge used**: your workspace's total against your plan.

#### Add documents

Choose **Add**: **Upload files**, **Paste text**, **Add from a website** or **Add questions and answers**. You can also drop files on the list.

#### Wait for Ready

Each document shows **Processing** while it is read, then **Ready**. If one shows **Failed**, the reason is beside it; choose **Retry**.

#### Attach shared knowledge (optional)

Under **Shared knowledge**, choose **Choose collections**, tick the folders this expert should know, and **Save**. **New collection** creates one in place.

#### Check it

Under **Try a question**, type something a customer might ask and choose **Search**. See [Search and sources](/knowledge/search).

Knowledge saves as you add it. It doesn't wait for the expert's **Save changes**, and the expert uses it from its next conversation.

## How an expert uses its knowledge

Rydhm picks the approach for you, by size:

* **Small knowledge** (most experts) goes into the expert's instructions whole. On a call, the expert knows all of it on every turn, with no time spent looking things up.
* **Large knowledge** is searched for each question. Rydhm finds the most relevant passages, from the expert's own documents and its folders, and gives them to the model with the question.
* **Text chat** always searches, and shows the documents it used under the reply as **Sources**.

Either way the expert is told to answer from what it found, and to say plainly when the answer isn't there. See [Search and sources](/knowledge/search).

## Limits

* **Size.** Your plan caps the text stored across the whole workspace: experts and folders together. The bar turns amber past 80% and red at the limit. Once billing is switched on for your workspace, anything that would go past the limit is refused: remove something or upgrade. See [Billing](/workspace/billing).
* **Files.** Up to 8 MB per file.
* **Website imports.** A page cap per import, by plan. See [Website import](/knowledge/website-import#limits).
* **Questions and answers.** Up to 500 per document. See [Questions and answers](/knowledge/faqs).

## Who can change it

Admins add, edit, retry and remove knowledge. Members see the same lists, states and search, read-only.

## Gotchas

* **Removing knowledge takes effect from the next conversation.** A call in progress keeps what it started with.
* **Knowledge isn't part of an expert's versions.** Restoring an older version doesn't bring back deleted documents. See [Versions and testing](/experts/versions).
* **Exports don't carry knowledge.** An expert imported from JSON starts with none.
* **Deleting a folder deletes its documents** for every expert that reads it.
