# Knowledge library

The **Knowledge** page in the sidebar is your workspace's knowledge library. It shows everything your experts know: shared **folders**, each expert's **own knowledge**, and every document inside them. Use it to see what each expert reads, find a document, move it to where it belongs, and share knowledge across experts with folders.

Admins add, rename, move, refresh and delete. Members can browse, search, filter and open every document, read-only.

## The library at a glance

The top level lists **folders** first, then one row per **expert** that has knowledge of its own. The top right shows your workspace's knowledge storage against your plan.

| Row        | What it is                                                                   | Who reads it                            |
| ---------- | ---------------------------------------------------------------------------- | --------------------------------------- |
| **Folder** | Knowledge several experts share: company facts, policies, a product catalog. | Every expert the folder is attached to. |
| **Expert** | That expert's own documents.                                                 | Only that expert.                       |

![The Knowledge page with one shared folder and two experts](/_fern-files/_img/57fbd9487601c904aa601f042e41217b5b07bbf171c96e423342507a364ff43a.webp)![The Knowledge page with one shared folder and two experts](/_fern-files/_img/eb6e4091562c42e316159030fb0ec422f58f1c339822246d72d8aee54f0f685b.webp)

Open a folder or an expert to see its documents. The breadcrumb at the top takes you back to **Knowledge**. Each place has its own address, so you can bookmark or share a link to it.

* **Inside a folder**, **Used by** lists the experts that read it. **Attach to experts** changes that list; **Folder actions** (**⋯**) has **Rename folder** and **Delete folder**.
* **Inside an expert**, **Also reads** lists the folders attached to it, and **Open *name*'s Knowledge tab** takes you to the expert's settings.

## Add knowledge

Admins see a row of actions above the list:

| Action            | What it adds                                                                          |
| ----------------- | ------------------------------------------------------------------------------------- |
| **Add website**   | Pages imported from a site. See [Website import](/knowledge/website-import).          |
| **Upload files**  | PDF, Word, Markdown and text files, one at a time or a whole folder.                  |
| **Create text**   | Text you type or paste: prices, policies, product details. Markdown works too.        |
| **Add FAQ**       | Question-and-answer pairs. See [Questions and answers](/knowledge/faqs).              |
| **New folder**    | An empty shared folder, ready for documents. Shown at the top level.                  |
| **Sync websites** | Refreshes every website import here (in this folder, or everywhere at the top level). |

At the top level, each add first asks where it goes in **Add to**: an existing **Folder**, a **New folder**, or an **Expert**. Inside a folder or an expert, it goes there.

## Share knowledge across experts with a folder

#### Create the folder

At the top level, choose **New folder**. Give it a **Name** and, optionally, a **Description**.

#### Add documents

Open the folder and use **Add website**, **Upload files**, **Create text** or **Add FAQ**.

#### Attach it to experts

Choose **Attach to experts**, tick the experts that should know it, and choose **Save**. They read it from their next conversation.

#### Check it

On one of those experts' **Knowledge** tab, the folder now shows under **Shared knowledge**. Ask something only the folder answers in **Try a question**.

You can also attach folders from the expert's side: **Knowledge** tab → **Shared knowledge** → **Choose collections**. Folders and collections are the same thing.

## Find a document

Use the toolbar above the list:

* **Search knowledge…** matches document names, file names and page addresses. It does not search the text inside documents; use **Try a question** on an expert for that.
* **Type**: **File**, **Text**, **Web page** or **Questions**. Pick more than one.
* **Creator**: **Anyone**, or the person who added it.
* **Sort**: **Last updated**, **Name** or **Created**, in either direction.

At the top level, searching or filtering shows matching documents from every folder and expert in one flat list, with a **Location** column. The list shows **Name**, **Location**, **Status**, **Created by** and **Last updated**.

## Open a document

Choose a document to open its panel. It shows:

* where it **Lives in**, its **Size**, who created it and when;
* **Used by**: the experts that read it;
* **What the expert reads**: the text Rydhm extracted from it (the first 20,000 characters for a long document).

From the panel, admins can **Rename**, **Move**, **Edit questions** (for a question-and-answer set), **Retry** (for a document that failed) or **Delete**.

## Move, rename and delete

* **Move to…** sends a document to another folder, a new folder or an expert. The experts that read the new place know it from their next conversation; the ones that read the old place stop.
* **Rename** changes a document's display name, or a folder's name.
* **Delete** removes a document for every expert that reads it. Tick several documents to delete them together.
* **Delete folder** deletes the folder **and all its documents** for every expert that reads it.

Deleting can't be undone.

## Gotchas

* **A document lives in one place.** It belongs to one folder or one expert, never both. To share an expert's document, move it into a folder and attach the folder.
* **A folder with no experts attached isn't read by anyone.** Its **Used by** line says *No expert yet*.
* **Sync websites shares the website-import limit** of 10 imports or refreshes an hour per workspace. Sites past it are left for later, and the confirmation says how many.
* **API keys limited to specific experts** only see those experts' knowledge and the folders they use. See [Scopes](/developers/scopes).
