# Connected Sources

> Sync folders from Google Drive, SharePoint and OneDrive, Confluence and Notion, watch each sync as it runs, and see what every document changed.

Category: Knowledge Center

## Overview

Connected sources keep the folders where your team already writes in sync with the Knowledge Center. Pick the folders, spaces or pages once, and Grow reads every document in them, keeps each one in the Library, and checks again for changes on its own.

You can connect **Google Drive**, **SharePoint and OneDrive**, **Confluence** and **Notion**. Access is read-only: nothing is ever changed or deleted at the source.

> **Your knowledge only changes when you say so**
> 
> Synced documents are always searchable in the Library, so Grow uses them when it writes. Your company knowledge fields change only through updates you review. When a document you already synced changes, it is read again and the changes come to you for review, unless **Propose updates from changed files** is off.

## How to connect a folder

1.  **Open Sources**Go to Knowledge Center, then **Sources**. Click **Connect a source** and pick one. You can also click **Add knowledge** and choose **Connect a folder**.
2.  **Sign in**For Google Drive click **Continue with Google**, for SharePoint and OneDrive **Continue with Microsoft**. For Confluence and Notion, sign in with the provider, or open **Other ways to connect** and paste a token.
3.  **Pick what to sync**In **Folders** (**Spaces** for Confluence, **Pages** for Notion), tick a folder to include everything inside it. Use the arrow to open a folder and pick single files instead.
4.  **Save and watch it run**Click **Save and sync**. The window stays open and shows the sync as it happens: looking for files, which document it is reading, and how many are done.

> **Already connected?**

> A connected source stays in **Connect a source**, marked connected. Open it to add folders or to see its files.

## See what each document did

The **Files** view lists every synced document. Click a document's name to open the original in a new tab. Under the name you see when it was read, or why it could not be read. On the right you see what it did to your knowledge:

### In Library

Grow searches the document when it writes. Your knowledge did not change, because the document is new, has not changed since, or proposed updates are off.

### Finding changes

Grow is reading the document and comparing it with your knowledge.

### Review changes

The document suggests updates. Click the button to review them, keep what is right and discard the rest.

### Updated facts

Updates from this document were applied. Point at it to see which fields changed.

### Failed or Skipped

The document could not be read, or its format or size is not supported. The reason is shown under its name; a failed document is tried again on the next sync.

Sources check for changes on their own every few hours. Click **Sync now** to check straight away.

## Proposed updates

A synced document that changes is read for facts about your company, and the changes come to you for review. The review marks a change as a conflict when it disagrees with what is saved, such as a new price, when two of your documents disagree, or when someone edited the field by hand. It also lists facts the new version no longer states as **Possibly outdated**, so you can edit or remove them. When a file is deleted at its source or from the Library, the facts only that file taught open a review of their own, also marked **Possibly outdated**. Check them, change what is no longer true, then click **Mark as checked**. In **Folders**, switch on **Propose updates from changed files** to have new documents read for facts too, or switch it off to keep every document in the Library only.

> Reading a document for changes uses Grow Credits. Keeping it in the Library only uses a small amount.

## Good to know

-   Google Drive reads Docs, Sheets, Slides, PDFs and Office files. SharePoint and OneDrive read PDFs and Office files. Confluence reads pages, Notion reads pages and databases.
-   In Notion, share each page or database with the integration, or it cannot be read.
-   Long PDFs, including scanned ones, are read too; very long files take longer.
-   Click Disconnect to stop syncing. Files already in the Library stay unless you choose to remove them.
