This guide explains how to use the Extract from Link feature to import web pages or Feishu / Lark cloud documents into your AI assistant’s knowledge base.
Quick Summary: Copy a Feishu document or wiki link → paste it into the Extract from Link dialog → click Add. The system will automatically crawl and add the content so the AI can reference it.

​
Entry Point

On the AI assistant’s Knowledge Base edit page, click Extract from Link. A dialog appears:
  • Title: Extract from Link
  • Supported: web links, Feishu / Lark cloud document links
  • Input: paste the target link
  • Hint at bottom: Feishu / Lark wiki links extract up to 1000 documents

​
Knowledge Base Capacity Limits

Per-assistant knowledge base limits (apply to both Extract from Link and Upload File):

​
Unsupported Content

The following link types cannot be imported; please use file upload or another method:
  • WeChat Public Account articles (mp.weixin.qq.com): not supported by the crawler; blocked on submission
  • Feishu / Lark Slides: only native Slides created in Feishu / Lark (links likeslides/...) are unsupported
To import a native Slide created in Feishu / Lark, either copy its content to a regular Feishu / Lark cloud doc (docx) first, or export it as a local file (.pptx) and upload it into Feishu / Lark, then import via its file link.

​
How to Import a Single Feishu / Lark Cloud Document

1

Open the document

Open the target Feishu / Lark native document or uploaded file cloud document in your browser.
2

Copy the URL

Copy the full URL from the address bar (e.g. https://xxx.feishu.cn/docx/... for a native doc, or https://xxx.feishu.cn/file/... for a file cloud document).
3

Open Extract from Link

In AnyGen, open the AI assistant’s Knowledge Base → click Extract from Link.
4

Paste the link

Paste the link into the input box.
5

Click Add

Click Add. The content is added to the assistant’s knowledge; the AI will reference it automatically.

​
How to Import a Feishu / Lark Wiki

Two methods, choose based on your use case: Use this when you want to import a single wiki node as a knowledge document.
1

Open the wiki

Open the target wiki in Feishu.
2

Find the node

Find the node you want to import.
3

Copy the node link

Copy that node’s link (e.g. https://xxx.feishu.cn/wiki/...).
4

Paste and add

Paste it into the Extract from Link dialog, click Add.
5

Single node only

The system crawls only this node — it does not recurse into descendants. To import the entire wiki, use Method 2.

​
Method 2: Global Wiki Import (up to 1000)

Use this when you want to import an entire wiki from the root in one go.
1

Open the wiki

Open the target wiki in Feishu.
2

Click Share Wiki

Click Share Wiki in the lower-left.

3

4

Paste and add

Paste it into Extract from Link, click Add.
5

Bulk crawl

The system detects it as a global wiki link and crawls all documents, up to 1000.

​
Permissions (Important)

Access rules differ by link type:
  • Feishu document / Base / wiki: access inherits from the current signed-in user’s Feishu read permission. If you can open the link in Feishu, AnyGen can crawl it — no public-link setting is required.
  • Generic web page: must be publicly accessible without login. Pages that require login, are behind a paywall, or are intranet-only cannot be crawled.
Import failures are usually caused by one of these conditions not being met.
  1. Confirm the Feishu account currently signed in to AnyGen can open the target document / wiki in Feishu.
  2. If you can’t open it, request read access from the document / wiki owner.
  3. Once you can open it, copy the link and paste it into the Extract from Link dialog.
Wiki child node permissions: when bulk-importing via the global link (Method 2), check in Wiki Settings → Permission Management that all child nodes you need imported are readable by the current user. If only some sub-documents are crawled, it is usually because child nodes did not inherit the permission.

​
FAQ

The most common cause is insufficient permission: Feishu content requires the current signed-in user to have Feishu read access; generic web pages must be openable without login.Investigation order:
  1. Can you open it in Feishu? Open the link in your browser with the same Feishu account currently signed in to AnyGen and confirm you can read it.
  2. Child-node permission (global link / Method 2 only): see the wiki child-node permission note under Permissions above.
  3. Link type: confirm it’s not a WeChat article, or a native Feishu / Lark Slide (created in Feishu / Lark).
  4. Network reachability: for web links, confirm the page is reachable on the public Internet (not an intranet-only domain).
A global share link (my.feishu.cn/wiki/space/...) imports up to 1000 documents per call. If your wiki exceeds 1000 documents, suggestions:
  • Split the content into multiple sub-wikis, generate a global share link for each, and import them one by one.
  • Or pick the 1000 most-referenced documents, organize them into a new wiki, and import that.
Pages that rely on JavaScript rendering (SPAs, login-required, paywalled) are unreliable. Suggestions:
  • Copy the content into a Feishu cloud doc first, then import via the Feishu link.
  • Or directly upload a PDF / Word / Markdown file.
Feishu Docs, Sheets, and Base all support an Auto Sync option. On the assistant’s Knowledge Base page, find the Auto Sync config and turn it on — the system will periodically re-crawl the latest content.
Yes. An uploaded file is stored as a file cloud document (/file/... link) and can be imported via Extract from Link. This differs from a native cloud document Slide created directly in Feishu / Lark, which is not supported — see Unsupported Content above.
