> **Key takeaways**
>
> * In the Beav knowledge base, click **+** next to **Knowledge Base** and choose **Add link**. Paste a single post's link or its share text, without choosing a platform. Beav resolves short links, detects the platform and saves it to the current space.
> * Supported: WeChat Official Account articles, Xiaohongshu (RedNote), Douyin, Bilibili, X, Weibo, Zhihu and recognizable WeChat Channels links. WeChat articles are read by a local parser. The others go through the capture service, which needs sign-in or a configured capture API and consumes quota according to its rules.
> * Content already in the knowledge base is not saved twice. Tick **Break down into assets after saving** to queue a breakdown automatically.

Reference material arrives from everywhere: a Douyin video a friend sent, an Official Account article in a group chat, a RedNote post, a Weibo thread. One downloader per platform means one more tool each time, and the results end up in separate folders.

Beav's **Add link** is a single box. Paste the link, and Beav works out the platform and how to read it, then files it in one knowledge base.

## Who it is for

* Creators who collect from several platforms and do not want a separate tool for each.
* Anyone sitting on links in chats, spreadsheets or bookmarks who wants them in a material library.
* People who would rather paste a link than open the original page in a desktop browser.

## How to use it

![Add link in three steps: click + next to Knowledge Base and choose Add link, paste a link, save and paste the next](https://beav.pro/blog/features/save-any-link-to-knowledge-base-steps-en.webp)

*Click +, choose Add link, paste, save.*

1. **Open the entry.** At the knowledge base root or in a personal folder, click **+** in the title bar or next to **Knowledge Base** on the left, and choose **Add link**.
2. **Paste one link.** A single post, article or video. Share text is fine, and you do not choose a platform.
3. **Tick Break down into assets after saving if you want it.** It is off by default. When ticked, a successful save goes straight into the breakdown queue, which uses models and consumes quota.
4. **Save.** Click **Save** or press Enter. The dialog shows the detected platform and clears, so you can paste the next link. Links are saved one at a time.
5. **Handle failures.** If saving fails, the dialog keeps the link and shows the reason; fix it and save again. Profile links and unsupported URLs are reported right away.

![What happens after pasting: WeChat articles are read locally, other platforms go through the capture service and use quota, duplicates are skipped, and breakdown is optional](https://beav.pro/blog/features/save-any-link-to-knowledge-base-routes-en.webp)

*Different platforms are read in different ways, and everything lands in one knowledge base.*

**What uses quota?** WeChat Official Account articles (`mp.weixin.qq.com`) are read by the app's built-in parser, with no capture API or sign-in. Xiaohongshu, Douyin, Bilibili, X, Weibo, Zhihu and WeChat Channels links are read through the capture service, which requires sign-in or a configured capture API and consumes quota according to its rules.

## How it compares with one downloader per platform

|                            | A separate downloader or mini app per platform | Beav Add link                                                                         |
| -------------------------- | ---------------------------------------------- | ------------------------------------------------------------------------------------- |
| Entry point                | One tool per platform                          | One box that detects the platform                                                     |
| What you keep              | Mostly video or image files                    | A knowledge base entry: text, media and source link                                   |
| Short links and share text | Depends on the tool                            | Short links resolved; share text can be pasted as is                                  |
| Duplicates                 | Often downloaded again                         | Content already saved is not saved twice                                              |
| What comes next            | Organize the files yourself                    | Optional automatic breakdown; the AI can cite it when you write                       |
| Cost                       | Depends on the tool                            | WeChat articles parsed locally; other platforms use the capture service and its quota |

Single-platform downloaders are focused. When you only want one video file, or a feature unique to one platform, they are often the more direct choice. Add link is built for collecting: links from many sources, and you want more than a file, namely something you can find, break down and cite later.

## Limits and notes

* **One single post at a time.** Profile links are not supported, and it is not a bulk import. To submit many links at once, use the QR-code link submission in [phone and computer pairing](https://beav.pro/en/blog/tutorials/beav-phone-computer-transfer). To download media files from mixed-platform links in batches, see [batch download links from multiple platforms](https://beav.pro/en/blog/features/batch-download-links-from-multiple-platforms).
* **Douyin means videos.** Douyin photo sets are not supported.
* Saves go to the root of the current space's knowledge base. The entry is not shown in shared spaces, account profiles, subscription views or local source folders.
* What can be read depends on the platform, the capture service, account permissions and quota. Saved content is for your own research; ask the author before republishing or commercial use.
