What it can do

One icon, covering “read · save · watch”

Click the NoteLoom icon in your toolbar, and three actions pull what you read and watch into your local knowledge base — no account, no cloud.

Reading View

Extract the main text of any web page in one click, with an outline generated automatically. Choose from light / sepia / dark themes, three font sizes, and adjustable font and line width; click images to enlarge, and ads and pop-ups are stripped away. Read it over the current page or in a side drawer, and toggle it instantly with Alt+R.

Clip to NoteLoom

Clip web content into Markdown together with its source link and formatting. Preview it in NoteLoom first, then pick a local folder to save it — what you clip becomes a real .md file on your disk. Pages like Xiaohongshu are supported too.

YouTube · Bilibili subtitles

On a video page it automatically switches to subtitle mode: it extracts subtitles and intelligently splits them by 30 seconds or by chapter, click a timestamp to jump straight to that point in the video, with read-along highlighting and auto-scroll during playback, plus full-text search and language switching. Bilibili's AI subtitles and multi-part videos are handled too.

Local-first · No account required

Everything is processed locally in your browser, only when you take action — nothing is uploaded to a server, and no NoteLoom account login is needed. Subtitle fetching uses same-origin requests, and clipped content goes into the local folder you authorized — the same principles as the NoteLoom web app.

Permissions & privacy

Content is processed locally, never sent to ad platforms or data brokers
No account passwords stored, no payment info or verification codes read
Clipped content goes only into the local folder you authorized
Uninstall or clear the extension's data from your browser anytime

FAQ

Questions you might have about the extension

What is the NoteLoom browser extension?
The NoteLoom browser extension is NoteLoom's browser companion. It turns any web page into a clean reading view, and clips web content along with YouTube and Bilibili subtitles into Markdown notes saved in your local NoteLoom knowledge base. It's local-first, zero-server, and doesn't require an account.
Does the extension upload my browsing data?
No. The extension only processes the content of the current page, and only when you actively click the icon, open the reading view, clip a page, or extract subtitles — and it does all of this locally in your browser. It does not upload page text to ad platforms or data brokers, and it does not read everything you browse when you haven't triggered a feature. See the Privacy Policy for details.
Which browsers are supported?
The extension is built on the Chrome extension standard (Manifest V3), so you can install it on Chromium-based browsers like Chrome, Edge, and Arc.
Where is the clipped content saved?
After clipping, the content is first previewed inside NoteLoom, and you choose a local folder (drive) to save it as a .md file. The file lives on your own disk and never passes through NoteLoom's servers.
Which video sites' subtitles are supported?
Currently YouTube and Bilibili are supported. The extension automatically extracts subtitles and splits them by paragraph / chapter; click a timestamp to jump to the matching point in the video. It also supports read-along highlighting, full-text search, and switching between languages, making it easy to turn video content into notes.
Do I need to register a NoteLoom account first?
No account registration is needed. Just authorize a local folder in the web app and you can start saving content to your own knowledge base.
