NoteJet

NoteJet is a Chrome extension that sends the current page into NotebookLM with fewer manual steps.

Before you start

• Node.js 20+ (required for node --test, used as primary runtime)
• npm (all build scripts use npm run)
• TypeScript (installed via npm as devDependency)
• Bun is optional — used only for formatting convenience (bunx --bun @biomejs/biome format --write). You can also use npx @biomejs/biome format --write instead.
• Make sure you can sign in to NotebookLM in Chrome.

Install the extension

1. Run npm install.
2. Run npm run build.

Build sub-commands for reference:

• npm run clean — remove dist/
• npm run build:ts — TypeScript compile only
• npm run build:assets — copy static assets only
• npm run build — full build (clean + ts + assets)

3. Open chrome://extensions in Chrome.
4. Turn on Developer mode.
5. Click Load unpacked.
6. Select the dist/ folder.

Development

• Test: npm test builds the project then runs the Node.js test runner. Tests are .mjs files in tests/ and cover shared modules (API client, auth, session state, URL policy, YouTube channel parsing).
• Format: npm run format:fix (uses Biome). Or bun run format:fix if you prefer Bun.
• Lint: no ESLint or TypeScript strict mode is currently configured.
• Reload: After changes, run npm run build then click Reload on the extension card in chrome://extensions.

What NoteJet does

• Captures the title and URL of the current tab.
• Shows recent notebooks and lets you search existing notebooks.
• Lets you create a new notebook.
• Imports the current page URL into the selected notebook.
• Lists videos from a YouTube channel profile and imports selected videos one by one.
• Checks whether the current page is allowed by your import whitelist.

How it works

NoteJet uses a dual approach to import pages:

• API-first: it tries NotebookLM's internal RPC API (batchexecute endpoint) using Google cookie auth (SID, __Secure-1PSID, __Secure-3PSID cookies)
• DOM fallback: if API calls fail, it falls back to automating the NotebookLM web UI via the content script

Basic workflow

1. Open the webpage you want to save.
2. Open the NoteJet popup.
3. Check the captured page title and source URL.
4. Confirm the source is allowed by the whitelist.
5. Search for a notebook or create a new one.
6. Select a notebook.
7. Click Import.

If the import succeeds, the popup will show a success message.

Import YouTube channel videos

YouTube channel import only appears when the current tab is a YouTube channel profile, such as:

• https://www.youtube.com/channel/UCX6OQ3DkcsbYNE6H8uQQuVA
• https://www.youtube.com/@MrBeast

Before using it, open Edit import whitelist and add a YouTube Data API key. Google's setup guide is linked from the options page: https://developers.google.com/youtube/v3/getting-started

Workflow:

1. Open a YouTube channel profile.
2. Open the NoteJet popup.
3. Select or create the NotebookLM notebook.
4. Click Import YouTube channel.
5. Search or scroll the video list.
6. Check the videos to import.
7. Click Import selected videos.

NoteJet imports selected videos sequentially. If one video fails, the batch continues and the popup reports the imported and failed counts.

Sign in to NotebookLM

NoteJet needs an active NotebookLM session before it can search notebooks, create notebooks, or import URLs.

If you are not signed in:

• the popup will show NotebookLM login expired. Please sign in again.
• the main actions will stay disabled
• the link at the bottom will change to Sign in to NotebookLM

Click that link to open NotebookLM and sign in, then return to the popup and click Refresh session.

Manage the import whitelist

Click Edit import whitelist in the popup to open the options page.

The whitelist supports these formats:

• * to allow all HTTP and HTTPS websites
• example.com to allow one exact host
• *.example.com to allow subdomains
• https://example.com to allow one host with a specific scheme

Rules to know:

• only HTTP and HTTPS pages can be imported
• browser pages such as chrome:// and local files are blocked
• if the current page is not allowed, the popup will show a message and the import button will stay disabled

Create a new notebook

1. Open the popup.
2. Type a notebook name in New notebook name.
3. Click Create.
4. Wait for the success message.

The new notebook should appear in the notebook list and become the selected target.

Open a notebook manually

Use the link at the bottom of the popup to open the selected notebook in a new tab.

If no notebook is selected, the link stays hidden. If you are signed out, the link opens the NotebookLM home page instead.

Privacy and local data

NoteJet stores local extension data to keep the workflow usable between sessions.

This includes:

• recent notebook entries
• import whitelist settings
• YouTube Data API key
• NotebookLM session state
