NotebookLM Source

NotebookLM Source is a browser extension for faster NotebookLM source preparation. It lets users import links in bulk, parse links from web pages, RSS feeds, and YouTube playlists, and optionally read URLs/titles from current browser tabs when users grant tabs permission. It also supports optional Discord chat export with a user-provided Discord Bot token, exporting selected channel messages to CSV or JSON for user download. The extension uses secure browser-based sign-in for NotebookLM Source accounts and requests sensitive permissions only for core, user-initiated features.
