Supercharge your research. Instantly copy, save, and export notes from Google NotebookLM with formatting preserved. 100% Offline & Private.
NotebookLM Saver is a Chrome Extension designed to bridge the gap between Google's AI notebook and your local workflow. It injects a smart "Copy Note" button directly into the NotebookLM interface, allowing you to save insights to a local history vault, export them to PDF/Word, and paste them into other apps without losing bolding, headers, or lists.
- Smart Injection: Automatically detects the NotebookLM footer and injects a seamless "Copy Note" button that fits the native UI design.
- Rich Text Copying: Copies notes to your clipboard in both HTML (for Word/Docs) and Plain Text (for Notepad/Markdown) simultaneously.
- Local History Vault: Every copied note is saved to
chrome.storage.local. It stores up to 500 items with deduplication logic to prevent clutter. - Robust Selectors: Uses a "waterfall" of CSS selectors to find note titles and content, ensuring the extension keeps working even if Google changes the website's code.
- Export Options:
- 📄 PDF: Generates a clean, printable view for saving as PDF.
- 📝 DOC: Exports the note as a
.docfile compatible with Microsoft Word.
- Search & Organize: A popup dashboard lets you search through your saved history by title or content.
