**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.

## ✨ Key Features



* **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 `.doc` file compatible with Microsoft Word.

* **Search & Organize**: A popup dashboard lets you search through your saved history by title or content.

## 🏗 Project Structure



* **`manifest.json`**: The configuration file. Defines permissions (`storage`, `clipboardWrite`) and scripts.

* **`content_script.js`**: The logic that runs on `notebooklm.google.com`.

    * *Key Function*: `injectButton()` adds the UI element.

    * *Key Function*: `findContent()` scrapes the text using multiple fallback selectors.

* **`background.js`**: A service worker that handles opening the full-page "View" tab.

* **`popup.js` / `.html`**: The small window that appears when clicking the extension icon. Handles the search and list rendering.

* **`view.js` / `.html`**: The full-page read mode. Contains the logic for generating blobs for file downloads.

## 🔒 Privacy & Permissions



This extension is built with a **Local-First** philosophy.



* **`storage`**: Used solely to save your note history on your own device (`chrome.storage.local`). No data is sent to the cloud.

* **`clipboardWrite`**: Required to place the rich text content into your system clipboard.

* **`scripting`**: Used to inject the button and scrape the specific note text when you ask for it.

* **Host Permissions**: The extension is strictly scoped to run only on `notebooklm.google.com` (Note: Ensure your `manifest.json` reflects this for security).
