Smart NotebookLM Importer EN

Smart NotebookLM Importer helps send web content directly into Google NotebookLM in a faster, cleaner, and more structured way. Based on the extension package, it is built for people who gather information while browsing and want to turn that material into useful NotebookLM sources without repeated manual copying and pasting. The extension supports several import types, including full web pages, highlighted selections, standard links, and YouTube content, making it suitable for research, reading, reference collection, and study workflows.

The extension works through a popup interface, background service worker, and content scripts that coordinate across regular websites and NotebookLM pages. On normal web pages, it can inspect the active tab, detect selected text, gather metadata such as the page title, URL, favicon, preview image, and approximate word count, and determine whether the page is a YouTube link. On NotebookLM pages, it uses a bridge layer to communicate with the NotebookLM interface so it can retrieve available notebooks, create new notebooks, add sources, and provide a notebook link after import completes.

One of its main strengths is content cleanup. The package includes article extraction logic based on readability-style processing and Markdown conversion, showing that it aims to capture the useful body of a page rather than raw HTML. Imported content can include a heading, source URL, author when available, publication or site name when available, and a capture timestamp. For highlighted text, the extension creates a focused Markdown note marked as a captured highlight, again preserving source details and timing information. This helps keep imported material easier to review later inside NotebookLM.

The extension also adds context menu shortcuts for sending a selection, sending a clean page, and sending a link. These actions allow quick importing without opening the popup each time. The popup itself appears to support notebook selection and notebook creation, with controls such as Create New Notebook, Add to Notebook, and Open Notebook. It can fetch notebook lists, show page details, and return the destination notebook URL after a successful import. The package also indicates login checks, status handling, retry behavior for some source actions, and a clipboard fallback when direct insertion is limited, helping maintain usability across different NotebookLM states.

Key Features:
- Imports content directly into Google NotebookLM from the popup, background workflow, and context menu actions.
- Supports multiple source types, including clean web pages, selected text highlights, links, and YouTube content.
- Uses readability-style extraction and Markdown conversion to produce cleaner, more structured page imports.
- Preserves metadata such as title, source URL, author, publication or site name, and capture timestamp when available.
- Lets you choose an existing NotebookLM notebook or create a new notebook during the import process.
- Checks NotebookLM sign-in state, retrieves notebook lists, and can open the destination notebook after import.
- Includes fallback behavior that can copy prepared content for manual pasting when direct NotebookLM insertion is not available.

How It Works:
1. Open a web page, article, link, or YouTube page you want to send to NotebookLM.
2. Use the extension popup or a context menu action to choose whether to import a clean page, a selection, or a link.
3. The extension analyzes the active tab, gathers available metadata, and detects whether selected text or YouTube content is present.
4. For page imports, it extracts the readable content and converts it into structured Markdown with optional metadata details.
5. The extension connects to Google NotebookLM, checks sign-in state, and retrieves available notebooks or lets you create a new one.
6. It sends the prepared content or source link into the chosen NotebookLM notebook and returns success information when available.
7. If direct insertion is limited, it can fall back to copying the prepared content so you can paste it into NotebookLM manually.

Privacy: - This extension uses browser permissions such as active tab access, tabs, storage, context menus, scripting, and host access to NotebookLM and visited pages in order to extract content and send it to Google NotebookLM. The package contents do not include a privacy policy file, and no explicit statement saying that no personal data is collected is present in the extension files.
