What is NotebookLM Manager

From the Chrome Web Store

Bulk delete sources in NotebookLM. Remove multiple sources at once — directly from the interface. 11 languages. NotebookLM Manager adds a "Delete selected" button directly into the Google NotebookLM interface, letting you remove multiple sources in bulk — something NotebookLM doesn't support natively.

How it works:

Open any notebook in NotebookLM
Select sources using the existing checkboxes
Click the new "Delete selected (N)" button that appears next to "Add sources"
Confirm in the dialog — done

Features:

Bulk delete any number of sources at once
Button integrates seamlessly into the NotebookLM UI — same style, same font, same height
Automatically updates the count of selected sources in real time
Progress indicator during deletion
Clean confirmation dialog (no browser popups)
Works entirely within the page — no external servers, no data collection
Automatically follows the language set in NotebookLM

Supported languages: 🇬🇧 English · 🇵🇱 Polish · 🇩🇪 German · 🇫🇷 French · 🇪🇸 Spanish · 🇵🇹 Portuguese · 🇯🇵 Japanese · 🇰🇷 Korean · 🇮🇹 Italian · 🇨🇳 Chinese (Simplified) · 🇳🇱 Dutch
