Mass delete sources in NotebookLM. Streamline your Google NotebookLM workflow by deleting multiple sources at once. Instead of manually removing sources one by one through multi-click menus, Bulk Delete Sources for NotebookLM adds a simple batch management tool directly into your NotebookLM interface. Key Features: • Easy Selection: Check individual files, use "Select All", or "Clear" selections in a single click. • Safe Deletion Order: Processes items from bottom to top to preserve list indices and prevent misclicks. • Continuous Verification: Ensures a source is completely deleted and the list is stable before moving to the next item. • Identity & Inventory Safety: Tracks duplicate file names accurately and performs inventory reconciliation checks throughout the process. • Automatic Safety Stop: Halts execution immediately if an unexpected UI change or network ambiguity occurs. How to Use: 1. Open any notebook on notebook.google.com. 2. Click the red "Mass delete sources" button above your sources list. 3. Select the sources you want to remove. 4. Click "Confirm Delete" and let the extension safely process the batch. Note: This is an independent utility designed to enhance NotebookLM workflows and is not affiliated with Google.
