NotebookLM Enhancer

An enhancer for NotebookLM, providing folder management, advanced search and more.

Unlock the full potential of Google NotebookLM with the NotebookLM Directory Manager! Say goodbye to cluttered, flat document lists and hello to a structured, highly efficient knowledge management experience. 🌟 Core Features 1. Structured Directory System (Tree View Management) Seamlessly create, rename, and manage custom folders. Easily categorize your documents using dropdown menus or drag-and-drop. Automatically isolates unassigned documents into an "Uncategorized" section to keep your workspace tidy. Multi-selection support: Check a folder to automatically select all its nested source documents for quick batch processing. 2. Advanced Floating Search A modern, frosted-glass floating search panel that doesn't waste precious vertical space. Supports advanced logical filtering (e.g., using "space" for OR, "+" for AND). Intelligently hides empty folders and categories when searching, keeping the view clean. Perfect support for IME (Input Method Editors, e.g., Pinyin for Chinese). 3. Native UI Integration & Responsive Design Deeply integrated with Google's Material Design, feeling like a built-in feature. Automatic Light/Dark theme switching based on native NotebookLM settings. Adaptive panel width that smoothly follows your sidebar resizing. 4. Performance & Security High-performance DOM manipulation using secure methods (CSP-compliant). Completely local processing: The extension only modifies the UI on your client side and NEVER uploads, reads, or interferes with your actual note data contents. Disclaimer: This extension is an independent tool developed to improve productivity and has no affiliation, sponsorship, or partnership with Google LLC or official NotebookLM. 🚀 **What's New in v1.1.7.4** - **Bug Fix**: Fixed an issue where the extension's search box would incorrectly remain visible on the screen when opening and reading a specific Note (Mini/Standby mode). Enjoy a cleaner and distraction-free reading experience! 🚀 **What's New in v1.1.7.5** - **Bug Fix**: Auto-Refresh: Fixed an issue where newly imported sources wouldn't appear immediately in the sidebar; updated MutationObserver for real-time UI synchronization. Smart Visibility: Resolved the persistent visibility of the extension icon in Note views and maximized Studio artifacts (Slide Decks, Mind Maps, etc.). View Detection Stability: Refined the sidebar detection logic using a strict triple-condition rule (source-panel-view-content, aria-modal, and panel-collapsed) to ensure the toolbar perfectly matches the native NotebookLM layout states. What's New in Version 1.8.0 (Purification Release) 1. Now Fully Free & Open-Source! We have completely removed all Gumroad-related purchase, activation, and license verification logic. NotebookLM Enhancer is now a 100% free, open-source tool dedicated to the community. No more activation keys or "Pro" popups—just pure productivity. 2. Visual "Purification" The user interface has been significantly decluttered. We've removed the license activation panel, purchase buttons, Gemini API settings, and version labels. Enjoy a minimalist, native-like experience that blends perfectly with NotebookLM. 3. Intelligent Search Auto-Reset Fixed a navigation bug: search queries and the floating search panel will now automatically reset when you switch between different notebooks, ensuring a fresh start for each project. 4. Optimized Sidebar Stability Refined the container management and observer logic to ensure the enhanced directory tree stays perfectly aligned, even during heavy multitasking in the NotebookLM sidebar.
