NotebookLM Antigravity Skill

An Agent Skill for Google Antigravity that provides seamless integration with Google NotebookLM through the nlm command-line interface.

Overview

This skill enables you to use Google NotebookLM directly within Antigravity for:

• Creating and managing notebooks
• Adding sources from URLs, files, text, and Google Drive
• Generating AI-powered audio podcasts and video content
• Performing web research
• Querying notebooks with natural language
• Sharing and collaborating on notebooks

Installation in Antigravity

Option 1: Global Installation (Available Across All Projects)

Clone or copy this skill to:

~/.gemini/antigravity/skills/notebooklm/

Option 2: Workspace Installation (Project-Specific)

Clone or copy this skill to your project's skill directory:

<your-project>/.agent/skills/notebooklm/

First-Time Setup

Step 1: Run the Installation Script

The skill includes an installation script that sets up the nlm CLI:

cd <skill-directory>
bash scripts/install.sh

This will:

1. Check for uv (recommended), pipx, or pip
2. Install notebooklm-mcp-cli package
3. Make the nlm command available in your PATH

Step 2: Authenticate with Google

Before using NotebookLM, authenticate with your Google account:

nlm login

This will:

1. Launch a dedicated Chrome profile
2. Let you log in to Google
3. Automatically extract authentication cookies

Verify authentication:

nlm login --check

Usage in Antigravity

Once installed and authenticated, Antigravity will automatically detect when you want to use NotebookLM based on your request. You can mention tasks like:

• "Create a notebook for my research"
• "Add this URL to my notebook"
• "Generate an audio podcast from these sources"
• "Research [topic] and import sources"
• "What are the key findings in this notebook?"
• "Share this notebook publicly"

Common Workflows

Research + Generate Podcast

1. Antigravity will create a notebook
2. Add sources (URLs, files, Drive docs)
3. Generate an AI audio podcast
4. Download the generated audio

Document Analysis

1. Create a notebook
2. Upload PDF or document
3. Query with natural language
4. Get insights and summaries

Web Research

1. Start research on a topic
2. Automatically find and import top sources
3. Query the gathered sources
4. Generate summary or presentation

Features

Notebook Management

• Create, list, and view notebooks
• Add multiple source types
• Organize research projects

Source Types

• URLs: Web pages, articles
• YouTube: Video transcripts
• Text: Direct text input
• Files: PDF, DOCX, TXT, etc.
• Google Drive: Import Drive documents

AI Content Generation

• Audio Podcasts: AI-generated audio overviews

• Briefings: Summary documents
• Flashcards: Study cards (easy/medium/hard)
• Infographics: Visual summaries
• Mind Maps: Concept visualization
• Slides: Presentation decks

Research & Analysis

• Web research with auto-discovery
• Natural language queries
• Multi-source synthesis
• Drive source sync

Sharing & Collaboration

• Public links
• Invite collaborators (editor/viewer)
• Share management

Requirements

• Antigravity: Google Antigravity installed
• Python Package Manager: uv (recommended), pipx, or pip
• Google Account: For NotebookLM authentication
• Chrome: For authentication (uses headless Chrome)

Limitations

• Rate Limits: Free tier ~50 queries/day
• Auth Expiration: Cookies expire every 2-4 weeks; re-run nlm login
• Internal APIs: Uses undocumented internal APIs (as documented by notebooklm-mcp-cli)
• Use Case: Intended for personal/experimental purposes

Troubleshooting

Installation Issues

# Force reinstall
uv tool install --force notebooklm-mcp-cli

# Or manually
rm -rf ~/.notebooklm-mcp-cli
bash scripts/install.sh

Authentication Failures

# Remove old auth and re-login
rm -rf ~/.notebooklm-mcp-cli
nlm login

Command Not Found

# Check installation
which nlm

# If not found, PATH issue - add to shell config
# For bash/zsh:
echo 'export PATH="$HOME/.local/bin:$PATH"' >> ~/.bashrc
source ~/.bashrc

Studio Content Generation Time

Audio and video generation takes time. Always check status before downloading:

nlm studio status <notebook-id> <artifact-id>

# Wait until status shows "completed", then:
nlm download audio <notebook-id> <artifact-id>

Advanced Usage

Multiple Profiles

Use multiple Google accounts:

nlm login --profile work
nlm login --profile personal
nlm login switch work

uvx (No Install Required)

Run nlm without installing:

uvx --from notebooklm-mcp-cli nlm notebook list
