NotebookLM Antigravity Skill

This skill provides seamless integration with Google NotebookLM through the nlm command-line interface. It enables you to create notebooks, add sources from URLs, text, files, or Google Drive, generate AI-powered audio podcasts, perform web research, and query your notebooks with natural language.

Goal

To enable Google NotebookLM functionality within Antigravity for research, content generation, and knowledge management tasks.

Prerequisites

1. Install the tool: Run the installation script before first use
2. Authenticate: You must authenticate with your Google account before using NotebookLM features

Instructions

Step 1: Installation (First Time Only)

Before using NotebookLM, run the installation script to set up the nlm CLI:

bash scripts/install.sh

This will install notebooklm-mcp-cli using uv (recommended) or pip as a fallback.

After installation, verify it's available:

nlm --version

Step 2: Authentication

You must authenticate with your Google account before using NotebookLM:

Auto Mode (Recommended):

nlm login

This launches a dedicated Chrome profile. Log in to Google, and cookies will be extracted automatically.

Check Authentication Status:

nlm login --check

Use Multiple Profiles:

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

Step 3: Common Operations

Once authenticated, you can use any of these commands directly in the terminal:

Notebook Management

# List all notebooks
nlm notebook list

# Create a new notebook
nlm notebook create "Research Project"

# Get notebook details
nlm notebook get <notebook-id>

Add Sources

# Add URL source
nlm source add <notebook-id> --url "https://example.com/article"

# Add YouTube video
nlm source add <notebook-id> --url "https://youtube.com/watch?v=xxx"

# Add text directly
nlm source add <notebook-id> --text "Your text content here"

# Add local file
nlm source add <notebook-id> --file /path/to/file.pdf

# Import from Google Drive
nlm source add <notebook-id> --drive "document-id"

Query Notebooks (AI Chat)

# Ask questions about your notebook
nlm notebook query <notebook-id> "What are the key findings?"

# Generate summary
nlm notebook query <notebook-id> "Summarize all sources"

Generate Audio Podcasts

# Generate audio overview
nlm audio create <notebook-id> --confirm

# Download generated audio
nlm download audio <notebook-id> <artifact-id>

# Download as MP3
nlm download audio <notebook-id> <artifact-id> --format mp3

Generate Other Studio Content

# Generate video explainer
nlm studio create <notebook-id> --type video --style classic

# Generate briefing document
nlm studio create <notebook-id> --type briefing

# Generate flashcards
nlm studio create <notebook-id> --type flashcard --difficulty medium

# Generate infographic
nlm studio create <notebook-id> --type infographic --orientation landscape

# Generate mind map
nlm studio create <notebook-id> --type mindmap

# Generate slide deck
nlm studio create <notebook-id> --type slideshow

Web Research

# Start web research on a topic
nlm research start "enterprise AI ROI metrics"

# Deep research with auto-import
nlm research start "cloud marketplace trends" --deep --import

Share Notebooks

# Make notebook public
nlm share public <notebook-id>

# Disable public access
nlm share disable <notebook-id>

# Invite collaborators
nlm share invite <notebook-id> --email user@example.com --role editor

Sync Google Drive Sources

# Sync all Drive sources
nlm source sync drive <notebook-id>

# Check which sources need sync
nlm source list <notebook-id>

Step 4: Check Studio Content Status

After generating studio content (audio, video, etc.), check the status:

# List all studio artifacts
nlm studio list <notebook-id>

# Get status of specific artifact
nlm studio status <notebook-id> <artifact-id>

Poll the status until it shows "completed", then download using the download command.

Examples

Example 1: Research and Generate Podcast

# Create notebook for research
NOTEBOOK_ID=$(nlm notebook create "AI Research 2026" | grep -oP 'id: \K\S+')

# Add several sources
nlm source add "$NOTEBOOK_ID" --url "https://arxiv.org/abs/2301.07041"
nlm source add "$NOTEBOOK_ID" --url "https://example.com/ai-report"

# Generate audio podcast
nlm audio create "$NOTEBOOK_ID" --confirm

# Wait and download
nlm download audio "$NOTEBOOK_ID" <artifact-id>

Example 2: Quick URL Analysis

# Create notebook, add URL, and query in one flow
NOTEBOOK_ID=$(nlm notebook create "Quick Analysis" | grep -oP 'id: \K\S+')
nlm source add "$NOTEBOOK_ID" --url "https://example.com/article"
nlm notebook query "$NOTEBOOK_ID" "Summarize the main arguments in 3 bullet points"

Example 3: File-Based Research

# Add local PDF and query
nlm notebook create "Document Review"
nlm source add <notebook-id> --file /path/to/report.pdf
nlm notebook query <notebook-id> "What are the key recommendations?"

Example 4: Web Research with Auto-Import

# Research and automatically import top sources
nlm research start "AI agents productivity metrics" --deep --import
# This will create a notebook and import the best sources found

Constraints

IMPORTANT:

• Authentication is required before any NotebookLM operations
• Use nlm login --check to verify authentication status
• Free tier accounts have rate limits (~50 queries/day)
• Cookie-based auth expires every 2-4 weeks; re-run nlm login when prompted
• Always check studio content status before downloading (generation takes time)
• Be mindful of context limits when querying large notebooks

Safety:

• This tool uses undocumented internal APIs (as documented by notebooklm-mcp-cli)
• Use for personal/experimental purposes only
• Cookie extraction is handled securely by the nlm login command

Troubleshooting

Installation Issues:

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

Authentication Failures:

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

Command Not Found:

# Verify installation
which nlm
# If not found, run install.sh again

Token Expiration:

# Refresh auth
nlm login

Advanced Usage

Profile Management:

# List all profiles with emails
nlm login profile list

# Switch profiles
nlm login switch work

# Delete a profile
nlm login profile delete work

Using uvx (No Install Required):

# Run nlm without installing
uvx --from notebooklm-mcp-cli nlm notebook list
