# NotebookLM Automation

Complete programmatic access to Google NotebookLM—including capabilities not exposed in the web UI. Create notebooks, add sources (URLs, YouTube, PDFs, audio, video, images), chat with content, generate all artifact types, and download results in multiple formats.

## Installation

**From PyPI (Recommended):**
```bash
pip install notebooklm-py
```

**From GitHub (use latest release tag, NOT main branch):**
```bash
# Get the latest release tag (using curl)
LATEST_TAG=$(curl -s https://api.github.com/repos/teng-lin/notebooklm-py/releases/latest | grep '"tag_name"' | cut -d'"' -f4)
pip install "git+https://github.com/teng-lin/notebooklm-py@${LATEST_TAG}"
```

⚠️ **DO NOT install from main branch** (`pip install git+https://github.com/teng-lin/notebooklm-py`). The main branch may contain unreleased/unstable changes. Always use PyPI or a specific release tag, unless you are testing unreleased features.

After installation, install the Claude Code skill:
```bash
notebooklm skill install
```

## Prerequisites

**IMPORTANT:** Before using any command, you MUST authenticate:

```bash
notebooklm login          # Opens browser for Google OAuth
notebooklm list           # Verify authentication works
```

If commands fail with authentication errors, re-run `notebooklm login`.

### CI/CD, Multiple Accounts, and Parallel Agents

For automated environments, multiple accounts, or parallel agent workflows:

| Variable | Purpose |
|----------|---------|
| `NOTEBOOKLM_HOME` | Custom config directory (default: `~/.notebooklm`) |
| `NOTEBOOKLM_AUTH_JSON` | Inline auth JSON - no file writes needed |

**CI/CD setup:** Set `NOTEBOOKLM_AUTH_JSON` from a secret containing your `storage_state.json` contents.

**Multiple accounts:** Use different `NOTEBOOKLM_HOME` directories per account.

**Parallel agents:** The CLI stores notebook context in a shared file (`~/.notebooklm/context.json`). Multiple concurrent agents using `notebooklm use` can overwrite each other's context.

**Solutions for parallel workflows:**
1. **Always use explicit notebook ID** (recommended): Pass `-n <notebook_id>` (for `wait`/`download` commands) or `--notebook <notebook_id>` (for others) instead of relying on `use`
2. **Per-agent isolation:** Set unique `NOTEBOOKLM_HOME` per agent: `export NOTEBOOKLM_HOME=/tmp/agent-$ID`
3. **Use full UUIDs:** Avoid partial IDs in automation (they can become ambiguous)

## Agent Setup Verification

Before starting workflows, verify the CLI is ready:

1. `notebooklm status` → Should show "Authenticated as: email@..."
2. `notebooklm list --json` → Should return valid JSON (even if empty notebooks list)
3. If either fails → Run `notebooklm login`

## When This Skill Activates

**Explicit:** User says "/notebooklm", "use notebooklm", or mentions the tool by name

**Intent detection:** Recognize requests like:
- "Create a podcast about [topic]"
- "Summarize these URLs/documents"
- "Generate a quiz from my research"
- "Turn this into an audio overview"
- "Create flashcards for studying"
- "Generate a video explainer"
- "Make an infographic"
- "Create a mind map of the concepts"
- "Download the quiz as markdown"
- "Add these sources to NotebookLM"

## Autonomy Rules

**Run automatically (no confirmation):**
- `notebooklm status` - check context
- `notebooklm auth check` - diagnose auth issues
- `notebooklm list` - list notebooks
- `notebooklm source list` - list sources
- `notebooklm artifact list` - list artifacts
- `notebooklm language list` - list supported languages
- `notebooklm language get` - get current language
- `notebooklm language set` - set language (global setting)
- `notebooklm artifact wait` - wait for artifact completion (in subagent context)
- `notebooklm source wait` - wait for source processing (in subagent context)
- `notebooklm research status` - check research status
- `notebooklm research wait` - wait for research (in subagent context)
- `notebooklm use <id>` - set context (⚠️ SINGLE-AGENT ONLY - use `-n` flag in parallel workflows)
- `notebooklm create` - create notebook
- `notebooklm ask "..."` - chat queries
- `notebooklm source add` - add sources

**Ask before running:**
- `notebooklm delete` - destructive
- `notebooklm generate *` - long-running, may fail
- `notebooklm download *` - writes to filesystem
- `notebooklm artifact wait` - long-running (when in main conversation)
- `notebooklm source wait` - long-running (when in main conversation)
- `notebooklm research wait` - long-running (when in main conversation)

**Parallel safety:** Use explicit notebook IDs in parallel workflows. Commands supporting `-n` shorthand: `artifact wait`, `source wait`, `research wait/status`, `download *`. Download commands also support `-a/--artifact`. Other commands use `--notebook`. For chat, use `--new` to start fresh conversations (avoids conversation ID conflicts).

**Partial IDs:** Use first 6+ characters of UUIDs. Must be unique prefix (fails if ambiguous). Works for: `use`, `delete`, `wait` commands. For automation, prefer full UUIDs to avoid ambiguity.

## Command Output Formats

Commands with `--json` return structured data for parsing:

**Create notebook:**
```
$ notebooklm create "Research" --json
{"id": "abc123de-...", "title": "Research"}
```

**Add source:**
```
$ notebooklm source add "https://example.com" --json
{"source_id": "def456...", "title": "Example", "status": "processing"}
```

**Generate artifact:**
```
$ notebooklm generate audio "Focus on key points" --json
{"task_id": "xyz789...", "status": "pending"}
```

**Chat with references:**
```
$ notebooklm ask "What is X?" --json
{"answer": "X is... [1] [2]", "conversation_id": "...", "turn_number": 1, "is_follow_up": false, "references": [{"source_id": "abc123...", "citation_number": 1, "cited_text": "Relevant passage from source..."}, {"source_id": "def456...", "citation_number": 2, "cited_text": "Another passage..."}]}
```

**Source fulltext (get indexed content):**
```
$ notebooklm source fulltext <source_id> --json
{"source_id": "...", "title": "...", "char_count": 12345, "content": "Full indexed text..."}
```

**Understanding citations:** The `cited_text` in references is often a snippet or section header, not the full quoted passage. The `start_char`/`end_char` positions reference NotebookLM's internal chunked index, not the raw fulltext. Use `SourceFulltext.find_citation_context()` to locate citations:
```python
fulltext = await client.sources.get_fulltext(notebook_id, ref.source_id)
matches = fulltext.find_citation_context(ref.cited_text)  # Returns list[(context, position)]
if matches:
    context, pos = matches[0]  # First match; check len(matches) > 1 for duplicates
```

**Extract IDs:** Parse the `id`, `source_id`, or `task_id` field from JSON output.

## Generation Types

All generate commands support:
- `-s, --source` to use specific source(s) instead of all sources
- `--language` to set output language (defaults to configured language or 'en')
- `--json` for machine-readable output (returns `task_id` and `status`)
- `--retry N` to automatically retry on rate limits with exponential backoff

## Features Beyond the Web UI

These capabilities are available via CLI but not in NotebookLM's web interface:

| Feature | Command | Description |
|---------|---------|-------------|
| **Batch downloads** | `download <type> --all` | Download all artifacts of a type at once |
| **Quiz/Flashcard export** | `download quiz --format json` | Export as JSON, Markdown, or HTML (web UI only shows interactive view) |
| **Mind map extraction** | `download mind-map` | Export hierarchical JSON for visualization tools |
| **Data table export** | `download data-table` | Download structured tables as CSV |
| **Source fulltext** | `source fulltext <id>` | Retrieve the indexed text content of any source |
| **Programmatic sharing** | `share` commands | Manage sharing permissions without the UI |

## Common Workflows

### Research to Podcast (Interactive)
**Time:** 5-10 minutes total

1. `notebooklm create "Research: [topic]"` — *if fails: check auth with `notebooklm login`*
2. `notebooklm source add` for each URL/document — *if one fails: log warning, continue with others*
3. Wait for sources: `notebooklm source list --json` until all status=READY — *required before generation*
4. `notebooklm generate audio "Focus on [specific angle]"` (confirm when asked) — *if rate limited: wait 5 min, retry once*
5. Note the artifact ID returned
6. Check `notebooklm artifact list` later for status
7. `notebooklm download audio ./podcast.mp3` when complete (confirm when asked)

### Research to Podcast (Automated with Subagent)
**Time:** 5-10 minutes, but continues in background

When user wants full automation (generate and download when ready):

1. Create notebook and add sources as usual
2. Wait for sources to be ready (use `source wait` or check `source list --json`)
3. Run `notebooklm generate audio "..." --json` → parse `artifact_id` from output
4. **Spawn a background agent** using Task tool:
   ```
   Task(
     prompt="Wait for artifact {artifact_id} in notebook {notebook_id} to complete, then download.
             Use: notebooklm artifact wait {artifact_id} -n {notebook_id} --timeout 600
             Then: notebooklm download audio ./podcast.mp3 -a {artifact_id} -n {notebook_id}",
     subagent_type="general-purpose"
   )
   ```
5. Main conversation continues while agent waits

**Error handling in subagent:**
- If `artifact wait` returns exit code 2 (timeout): Report timeout, suggest checking `artifact list`
- If download fails: Check if artifact status is COMPLETED first

**Benefits:** Non-blocking, user can do other work, automatic download on completion

### Document Analysis
**Time:** 1-2 minutes

1. `notebooklm create "Analysis: [project]"`
2. `notebooklm source add ./doc.pdf` (or URLs)
3. `notebooklm ask "Summarize the key points"`
4. `notebooklm ask "What are the main arguments?"`
5. Continue chatting as needed

### Bulk Import
**Time:** Varies by source count

1. `notebooklm create "Collection: [name]"`
2. Add multiple sources:
   ```bash
   notebooklm source add "https://url1.com"
   notebooklm source add "https://url2.com"
   notebooklm source add ./local-file.pdf
   ```
3. `notebooklm source list` to verify

**Source limits:** Max 50 sources per notebook
**Supported types:** PDFs, YouTube URLs, web URLs, Google Docs, text files, Markdown, Word docs, audio files, video files, images

### Bulk Import with Source Waiting (Subagent Pattern)
**Time:** Varies by source count

When adding multiple sources and needing to wait for processing before chat/generation:

1. Add sources with `--json` to capture IDs:
   ```bash
   notebooklm source add "https://url1.com" --json  # → {"source_id": "abc..."}
   notebooklm source add "https://url2.com" --json  # → {"source_id": "def..."}
   ```
2. **Spawn a background agent** to wait for all sources:
   ```
   Task(
     prompt="Wait for sources {source_ids} in notebook {notebook_id} to be ready.
             For each: notebooklm source wait {id} -n {notebook_id} --timeout 120
             Report when all ready or if any fail.",
     subagent_type="general-purpose"
   )
   ```
3. Main conversation continues while agent waits
4. Once sources are ready, proceed with chat or generation

**Why wait for sources?** Sources must be indexed before chat or generation. Takes 10-60 seconds per source.

### Deep Web Research (Subagent Pattern)
**Time:** 2-5 minutes, runs in background

Deep research finds and analyzes web sources on a topic:

1. Create notebook: `notebooklm create "Research: [topic]"`
2. Start deep research (non-blocking):
   ```bash
   notebooklm source add-research "topic query" --mode deep --no-wait
   ```
3. **Spawn a background agent** to wait and import:
   ```
   Task(
     prompt="Wait for research in notebook {notebook_id} to complete and import sources.
             Use: notebooklm research wait -n {notebook_id} --import-all --timeout 300
             Report how many sources were imported.",
     subagent_type="general-purpose"
   )
   ```
4. Main conversation continues while agent waits
5. When agent completes, sources are imported automatically

**Alternative (blocking):** For simple cases, omit `--no-wait`:
```bash
notebooklm source add-research "topic" --mode deep --import-all
# Blocks for up to 5 minutes
```

**When to use each mode:**
- `--mode fast`: Specific topic, quick overview needed (5-10 sources, seconds)
- `--mode deep`: Broad topic, comprehensive analysis needed (20+ sources, 2-5 min)

**Research sources:**
- `--from web`: Search the web (default)
- `--from drive`: Search Google Drive

## Output Style

**Progress updates:** Brief status for each step
- "Creating notebook 'Research: AI'..."
- "Adding source: https://example.com..."
- "Starting audio generation... (task ID: abc123)"

**Fire-and-forget for long operations:**
- Start generation, return artifact ID immediately
- Do NOT poll or wait in main conversation - generation takes 5-45 minutes (see timing table)
- User checks status manually, OR use subagent with `artifact wait`

**JSON output:** Use `--json` flag for machine-readable output:
```bash
notebooklm list --json
notebooklm auth check --json
notebooklm source list --json
notebooklm artifact list --json
```

**JSON schemas (key fields):**

`notebooklm list --json`:
```json
{"notebooks": [{"id": "...", "title": "...", "created_at": "..."}]}
```

`notebooklm auth check --json`:
```json
{"checks": {"storage_exists": true, "json_valid": true, "cookies_present": true, "sid_cookie": true, "token_fetch": true}, "details": {"storage_path": "...", "auth_source": "file", "cookies_found": ["SID", "HSID", "..."], "cookie_domains": [".google.com"]}}
```

`notebooklm source list --json`:
```json
{"sources": [{"id": "...", "title": "...", "status": "ready|processing|error"}]}
```

`notebooklm artifact list --json`:
```json
{"artifacts": [{"id": "...", "title": "...", "type": "Audio Overview", "status": "in_progress|pending|completed|unknown"}]}
```

**Status values:**
- Sources: `processing` → `ready` (or `error`)
- Artifacts: `pending` or `in_progress` → `completed` (or `unknown`)

## Error Handling

**On failure, offer the user a choice:**
1. Retry the operation
2. Skip and continue with something else
3. Investigate the error

**Error decision tree:**

| Error | Cause | Action |
|-------|-------|--------|
| Auth/cookie error | Session expired | Run `notebooklm auth check` then `notebooklm login` |
| "No notebook context" | Context not set | Use `-n <id>` or `--notebook <id>` flag (parallel), or `notebooklm use <id>` (single-agent) |
| "No result found for RPC ID" | Rate limiting | Wait 5-10 min, retry |
| `GENERATION_FAILED` | Google rate limit | Wait and retry later |
| Download fails | Generation incomplete | Check `artifact list` for status |
| Invalid notebook/source ID | Wrong ID | Run `notebooklm list` to verify |
| RPC protocol error | Google changed APIs | May need CLI update |

## Exit Codes

All commands use consistent exit codes:

| Code | Meaning | Action |
|------|---------|--------|
| 0 | Success | Continue |
| 1 | Error (not found, processing failed) | Check stderr, see Error Handling |
| 2 | Timeout (wait commands only) | Extend timeout or check status manually |

**Examples:**
- `source wait` returns 1 if source not found or processing failed
- `artifact wait` returns 2 if timeout reached before completion
- `generate` returns 1 if rate limited (check stderr for details)

## Known Limitations

**Rate limiting:** Audio, video, quiz, flashcards, infographic, and slide deck generation may fail due to Google's rate limits. This is an API limitation, not a bug.

**Reliable operations:** These always work:
- Notebooks (list, create, delete, rename)
- Sources (add, list, delete)
- Chat/queries
- Mind-map, study-guide, report, data-table generation

**Unreliable operations:** These may fail with rate limiting:
- Audio (podcast) generation
- Video generation
- Quiz and flashcard generation
- Infographic and slide deck generation

**Workaround:** If generation fails:
1. Check status: `notebooklm artifact list`
2. Retry after 5-10 minutes
3. Use the NotebookLM web UI as fallback

**Processing times vary significantly.** Use the subagent pattern for long operations:

| Operation | Typical time | Suggested timeout |
|-----------|--------------|-------------------|
| Source processing | 30s - 10 min | 600s |
| Research (fast) | 30s - 2 min | 180s |
| Research (deep) | 15 - 30+ min | 1800s |
| Notes | instant | n/a |
| Mind-map | instant (sync) | n/a |
| Quiz, flashcards | 5 - 15 min | 900s |
| Report, data-table | 5 - 15 min | 900s |
| Audio generation | 10 - 20 min | 1200s |
| Video generation | 15 - 45 min | 2700s |

**Polling intervals:** When checking status manually, poll every 15-30 seconds to avoid excessive API calls.

## Language Configuration

Language setting controls the output language for generated artifacts (audio, video, etc.).

**Important:** Language is a **GLOBAL** setting that affects all notebooks in your account.

```bash
# List all 80+ supported languages with native names
notebooklm language list

# Show current language setting
notebooklm language get

# Set language for artifact generation
notebooklm language set zh_Hans  # Simplified Chinese
notebooklm language set ja       # Japanese
notebooklm language set en       # English (default)
```

**Common language codes:**
| Code | Language |
|------|----------|
| `en` | English |
| `zh_Hans` | 中文（简体） - Simplified Chinese |
| `zh_Hant` | 中文（繁體） - Traditional Chinese |
| `ja` | 日本語 - Japanese |
| `ko` | 한국어 - Korean |
| `es` | Español - Spanish |
| `fr` | Français - French |
| `de` | Deutsch - German |
| `pt_BR` | Português (Brasil) |

**Override per command:** Use `--language` flag on generate commands:
```bash
notebooklm generate audio --language ja   # Japanese podcast
notebooklm generate video --language zh_Hans  # Chinese video
```

**Offline mode:** Use `--local` flag to skip server sync:
```bash
notebooklm language set zh_Hans --local  # Save locally only
notebooklm language get --local  # Read local config only
```

## Troubleshooting

```bash
notebooklm --help              # Main commands
notebooklm auth check          # Diagnose auth issues
notebooklm auth check --test   # Full auth validation with network test
notebooklm notebook --help     # Notebook management
notebooklm source --help       # Source management
notebooklm research --help     # Research status/wait
notebooklm generate --help     # Content generation
notebooklm artifact --help     # Artifact management
notebooklm download --help     # Download content
notebooklm language --help     # Language settings
```

**Diagnose auth:** `notebooklm auth check` - shows cookie domains, storage path, validation status
**Re-authenticate:** `notebooklm login`
**Check version:** `notebooklm --version`
**Update skill:** `notebooklm skill install`
