| description | Complete API for Google NotebookLM - full programmatic access including features not in the web UI. Create notebooks, add sources, generate all artifact types, download in multiple formats. Activates on explicit /notebooklm or intent like "create a podcast about X" |
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.
Prerequisites
IMPORTANT: Before using any command, you MUST authenticate:
notebooklm login
notebooklm list
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_PROFILE | Active profile name (default: default) |
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 named profiles (notebooklm profile create work, then notebooklm -p work login). Alternatively, use different NOTEBOOKLM_HOME directories per account.
Parallel agents: The CLI stores notebook context per profile (~/.notebooklm/profiles/<profile>/context.json, with a legacy fallback to ~/.notebooklm/context.json for the implicit default profile). Multiple concurrent agents that share a profile and use notebooklm use can overwrite each other's context — use one of the isolation strategies below.
Solutions for parallel workflows:
- Always use explicit notebook ID (recommended): Pass
-n <notebook_id> / --notebook <notebook_id> on notebook-scoped commands instead of relying on use
- Per-agent isolation via profiles:
export NOTEBOOKLM_PROFILE=agent-$ID (each profile gets its own context file)
- Per-agent isolation via home: Set unique
NOTEBOOKLM_HOME per agent: export NOTEBOOKLM_HOME=/tmp/agent-$ID
- Use full UUIDs: Avoid partial IDs in automation (they can become ambiguous)
Agent Setup Verification
Before starting workflows, verify auth is in place. Use --test --json (not bare --json) — bare --json only proves the cookie file parses; --test makes a network call and proves the cookies still authenticate against Google.
notebooklm auth check --test --json → require BOTH "status": "ok" AND "checks.token_fetch": true. Bare "status": "ok" (without --test) is a false-positive trap — a stale cookie file passes the parse check.notebooklm list --json → expect valid JSON (may be empty for new accounts).- If auth fails or is missing → run
notebooklm login first. This is the primary auth path: opens a browser, the user signs in to Google once, and the resulting storage_state.json is reused on every subsequent run. Works on any environment with a display.
- For headless contexts where opening a browser is not feasible, use
notebooklm login --browser-cookies <browser> instead — extracts the user's already-logged-in cookies from Chrome/Firefox/etc. (requires the [cookies] extra; rookiepy may not install on Python 3.13+). Use chrome::<profile-name-or-directory> to target one Chromium user-profile, or firefox::<container-name> / firefox::none to target one Firefox container.
- To survey signed-in Google accounts before picking one:
notebooklm auth inspect --browser <browser> (read-only; pass -v to see which Chromium user-profile each account came from, or --json for tooling). Scoped forms such as notebooklm auth inspect --browser 'chrome::Profile 1' inspect only that browser profile.
- Re-run step 1 after login to confirm.
- If auth was working but cookies went stale (Google rotated SIDTS, or you signed in fresh in the browser) → refresh the active profile in place instead of full re-login:
notebooklm auth refresh — server-side SIDTS refresh against the existing storage_state.json. Cheap and silent; safe to run on a schedule (cron / launchd / systemd) at 15–20 min cadence to keep an unattended profile warm.notebooklm auth refresh --browser-cookies <browser> — re-extract cookies from a running browser and match them back to the profile's recorded email in context.json. Use when the on-disk storage_state.json is too stale for the server-side refresh path but you've just signed back into Google in the browser. For Chromium-family browsers with multiple user-profiles (Chrome's Default, Profile 1, …), refresh fans out across all profiles to find the email — same path as auth inspect (issue #571). Use chrome::<profile-name-or-directory> when you already know the exact browser profile.- Both forms preserve the same
--profile (no new profile is created).
Note: notebooklm status reports context state (selected notebook); do not use it to verify auth.
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 contextnotebooklm auth check - diagnose auth issuesnotebooklm auth inspect - list Google accounts visible to a browser (read-only)notebooklm auth refresh - server-side SIDTS refresh of the active profile (no new profile, no destructive writes)notebooklm auth refresh --browser-cookies <browser> - re-extract cookies from a browser into the active profile (rebuilds storage_state.json for the same --profile, not a new one)notebooklm list - list notebooksnotebooklm source list - list sourcesnotebooklm artifact list - list artifactsnotebooklm language list - list supported languagesnotebooklm language get - get current languagenotebooklm 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 statusnotebooklm 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 notebooknotebooklm ask "..." - chat queries (without --save-as-note)notebooklm suggest-prompts - AI-suggested prompts for a notebook (read-only, no state change)notebooklm history - display conversation history (read-only)notebooklm source add - add sourcesnotebooklm profile list - list profilesnotebooklm profile create - create profilenotebooklm profile switch - switch active profilenotebooklm doctor - check environment health
Ask before running:
notebooklm delete, source delete, source delete-by-title, source clean, note delete, artifact delete, label delete, share remove, auth logout, clear, profile delete, or ask --new - destructive or state-changing. Once approved, pass --yes/-y where the command supports it. Most destructive --json commands still require explicit --yes and otherwise return a structured confirmation error (CONFIRM_REQUIRED or VALIDATION_ERROR, depending on the command family); current exceptions include share remove --json and ask --new --json, which skip the prompt for non-interactive callers.notebooklm generate * - long-running, may failnotebooklm download * - writes to filesystemnotebooklm 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)notebooklm research cancel <run_id> - state-changing; cancels a running research job (an in-progress job transitions to FAILED). Fire-and-forget: it does not confirm success — re-check with notebooklm research status.notebooklm ask "..." --save-as-note - writes a notenotebooklm history --save - writes a note

Parallel safety: Use explicit notebook IDs in parallel workflows. Notebook-scoped commands broadly support -n/--notebook (ask/history, source, artifact, generate, download, note, label, share, research, and notebook delete/rename/summary/metadata). Download commands also support -a/--artifact. For chat, use -c <conversation_id> to target a specific conversation.
Partial IDs: Use first 6+ characters of UUIDs. Must be unique prefix (fails if ambiguous). Works for ID-based commands such as use, source delete, and wait. For exact source-title deletion, use source delete-by-title "Title". 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
{"notebook": {"id": "abc123de-...", "title": "Research", "created_at": null}}
Add source:
$ notebooklm source add "https://example.com" --json
{"source": {"id": "def456...", "title": "Example", "type": "web_page", "url": "https://example.com"}}
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": "...", "kind": "web_page", "content": "Full indexed text...", "url": null, "char_count": 12345}
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:
fulltext = await client.sources.get_fulltext(notebook_id, ref.source_id)
matches = fulltext.find_citation_context(ref.cited_text)
if matches:
context, pos = matches[0]
Extract IDs: Singular endpoints wrap their result in an envelope —
parse .notebook.id (from create), .source.id (from source add),
or .task_id (from generate *). The chat --json references list uses
.references[].source_id.
Generation Types
Common generate options vary by subcommand:
-n, --notebook targets the notebook.-s, --source limits generation to specific source(s) on content generators (not revise-slide).--language sets output language where supported (defaults to configured language or en).--wait, --timeout, and --interval are shared polling controls where waiting is supported.--json returns machine-readable output.--retry N automatically retries rate limits on supported subcommands (not mind-map).--prompt-file PATH reads description/query text from a file on ask, generation subcommands except mind-map, and source add-research.
| Type | Command | Options | Download |
|---|
| Podcast | generate audio | --format [deep-dive|brief|critique|debate], --length [short|default|long] | .mp3 |
| Video | generate video | --format [explainer|brief|cinematic] (⁴), --style [auto|custom|classic|whiteboard|kawaii|anime|watercolor|retro-print|heritage|paper-craft], --style-prompt with --style custom | .mp4 |
| Slide Deck | generate slide-deck | --format [detailed|presenter], --length [default|short] (²) | .pdf / .pptx |
| Slide Revision | generate revise-slide "prompt" --artifact <id> --slide N | --wait, --notebook | (re-downloads parent deck) |
| Infographic | generate infographic | --orientation [landscape|portrait|square], --detail [concise|standard|detailed], --style [auto|sketch-note|professional|bento-grid|editorial|instructional|bricks|clay|anime|kawaii|scientific] | .png |
| Report | generate report | --format [briefing-doc|study-guide|blog-post|custom], --append "extra instructions" (¹) | .md |
| Mind Map | generate mind-map | --kind [interactive|note-backed] (³) (default: interactive) | .json |
| Data Table | generate data-table | description required | .csv |
| Quiz | generate quiz | --difficulty [easy|medium|hard], --quantity [fewer|standard|more] | .json/.md/.html |
| Flashcards | generate flashcards | --difficulty [easy|medium|hard], --quantity [fewer|standard|more] | .json/.md/.html |
¹ --append only customizes the built-in templates. With --format custom, pass the prompt as the positional DESCRIPTION argument (notebooklm generate report "PROMPT" --format custom); --append is silently ignored in that mode (the CLI prints a warning).
³ Two kinds of mind map (issue #1256). generate mind-map --kind interactive (the default) creates the interactive studio artifact (what the web app now makes); it is polled to completion. generate mind-map --kind note-backed creates the note-backed kind — a JSON node tree, generated synchronously. Both emit the same {mind_map, note_id, kind} JSON, list under artifact list --type mind-map, and export via download mind-map. --instructions applies only to the note-backed kind.
⁴ Cinematic video (Veo 3). generate video --format cinematic generates AI documentary footage via Veo 3; it ignores --style, takes ~30-40 min, and requires a Google AI Ultra subscription. Also exposed as the generate cinematic-video alias (which forces --format cinematic and a longer default timeout). Download with download video or the download cinematic-video alias.
² Portrait / vertical slide decks via prompt. Slide-deck has no --orientation flag (unlike infographic). Treat portrait decks as skill-level prompt guidance, not a typed CLI/API contract: NotebookLM currently honors orientation cues written into the DESCRIPTION positional argument. Including phrases like "9:16 portrait", "vertical layout", "portrait mobile format", or "vertical 9:16 layout" can make NotebookLM render each slide as a 9:16 portrait image. Empirically:
- The
.pptx canvas itself may stay 16:9, but each slide's embedded image can be rendered as 9:16 portrait — useful for vertical/mobile video material extracted via python-pptx.
- Orientation is steered once at generation time.
generate revise-slide edits content within an existing slide but does not change its orientation; if a slide falls back to landscape (occasional inconsistency), regenerate the whole deck rather than revising the single page.
- Combine with an explicit page count in the prompt (e.g.
"Create exactly 8 pages, using a vertical 9:16 portrait layout") for the most predictable output.
notebooklm generate slide-deck "Create an 8-page deck in 9:16 portrait orientation for mobile viewing" --length default
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 |
| Slide deck as PPTX | download slide-deck --format pptx | Download slide deck as editable .pptx (web UI only offers PDF) |
| Slide revision | generate revise-slide "prompt" --artifact <id> --slide N | Modify individual slides with a natural-language prompt |
| Report template append | generate report --format study-guide --append "..." | Append custom instructions to built-in format templates without losing the format type |
| Source fulltext | source fulltext <id> | Retrieve the indexed text content of any source |
| Save chat to note | ask "..." --save-as-note / history --save | Save Q&A answers or conversation history as notebook notes |
| Programmatic sharing | share commands | Manage sharing permissions without the UI |
Common Workflows
Research to Podcast (Interactive)
Time: 5-10 minutes total
notebooklm create "Research: [topic]" — if fails: check auth with notebooklm loginnotebooklm source add for each URL/document — if one fails: log warning, continue with others- Wait for sources:
notebooklm source list --json until all status=READY — required before generation
notebooklm generate audio "Focus on [specific angle]" (confirm when asked) — if rate limited: wait 5 min, retry once- Note the artifact ID returned
- Check
notebooklm artifact list later for status
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):
- Create notebook and add sources as usual
- Wait for sources to be ready (use
source wait or check source list --json)
- Run
notebooklm generate audio "..." --json → parse task_id from output
- Spawn a background agent using Task tool:
Task(
prompt="Wait for artifact {task_id} in notebook {notebook_id} to complete, then download.
Use: notebooklm artifact wait {task_id} -n {notebook_id} --timeout 1200
Then: notebooklm download audio ./podcast.mp3 -a {task_id} -n {notebook_id}",
subagent_type="general-purpose"
)
- 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
notebooklm create "Analysis: [project]"notebooklm source add ./doc.pdf (or URLs)notebooklm ask "Summarize the key points"notebooklm ask "What are the main arguments?"- Continue chatting as needed
Bulk Import
Time: Varies by source count
notebooklm create "Collection: [name]"- Add multiple sources:
notebooklm source add "https://url1.com"
notebooklm source add "https://url2.com"
notebooklm source add ./local-file.pdf
notebooklm source list to verify
Source limits: Varies by plan—Standard: 50, Plus: 100, Pro: 300, Ultra: 600 sources per notebook. See NotebookLM plans for details. The CLI does not enforce these limits; they are applied by your NotebookLM account.
Supported types: PDFs, YouTube URLs, web URLs, Google Docs, text files, Markdown, Word docs, EPUB, 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:
- Add sources with
--json to capture IDs (parse with jq -r .source.id):
notebooklm source add "https://url1.com" --json
notebooklm source add "https://url2.com" --json
- 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 600
Report when all ready or if any fail.",
subagent_type="general-purpose"
)
- Main conversation continues while agent waits
- Once sources are ready, proceed with chat or generation
Why wait for sources? Sources must be indexed before chat or generation. Takes ~30 seconds to several minutes per source (see the processing-times table below).
Deep Web Research (Subagent Pattern)
Time: 15-30+ minutes, runs in background
Deep research finds and analyzes web sources on a topic:
- Create notebook:
notebooklm create "Research: [topic]"
- Start deep research (non-blocking):
notebooklm source add-research "topic query" --mode deep --no-wait
- 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 1800
Report how many sources were imported.",
subagent_type="general-purpose"
)
- Main conversation continues while agent waits
- When agent completes, sources are imported automatically
Alternative (blocking): For simple cases, omit --no-wait:
notebooklm source add-research "topic" --mode deep --import-all
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, 15-30+ 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:
notebooklm list --json
notebooklm auth check --test --json
notebooklm source list --json
notebooklm artifact list --json
JSON schemas (key fields):
notebooklm list --json:
{"notebooks": [{"index": 1, "id": "...", "title": "...", "is_owner": true, "created_at": "..."}], "count": 1}
notebooklm auth check --test --json (use --test to drive the network token-fetch — bare --json would leave "token_fetch": null):
{"status": "ok", "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:
{"notebook_id": "...", "notebook_title": "...", "sources": [{"index": 1, "id": "...", "title": "...", "type": "web_page", "url": "...", "status": "ready|processing|error", "status_id": 1, "created_at": "..."}], "count": 1}
notebooklm artifact list --json:
{"notebook_id": "...", "notebook_title": "...", "artifacts": [{"index": 1, "id": "...", "title": "...", "type": "Audio", "type_id": 1, "status": "in_progress|pending|completed|unknown", "status_id": 1, "created_at": "..."}], "count": 1}
Status values:
- Sources:
processing → ready (or error)
- Artifacts:
pending or in_progress → completed (or unknown)
Error Handling
On failure, offer the user a choice:
- Retry the operation
- Skip and continue with something else
- 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 failedartifact wait returns 2 if timeout reached before completiongenerate returns 1 if rate limited (check stderr for details)
Long Prompts
When a prompt or query exceeds shell command-line length limits, use --prompt-file to read it from a file:
notebooklm ask --prompt-file ./long_question.txt
notebooklm generate report --prompt-file ./custom_report_prompt.txt
notebooklm source add-research --prompt-file ./research_query.txt --mode deep
--prompt-file is mutually exclusive with the positional text argument. The file is read as UTF-8 with trailing whitespace stripped. Supported on: ask, all generate subcommands (except mind-map), and source add-research.
Note: --prompt-file reads a prompt/query text file, not a source document. To upload a file as a notebook source, use source add ./file.pdf.
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:
- Check status:
notebooklm artifact list
- Retry after 5-10 minutes
- Use the NotebookLM web UI as fallback
Processing times vary significantly. Use the subagent pattern for long operations:
| Operation | Typical time | Suggested timeout |
|---|
