IMPORTANT: Before using any command, you MUST authenticate:
notebooklm login # Opens browser for Google OAuth
notebooklm list # Verify authentication works
If commands fail with authentication errors, re-run notebooklm login.
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:
-n <notebook_id> (for wait/download commands) or --notebook <notebook_id> (for others) instead of relying on useexport NOTEBOOKLM_PROFILE=agent-$ID (each profile gets its own context file)NOTEBOOKLM_HOME per agent: export NOTEBOOKLM_HOME=/tmp/agent-$IDBefore 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).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.
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.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.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.--profile (no new profile is created).Note:
notebooklm statusreports context state (selected notebook); do not use it to verify auth.
Explicit: User says "/notebooklm", "use notebooklm", or mentions the tool by name

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 -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.
Commands with --json return structured data for parsing:
Create notebook:
$ notebooklm create "Research" --json
{"notebook": {"id": "abc123de-...", "title": "Research", "created_at": null}}
# parse with: jq -r .notebook.id
Add source:
$ notebooklm source add "https://example.com" --json
{"source": {"id": "def456...", "title": "Example", "type": "SourceType.WEB_PAGE", "url": "https://example.com"}}
# parse with: jq -r .source.id
# Note: no `status` field on add — use `source list --json` or `source wait` to check processing state.
Generate artifact:
$ notebooklm generate audio "Focus on key points" --json
{"task_id": "xyz789...", "status": "pending"}
# When run with --wait, completed status also includes a `url` field.
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": "...", "content": "Full indexed text...", "_type_code": null, "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) # Returns list[(context, position)]
if matches:
context, pos = matches[0] # First match; check len(matches) > 1 for duplicates
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.
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 (supported on all subcommands except mind-map)--prompt-file PATH to read description/query from a file (supported on ask, generate subcommands except mind-map, and source add-research; mutually exclusive with positional argument; use for long prompts)| Type | Command | Options | Download |

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).
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:
.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.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."Create exactly 8 pages, using a vertical 9:16 portrait layout") for the most predictable output.# Skill prompt hint: ask NotebookLM to render each slide as a 9:16 portrait image
notebooklm generate slide-deck "Create an 8-page deck in 9:16 portrait orientation for mobile viewing" --length default
These capabilities are available via CLI but not in NotebookLM's web interface:

Then: notebooklm download audio ./podcast.mp3 -a {task_id} -n {notebook_id}",
subagent_type="general-purpose"
)
Error handling in subagent:
artifact wait returns exit code 2 (timeout): Report timeout, suggest checking artifact listBenefits: Non-blocking, user can do other work, automatic download on completion
Time: 1-2 minutes

notebooklm create "Collection: [name]"notebooklm source add "https://url1.com"
notebooklm source add "https://url2.com"
notebooklm source add ./local-file.pdf
notebooklm source list to verifySource 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
Time: Varies by source count
When adding multiple sources and needing to wait for processing before chat/generation:
--json to capture IDs (parse with jq -r .source.id):
notebooklm source add "https://url1.com" --json # → {"source": {"id": "abc...", ...}}
notebooklm source add "https://url2.com" --json # → {"source": {"id": "def...", ...}}
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"
)
Why wait for sources? Sources must be indexed before chat or generation. Takes 10-60 seconds per source.
Time: 2-5 minutes, runs in background
Deep research finds and analyzes web sources on a topic:
notebooklm create "Research: [topic]"notebooklm source add-research "topic query" --mode deep --no-wait
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"
)
Alternative (blocking): For simple cases, omit --no-wait:
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 DriveProgress updates: Brief status for each step
Fire-and-forget for long operations:
artifact waitJSON output: Use --json flag for machine-readable output:
notebooklm list --json
notebooklm auth check --test --json # use --test for network-validated auth (see § Agent Setup Verification)
notebooklm source 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"]}}

Status values:
processing → ready (or error)pending or in_progress → completed (or unknown)On failure, offer the user a choice:
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 |
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)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-filereads a prompt/query text file, not a source document. To upload a file as a notebook source, usesource add ./file.pdf.
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:
Unreliable operations: These may fail with rate limiting:
Workaround: If generation fails:
notebooklm artifact listProcessing 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.
