description: Install, authenticate, troubleshoot, and operate Gemini Notebook through the notebooklm-py CLI or typed async Python API. Use for notebook and source management, grounded chat and research, and artifact generation or download when the user mentions Gemini Notebook, notebooklm-py, the notebooklm CLI, or its Python API. Do not use for the generic Gemini API or unrelated content creation.
Gemini Notebook Automation
Use the notebooklm CLI for agent workflows. Prefer --json and explicit IDs so every
operation is inspectable and safe under concurrency. Use the typed async Python API only when the
user requests application code or the CLI cannot express the workflow. The readiness, identity,
authorization, and credential-handling rules below apply to both interfaces.
Setup and Authentication
Requires Python 3.10+. Install the package in the user's existing environment; do not create a
separate environment unless requested:
If system pip reports externally-managed-environment, do not use --break-system-packages.
For CLI-only use, offer uv tool install "notebooklm-py[browser]" or the equivalent pipx
command; for application code, use the user's active project environment.
For unattended or headless work, prefer durable profile-backed master-token auth over a copied
cookie snapshot. Install pip install "notebooklm-py[headless]"; the one-time automatic OAuth
capture also needs [browser]. On a trusted workstation run
notebooklm login --master-token --account <email>, then deploy master_token.json, not
storage_state.json, to the selected profile. NOTEBOOKLM_HOME selects the private base directory
and NOTEBOOKLM_PROFILE selects its profile; defaults resolve to
~/.notebooklm/profiles/default/master_token.json.
In CI, NOTEBOOKLM_MASTER_TOKEN_JSON is a secret-transport convention, not an environment variable
the package reads directly. Write its exact value to the selected profile's master_token.json
with mode 0600, unset it, then run notebooklm auth refresh to mint storage_state.json. A
sibling master token can automatically re-mint expired file-backed cookies. Inline
NOTEBOOKLM_AUTH_JSON is only a short-lived fallback; it bypasses this recovery path.
Use PyPI or a release tag, not an unreleased main checkout. When available, consult the
installation guide.
Before a workflow, verify real authentication rather than merely parsing the cookie file:
notebooklm auth check --test --json
Require .status == "ok" and .checks.token_fetch == true. If validation fails:
With a display, run notebooklm login and validate again.
In a headless environment, install [cookies] and use
notebooklm login --browser-cookies <browser>. Use
notebooklm auth inspect --browser <browser> first when account selection is unclear.
If previously valid cookies became stale, try notebooklm auth refresh; use
notebooklm auth refresh --browser-cookies <browser> after signing back into the browser.
The normal --test preflight may heal and persist refreshed cookies. Add --passive when the
check must be strictly read-only, including the failure-diagnosis workflow below.
notebooklm status reports selected-notebook context, not authentication.
Treat both auth files as bearer credentials: never print, log, or commit them. A master token is a
durable full-account credential that survives password changes; use a dedicated account, protect
it in a secret store and as 0600 on disk, and explicitly revoke it if exposed.
Operating Invariants
Use --json for discovery and mutations, then retain the returned full UUIDs. Important
envelopes are .notebook.id from create, .source.id from source add, and .task_id from
asynchronous generators. generate mind-map instead returns mind_map, note_id, and kind;
both kinds return a finished result with no task ID or separate artifact wait step.
Pass -n/--notebook <id> on every notebook-scoped command in automation or concurrent work.
Do not rely on notebooklm use. For every concurrent run, also set a unique
NOTEBOOKLM_PROFILE=agent-<id> so context and profile writes are isolated. A new profile has no
credentials: put a master_token.json copy in that profile and mint its storage before use.
Never share one writable storage_state.json across agents.
After adding sources, retain every .source.id, then run source wait for each before chat or
generation. The add envelope has no status. Require wait exit 0 and status == "ready"; let the
waiter handle media-specific transient error rows.
After an asynchronous generator returns a task/artifact ID, pass it positionally to
artifact wait with -n <notebook_id>. Download that exact artifact with
-a <artifact_id> -n <notebook_id>; never select the latest visible artifact. Mind-map generation
returns its completed result directly and does not need artifact wait.
For overlapping research runs, always pass --run-id <research_run_id>.
Use a host's background facility only when it actually exists. Keep wait and dependent download
commands in one sequential job, and download only after the wait exits 0. Otherwise run in the
foreground or return exact ID-pinned commands to the user.
Authorization Boundaries
Safe inspection and explicitly requested creation, source addition, chat, and prompt suggestion can
run directly. Diagnose failures with read-only commands before attempting recovery.
Obtain confirmation immediately before an action when it was not already clearly authorized:
destructive commands such as notebook/source/note/artifact/label/profile deletion, sharing
removal, logout, clear, research cancellation, and ask --new;
language set, because the default mode changes the account-global output language (prefer a
generation command's --language override);
generation or long foreground waits, which can take minutes and be rate-limited;
downloads, which write files;
research wait --import-all, which imports sources;
ask --save-as-note and history --save, which create notes.
User intent, not the presence of a CLI prompt, is the authorization boundary. After authorization,
pass --yes/-y where supported. Most destructive JSON commands refuse to prompt without it, but
some, including ask --new --json and share remove --json, execute without prompting. Never
treat prompt absence as consent.
research cancel is fire-and-forget. After an authorized cancellation, verify the exact run with
notebooklm research status -n <notebook_id> --run-id <research_run_id> --json.
Command Discovery
Use the installed CLI's help as the version-matched source of truth instead of guessing flags:
Also inspect notebooklm --version and drill down to the exact command, such as
notebooklm generate audio --help, whenever its help differs from this skill.
Common operations:
Goal
Command
Check compute usage
notebooklm usage --json; notebooklm usage --categories for category availability and estimated costs
List or create notebooks
notebooklm list --json; notebooklm create "Title" --json
notebooklm download <type> <path> -n <nb> -a <artifact>
For the full surface, consult the installed command help or, when available, the
CLI reference.
For application code, use the baseline below and, when available, the
Python API guide.
Canonical Source-to-Artifact Workflow
Keep {notebook_id}, every {source_id}, and {artifact_id} from JSON output:
An explicit request for this completed workflow authorizes its normal prerequisite waits, requested
generation, and requested output file. Confirm only work not already authorized by that request.
notebooklm create "Research: topic" --json
notebooklm source add <input> -n {notebook_id} --json for each input.
Once the foreground wait is authorized, run
notebooklm source wait {source_id} -n {notebook_id} --timeout 600 for every captured source.
Once generation is authorized, generate the requested type. For audio:
notebooklm generate audio "instructions" -n {notebook_id} -s {source_id} --json.
Repeat -s for each selected source and capture .task_id as {artifact_id}.
Once the foreground wait is authorized, run
notebooklm artifact wait {artifact_id} -n {notebook_id} --timeout 1200.
Once the output write is authorized, run
notebooklm download audio ./podcast.m4a -a {artifact_id} -n {notebook_id}.
For analysis without generation, replace steps 4-6 with an ID-pinned chat command only after every
source is ready:
notebooklm ask "Summarize the key arguments" -n {notebook_id} --json
Deep Research
Deep research can take 15-30+ minutes. Start it non-blocking and retain
.poll_task_id // .task_id as {research_run_id}:
notebooklm source add-research "query" -n {notebook_id} --mode deep --no-wait --json
Import only after explicit authorization, pinning both IDs:
With --import-all, --timeout is a per-phase budget for polling and import retry, so this example
can consume roughly 3600 seconds of host wall time.
Retain newly created source IDs from .imported_sources[].id and wait for readiness before later
chat or generation.
Python API Baseline
When the full API guide is unavailable, use the installed typed API and its docstrings; do not guess
method names. Keep the same IDs and readiness gates as the CLI workflow:
import asyncio
from notebooklm import NotebookLMClient
async def main(url: str) -> None:
async with NotebookLMClient.from_storage() as client:
notebook = await client.notebooks.create("Research: topic")
source = await client.sources.add_url(notebook.id, url)
await client.sources.wait_until_ready(notebook.id, source.id, timeout=600)
answer = await client.chat.ask(
notebook.id, "Summarize the key arguments", source_ids=[source.id]
)
print(answer.answer)
task = await client.artifacts.generate_audio(
notebook.id,
source_ids=[source.id],
instructions="Focus on the key arguments",
)
final = await client.artifacts.wait_for_completion(notebook.id, task.task_id, timeout=1200)
if not final.is_complete:
raise RuntimeError(f"Generation ended with {final.status}: {final.error}")
await client.artifacts.download_audio(
notebook.id, "./podcast.m4a", artifact_id=task.task_id
)
asyncio.run(main("https://example.com"))
NotebookLMClient.from_storage() is an async context manager and is not awaited. A client is
re-entrant on one event loop but is not thread-safe; create one client per loop. Public namespaces
include notebooks, sources, chat, research, artifacts, mind_maps, notes, settings,
sharing, labels, and collections. Apply the authorization boundaries above before running
state-changing, long-running, or file-writing calls.
Generation Notes
Available generators include audio, video, slide-deck, infographic, report, mind-map,
data-table, quiz, and flashcards. Inspect notebooklm generate <type> --help because formats,
styles, source selection, language, and retry support vary by type.
Keep these non-obvious distinctions:
Mind map (--kind interactive, default) is an asynchronous studio artifact internally, but the
CLI polls it to completion and returns {mind_map, note_id, kind}; do not run artifact wait.
Mind map (--kind note-backed) is server-synchronous. Both kinds accept --instructions;
interactive applies it reliably, while the server may ignore it for note-backed maps.
generate video --format cinematic ignores --style, requires Google AI Ultra, and can take
roughly 30-40 minutes.
Slide-deck has no orientation flag. Request portrait output in the description (for example,
9:16 portrait); slide revision cannot change the deck's orientation.
For a custom report, pass the prompt as the positional description with --format custom;
--append applies only to built-in report formats.
For prompts too long or awkward for shell quoting, use --prompt-file PATH on ask,
source add-research, and supported generators. It contains prompt text; upload source documents
with source add instead.
Output and Citations
Use JSON structurally rather than parsing human output. Common lifecycle values are:
sources: unknown/preparing/processing -> ready or error; proceed only on ready;
artifacts: pending/in_progress -> completed, failed, or removed; not_found may be a
brief listing lag. Proceed or download only on completed.
Chat JSON includes answer, conversation_id, and references[].source_id. A reference's
start_char/end_char are UTF-16 offsets into the structured source document, not flat
SourceFulltext.content. In Python, use
from notebooklm import resolve_chat_reference_passage, then call
await resolve_chat_reference_passage(client, notebook_id, reference); it uses the exact document
range and falls back to find_citation_context() when necessary.
Failure Handling
On failure, run safe read-only diagnosis first:
notebooklm auth check --test --passive --json
notebooklm list --json
notebooklm source list -n {notebook_id} --json
notebooklm artifact list -n {notebook_id} --json
notebooklm research status -n {notebook_id} --run-id {research_run_id} --json
Inspect only the commands relevant to the failed workflow. Do not mutate state during diagnosis.
Exit 0 means success. Expected command failures use exit 1. A source wait timeout uses exit 2;
artifact wait and research wait timeouts use exit 1.
Branch on exit code first. Ordinary handled JSON failures use {error, code, message}, while wait
commands return domain envelopes such as {"status": "timeout", "error": "..."}.
On auth failure, revalidate checks.token_fetch; log in only if it is not true.
On a wait timeout, report it and inspect the exact source, artifact, or research run.
Generation is rate-limited by Google. Preserve the task ID, inspect status, and retry only when the
user authorizes it; do not loop indefinitely. For an existing failed Studio artifact, inspect
notebooklm artifact retry <artifact_id> -n {notebook_id} --help before retrying in place.
On a protocol error, record the installed version, exact command, relevant IDs, and redacted
error. Check the project's issue tracker when network access exists; do not invent a workaround
when it does not.
Keep progress updates brief and include the relevant returned ID. Never expose credential contents.
