Status: Active Last Updated: 2026-01-20

Complete reference for the notebooklm Python library.

Quick Start

import asyncio
from notebooklm import NotebookLMClient

async def main():
    # Create client from saved authentication
    async with await NotebookLMClient.from_storage() as client:
        # List notebooks
        notebooks = await client.notebooks.list()
        print(f"Found {len(notebooks)} notebooks")

        # Create a new notebook
        nb = await client.notebooks.create("My Research")
        print(f"Created: {nb.id}")

        # Add sources
        await client.sources.add_url(nb.id, "https://example.com/article")

        # Ask a question
        result = await client.chat.ask(nb.id, "Summarize the main points")
        print(result.answer)

        # Generate a podcast
        status = await client.artifacts.generate_audio(nb.id)
        final = await client.artifacts.wait_for_completion(nb.id, status.task_id)
        print(f"Audio ready: {final.url}")

asyncio.run(main())

Core Concepts

Async Context Manager

The client must be used as an async context manager to properly manage HTTP connections:

# Correct - uses context manager
async with await NotebookLMClient.from_storage() as client:
    ...

# Also correct - manual management
client = await NotebookLMClient.from_storage()
await client.__aenter__()
try:
    ...
finally:
    await client.__aexit__(None, None, None)

Authentication

The client requires valid Google session cookies obtained via browser login:

# From storage file (recommended)
client = await NotebookLMClient.from_storage()
client = await NotebookLMClient.from_storage("/path/to/storage_state.json")

# From AuthTokens directly
from notebooklm import AuthTokens
auth = AuthTokens(
    cookies={"SID": "...", "HSID": "...", ...},
    csrf_token="...",
    session_id="..."
)
client = NotebookLMClient(auth)

Environment Variable Support:

The library respects these environment variables for authentication:

Precedence (highest to lowest):

1. Explicit path argument to from_storage()
2. NOTEBOOKLM_AUTH_JSON environment variable
3. $NOTEBOOKLM_HOME/storage_state.json
4. ~/.notebooklm/storage_state.json

CI/CD Example:

import os

# Set auth JSON from environment (e.g., GitHub Actions secret)
os.environ["NOTEBOOKLM_AUTH_JSON"] = '{"cookies": [...]}'

# Client automatically uses the env var
async with await NotebookLMClient.from_storage() as client:
    notebooks = await client.notebooks.list()

Error Handling

The library raises RPCError for API failures:

from notebooklm import RPCError

try:
    result = await client.notebooks.create("Test")
except RPCError as e:
    print(f"RPC failed: {e}")
    # Common causes:
    # - Session expired (re-run `notebooklm login`)
    # - Rate limited (wait and retry)
    # - Invalid parameters

Authentication & Token Refresh

Automatic Refresh: The client automatically refreshes CSRF tokens when authentication errors are detected. This happens transparently during any API call - you don't need to handle it manually.

When an RPC call fails with an auth error (HTTP 401/403 or auth-related message):

1. The client fetches fresh tokens from the NotebookLM homepage
2. Waits briefly to avoid rate limiting
3. Retries the failed request automatically

Manual Refresh: For proactive refresh (e.g., before a long-running operation):

async with await NotebookLMClient.from_storage() as client:
    # Manually refresh CSRF token and session ID
    await client.refresh_auth()

Note: If your session cookies have fully expired (not just CSRF tokens), you'll need to re-run notebooklm login.

API Reference

NotebookLMClient

Main client class providing access to all APIs.

class NotebookLMClient:
    notebooks: NotebooksAPI    # Notebook operations
    sources: SourcesAPI        # Source management
    artifacts: ArtifactsAPI    # AI-generated content
    chat: ChatAPI              # Conversations
    research: ResearchAPI      # Web/Drive research
    notes: NotesAPI            # User notes
    sharing: SharingAPI        # Notebook sharing

    @classmethod
    async def from_storage(cls, path: str = None) -> "NotebookLMClient"

    async def refresh_auth(self) -> AuthTokens

NotebooksAPI (client.notebooks)

Example:

# List all notebooks
notebooks = await client.notebooks.list()
for nb in notebooks:
    print(f"{nb.id}: {nb.title} ({nb.sources_count} sources)")

# Create and rename
nb = await client.notebooks.create("Draft")
nb = await client.notebooks.rename(nb.id, "Final Version")

# Get AI-generated description (parsed with suggested topics)
desc = await client.notebooks.get_description(nb.id)
print(desc.summary)
for topic in desc.suggested_topics:
    print(f"  - {topic.question}")

# Get raw summary text (unparsed)
summary = await client.notebooks.get_summary(nb.id)
print(summary)

# Share a notebook
await client.notebooks.share(nb.id, settings={"public": True})

get_summary vs get_description:

• get_summary() returns the raw summary text string
• get_description() returns a NotebookDescription object with the parsed summary and a list of SuggestedTopic objects for suggested questions

SourcesAPI (client.sources)

Example:

# Add various source types
await client.sources.add_url(nb_id, "https://example.com/article")
await client.sources.add_youtube(nb_id, "https://youtube.com/watch?v=...")
await client.sources.add_text(nb_id, "My Notes", "Content here...")
await client.sources.add_file(nb_id, Path("./document.pdf"))

# List and manage
sources = await client.sources.list(nb_id)
for src in sources:
    print(f"{src.id}: {src.title} ({src.kind})")

await client.sources.rename(nb_id, src.id, "Better Title")
await client.sources.refresh(nb_id, src.id)  # Re-fetch URL content

# Check if a source needs refreshing (content changed)
is_fresh = await client.sources.check_freshness(nb_id, src.id)
if not is_fresh:
    await client.sources.refresh(nb_id, src.id)

# Get full indexed content (what NotebookLM uses for answers)
fulltext = await client.sources.get_fulltext(nb_id, src.id)
print(f"Content ({fulltext.char_count} chars): {fulltext.content[:500]}...")

# Get AI-generated summary and keywords
guide = await client.sources.get_guide(nb_id, src.id)
print(f"Summary: {guide['summary']}")
print(f"Keywords: {guide['keywords']}")

ArtifactsAPI (client.artifacts)

Core Methods

Type-Specific List Methods

Generation Methods

Downloading Artifacts

Download Methods:

# Download the most recent completed audio overview
path = await client.artifacts.download_audio(nb_id, "podcast.mp4")

# Download a specific audio artifact by ID
path = await client.artifacts.download_audio(nb_id, "podcast.mp4", artifact_id="abc123")

# Download video overview
path = await client.artifacts.download_video(nb_id, "video.mp4")

# Download infographic
path = await client.artifacts.download_infographic(nb_id, "infographic.png")

# Download slide deck as PDF
path = await client.artifacts.download_slide_deck(nb_id, "./slides.pdf")
# Returns: "./slides.pdf"

# Download report as Markdown
path = await client.artifacts.download_report(nb_id, "./study-guide.md")
# Extracts markdown content from Briefing Doc, Study Guide, Blog Post, etc.

# Download mind map as JSON
path = await client.artifacts.download_mind_map(nb_id, "./concept-map.json")
# JSON structure: {"name": "Topic", "children": [{"name": "Subtopic", ...}]}

# Download data table as CSV
path = await client.artifacts.download_data_table(nb_id, "./data.csv")
# CSV uses UTF-8 with BOM encoding for Excel compatibility

# Download quiz as JSON (default)
path = await client.artifacts.download_quiz(nb_id, "quiz.json")

# Download quiz as markdown with answers marked
path = await client.artifacts.download_quiz(nb_id, "quiz.md", output_format="markdown")

# Download flashcards as JSON (normalizes f/b to front/back)
path = await client.artifacts.download_flashcards(nb_id, "cards.json")

# Download flashcards as markdown
path = await client.artifacts.download_flashcards(nb_id, "cards.md", output_format="markdown")

Notes:

• If artifact_id is not specified, downloads the first completed artifact of that type
• Raises ValueError if no completed artifact is found
• Some URLs require browser-based download (handled automatically)
• Report downloads extract the markdown content from the artifact
• Mind map downloads return a JSON tree structure with name and children fields
• Data table downloads parse the complex rich-text format into CSV rows/columns
• Quiz/flashcard formats: json (structured), markdown (readable), html (raw)

Export Methods

Export artifacts to Google Docs or Google Sheets.

Export Types (ExportType enum):

• ExportType.DOCS (1): Export to Google Docs
• ExportType.SHEETS (2): Export to Google Sheets

# Wait with polling
final = await client.artifacts.wait_for_completion(
    nb_id,
    status.task_id,
    timeout=300,      # Max wait time in seconds
    poll_interval=5   # Seconds between polls
)

if final.is_complete:
    print(f"Download URL: {final.url}")
else:
    print(f"Failed or timed out: {final.status}")

ChatAPI (client.chat)

ask() Parameters:

async def ask(
    notebook_id: str,
    question: str,
    source_ids: list[str] | None = None,  # Limit to specific sources (None = all)
    conversation_id: str | None = None,   # Continue existing conversation
) -> AskResult

Example:

# Ask questions (uses all sources)
result = await client.chat.ask(nb_id, "What are the main themes?")
print(result.answer)

# Access source references (cited in answer as [1], [2], etc.)
for ref in result.references:
    print(f"Citation {ref.citation_number}: Source {ref.source_id}")

# Ask using only specific sources
result = await client.chat.ask(
    nb_id,
    "Summarize the key points",
    source_ids=["src_001", "src_002"]
)

# Continue conversation
result = await client.chat.ask(
    nb_id,
    "Can you elaborate on the first point?",
    conversation_id=result.conversation_id
)

# Configure persona
await client.chat.configure(
    nb_id,
    goal=ChatGoal.LEARNING_GUIDE,
    response_length=ChatResponseLength.LONGER,
    custom_prompt="Focus on practical applications"
)

ResearchAPI (client.research)

Method Signatures:

async def start(
    notebook_id: str,
    query: str,
    source: str = "web",   # "web" or "drive"
    mode: str = "fast",    # "fast" or "deep" (deep only for web)
) -> dict:
    """
    Returns: {"task_id": str, "report_id": str, "notebook_id": str, "query": str, "mode": str}
    Raises: ValueError if source/mode combination is invalid
    """

async def poll(notebook_id: str) -> dict:
    """
    Returns: {"task_id": str, "status": str, "query": str, "sources": list, "summary": str}
    Status is "completed", "in_progress", or "no_research"
    """

async def import_sources(notebook_id: str, task_id: str, sources: list[dict]) -> list[dict]:
    """
    sources: List of dicts with 'url' and 'title' keys
    Returns: List of imported sources with 'id' and 'title'
    """

Example:

# Start fast web research (default)
result = await client.research.start(nb_id, "AI safety regulations")
task_id = result["task_id"]

# Start deep web research
result = await client.research.start(nb_id, "quantum computing", source="web", mode="deep")
task_id = result["task_id"]

# Start fast Drive research
result = await client.research.start(nb_id, "project docs", source="drive", mode="fast")

# Poll until complete
import asyncio
while True:
    status = await client.research.poll(nb_id)
    if status["status"] == "completed":
        break
    await asyncio.sleep(10)

# Import discovered sources
imported = await client.research.import_sources(nb_id, task_id, status["sources"][:5])
print(f"Imported {len(imported)} sources")

NotesAPI (client.notes)

Example:

# Create and manage notes
note = await client.notes.create(nb_id, title="Meeting Notes", content="Discussion points...")
notes = await client.notes.list(nb_id)

# Update a note
await client.notes.update(nb_id, note.id, "Updated content", "New Title")

# Delete a note
await client.notes.delete(nb_id, note.id)

Mind Maps:

Mind maps are stored internally using the same structure as notes but contain JSON data with hierarchical node information. The list() method excludes mind maps automatically, while list_mind_maps() returns only mind maps.

# List all mind maps in a notebook
mind_maps = await client.notes.list_mind_maps(nb_id)
for mm in mind_maps:
    mm_id = mm[0]  # Mind map ID is at index 0
    print(f"Mind map: {mm_id}")

# Delete a mind map
await client.notes.delete_mind_map(nb_id, mind_map_id)

Note: Mind maps are detected by checking if the content contains '"children":' or '"nodes":'` keys, which indicate JSON mind map data structure.

SettingsAPI (client.settings)

Example:

# Get current language setting
lang = await client.settings.get_output_language()
print(f"Current language: {lang}")  # e.g., "en", "ja", "zh_Hans"

# Set language for artifact generation
result = await client.settings.set_output_language("ja")  # Japanese
print(f"Language set to: {result}")

Important: Language is a GLOBAL setting that affects all notebooks in your account. Supported languages include:

• en (English), ja (日本語), zh_Hans (中文简体), zh_Hant (中文繁體)
• ko (한국어), es (Español), fr (Français), de (Deutsch), pt_BR (Português)
• And over 70 other languages

SharingAPI (client.sharing)

Example:

from notebooklm import SharePermission, ShareViewLevel

# Get current sharing status
status = await client.sharing.get_status(notebook_id)
print(f"Public: {status.is_public}")
print(f"Users: {[u.email for u in status.shared_users]}")

# Enable public sharing (anyone with link)
status = await client.sharing.set_public(notebook_id, True)
print(f"Share URL: {status.share_url}")

# Set view level (what viewers can access)
await client.sharing.set_view_level(notebook_id, ShareViewLevel.CHAT_ONLY)

# Share with specific users
status = await client.sharing.add_user(
    notebook_id,
    "colleague@example.com",
    SharePermission.VIEWER,
    notify=True,
    welcome_message="Check out my research!"
)

# Update user permission
status = await client.sharing.update_user(
    notebook_id,
    "colleague@example.com",
    SharePermission.EDITOR
)

# Remove user access
status = await client.sharing.remove_user(notebook_id, "colleague@example.com")

# Disable public sharing
status = await client.sharing.set_public(notebook_id, False)

Permission Levels:

• SharePermission.OWNER - Full control (read-only, cannot be assigned)
• SharePermission.EDITOR - Can edit notebook content
• SharePermission.VIEWER - Read-only access

View Levels:

• ShareViewLevel.FULL_NOTEBOOK - Viewers can access chat, sources, and notes
• ShareViewLevel.CHAT_ONLY - Viewers can only access the chat interface

Data Types

Notebook

@dataclass
class Notebook:
    id: str
    title: str
    created_at: Optional[datetime]
    sources_count: int
    is_owner: bool

Source

@dataclass
class Source:
    id: str
    title: Optional[str]
    url: Optional[str]
    created_at: Optional[datetime]

    @property
    def kind(self) -> SourceType:
        """Get source type as SourceType enum."""

Type Identification:

Use the .kind property to identify source types. It returns a SourceType enum which is also a str, enabling both enum and string comparisons:

from notebooklm import SourceType

# Enum comparison (recommended)
if source.kind == SourceType.PDF:
    print("This is a PDF")

# String comparison (also works)
if source.kind == "pdf":
    print("This is a PDF")

# Use in f-strings
print(f"Type: {source.kind}")  # "Type: pdf"

Artifact

@dataclass
class Artifact:
    id: str
    title: str
    status: int                     # 1=processing, 2=pending, 3=completed
    created_at: Optional[datetime]
    url: Optional[str]

    @property
    def kind(self) -> ArtifactType:
        """Get artifact type as ArtifactType enum."""

    @property
    def is_completed(self) -> bool:
        """Check if artifact generation is complete."""

    @property
    def is_quiz(self) -> bool:
        """Check if this is a quiz artifact."""

    @property
    def is_flashcards(self) -> bool:
        """Check if this is a flashcards artifact."""

Type Identification:

Use the .kind property to identify artifact types. It returns an ArtifactType enum which is also a str:

from notebooklm import ArtifactType

# Enum comparison (recommended)
if artifact.kind == ArtifactType.AUDIO:
    print("This is an audio overview")

# String comparison (also works)
if artifact.kind == "audio":
    print("This is an audio overview")

# Check specific types
if artifact.is_quiz:
    print("This is a quiz")
elif artifact.is_flashcards:
    print("This is a flashcard deck")

AskResult

@dataclass
class AskResult:
    answer: str                        # The answer text with inline citations [1], [2], etc.
    conversation_id: str               # ID for follow-up questions
    turn_number: int                   # Turn number in conversation
    is_follow_up: bool                 # Whether this was a follow-up question
    references: list[ChatReference]    # Source references cited in the answer
    raw_response: str                  # First 1000 chars of raw API response

@dataclass
class ChatReference:
    source_id: str                     # UUID of the source
    citation_number: int | None        # Citation number in answer (1, 2, etc.)
    cited_text: str | None             # Actual text passage being cited
    start_char: int | None             # Start position in source content
    end_char: int | None               # End position in source content
    chunk_id: str | None               # Internal chunk ID (for debugging)

Important: The cited_text field often contains only a snippet or section header, not the full quoted passage. The start_char/end_char positions reference NotebookLM's internal chunked index, which does not directly correspond to positions in the raw fulltext returned by get_fulltext().

Use SourceFulltext.find_citation_context() to locate citations in the fulltext:

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
    if len(matches) > 1:
        print(f"Warning: {len(matches)} matches found, using first")
else:
    context = None  # Not found - may occur if source was modified

Tip: Cache fulltext when processing multiple citations from the same source to avoid repeated API calls.

ShareStatus

@dataclass
class ShareStatus:
    notebook_id: str                   # The notebook ID
    is_public: bool                    # Whether publicly accessible
    access: ShareAccess                # RESTRICTED or ANYONE_WITH_LINK
    view_level: ShareViewLevel         # FULL_NOTEBOOK or CHAT_ONLY
    shared_users: list[SharedUser]     # List of users with access
    share_url: str | None              # Public URL if is_public=True

SharedUser

@dataclass
class SharedUser:
    email: str                         # User's email address
    permission: SharePermission        # OWNER, EDITOR, or VIEWER
    display_name: str | None           # User's display name
    avatar_url: str | None             # URL to user's avatar image

SourceFulltext

@dataclass
class SourceFulltext:
    source_id: str                     # UUID of the source
    title: str                         # Source title
    content: str                       # Full indexed text content
    url: str | None                    # Original URL (if applicable)
    char_count: int                    # Character count

    @property
    def kind(self) -> SourceType:
        """Get source type as SourceType enum."""

    def find_citation_context(
        self,
        cited_text: str,
        context_chars: int = 200,
    ) -> list[tuple[str, int]]:
        """Search for citation text, return list of (context, position) tuples."""

Type Identification:

Like Source, use the .kind property to get the source type:

fulltext = await client.sources.get_fulltext(nb_id, source_id)
print(f"Content type: {fulltext.kind}")  # "pdf", "web_page", etc.

# List sources by type using .kind property
sources = await client.sources.list(nb_id)
for src in sources:
    if src.kind == SourceType.PDF:
        print(f"PDF: {src.title}")
    elif src.kind == SourceType.MEDIA:
        print(f"Audio/Video: {src.title}")
    elif src.kind == SourceType.IMAGE:
        print(f"Image (OCR'd): {src.title}")
    elif src.kind == SourceType.UNKNOWN:
        print(f"Unknown type: {src.title}")

# List artifacts by type using .kind property
artifacts = await client.artifacts.list(nb_id)
for art in artifacts:
    if art.kind == ArtifactType.AUDIO:
        print(f"Audio: {art.title}")
    elif art.kind == ArtifactType.VIDEO:
        print(f"Video: {art.title}")
    elif art.kind == ArtifactType.QUIZ:

Chat Configuration

class ChatGoal(Enum):
    DEFAULT = 1        # General purpose
    CUSTOM = 2         # Uses custom_prompt
    LEARNING_GUIDE = 3 # Educational focus

class ChatResponseLength(Enum):
    DEFAULT = 1
    LONGER = 4
    SHORTER = 5

class ChatMode(Enum):
    """Predefined chat modes for common use cases (service-level enum)."""
    DEFAULT = "default"          # General purpose
    LEARNING_GUIDE = "learning_guide"  # Educational focus
    CONCISE = "concise"          # Brief responses
    DETAILED = "detailed"        # Verbose responses

ChatGoal vs ChatMode:

• ChatGoal is an RPC-level enum used with client.chat.configure() for low-level API configuration
• ChatMode is a service-level enum providing predefined configurations for common use cases

Advanced Usage

Custom RPC Calls

For undocumented features, you can make raw RPC calls:

from notebooklm.rpc import RPCMethod

async with await NotebookLMClient.from_storage() as client:
    # Access the core client for raw RPC
    result = await client._core.rpc_call(
        RPCMethod.SOME_METHOD,
        params=[...],
        source_path="/notebook/123"
    )

Handling Rate Limits

Google rate limits aggressive API usage:

import asyncio
from notebooklm import RPCError

async def safe_create_notebooks(client, titles):
    for title in titles:
        try:
            await client.notebooks.create(title)
        except RPCError:
            # Wait and retry on rate limit
            await asyncio.sleep(10)
            await client.notebooks.create(title)
        # Add delay between operations
        await asyncio.sleep(2)

Streaming Chat Responses

The chat endpoint supports streaming (internal implementation):

# Standard (non-streaming) - recommended
result = await client.chat.ask(nb_id, "Question")
print(result.answer)

# Streaming is handled internally by the library
# The ask() method returns the complete response
