Using Selector Lists

Selectors are provided as Python lists of fallback options. Try each in order:

async def try_selectors(page, selectors: list[str], action="click", timeout=5000):
    """Try multiple selectors until one works."""
    for selector in selectors:
        try:
            element = page.locator(selector)
            if action == "click":
                await element.click(timeout=timeout)
            elif action == "fill":
                return element
            return True
        except Exception:
            continue
    raise Exception(f"None of the selectors worked: {selectors}")

# Example usage
await try_selectors(page, HOME_SELECTORS["create_notebook"])

source_data = [
    [file_id, mime_type, 1, title],  # 0: File info

Critical: Edit Icon vs Full Button

# ✅ Click edit icon for customization dialog
await page.locator(".create-artifact-button-container:has-text('Audio') .option-icon").click()

# ❌ Clicking full button starts generation with defaults (skips customization!)
await page.locator(".create-artifact-button-container:has-text('Audio')").click()

RPC: CREATE_ARTIFACT (R7cb6c)

All artifact types use R7cb6c with different content type codes and nested configs.

Mind Map (Type 5) - Uses GENERATE_MIND_MAP (yyryJe)

Source: _artifacts.py::generate_mind_map()

Note: Mind map uses a different RPC method than other artifacts.

# RPC: GENERATE_MIND_MAP (yyryJe), NOT CREATE_ARTIFACT
params = [
    source_ids_nested,                            # 0: [[[sid]] for sid in source_ids]
    None,                                         # 1
    None,                                         # 2
    None,                                         # 3
    None,                                         # 4
    ["interactive_mindmap", [["[CONTEXT]", ""]], ""],  # 5: Mind map command
    None,                                         # 6
    [2, None, [1]],                               # 7: Fixed config
]

RPC: LIST_ARTIFACTS (gArtLc)

Source: _artifacts.py::list(), _artifacts.py::poll_status()

params = [
    [2],
    notebook_id,
    'NOT artifact.status = "ARTIFACT_STATUS_SUGGESTED"',  # Filter string
]

# Response contains artifacts array with status:
# status = 1 → Processing
# status = 2 → Pending
# status = 3 → Completed

Python API Note: artifacts.list() also fetches mind maps from GET_NOTES_AND_MIND_MAPS and includes them as Artifact objects (type=5). This provides a unified list of all AI-generated content. Mind maps with status=2 (deleted) are filtered out.

Notes

RPC: CREATE_NOTE (CYK0Xb)

Source: _notes.py::create()

Note: Google ignores title/content in CREATE_NOTE. Must call UPDATE_NOTE after to set actual content.

# Creates note with fixed placeholder values
params = [
    notebook_id,   # 0
    "",            # 1: Empty string (ignored)
    [1],           # 2: Fixed flag
    None,          # 3
    "New Note",    # 4: Placeholder title (ignored)
]
# Then call UPDATE_NOTE to set real title/content

RPC: UPDATE_NOTE (cYAfTb)

Source: _notes.py::update()

params = [
    notebook_id,                       # 0
    note_id,                           # 1
    [[[content, title, [], 0]]],       # 2: Triple-nested [content, title, [], 0]
]

RPC: DELETE_NOTE (AH0mwd)

Source: _notes.py::delete()

Important: This is a soft delete - it clears note content but does NOT remove the note from the list. The note remains with None content and a status flag of 2.

params = [
    notebook_id,   # 0
    None,          # 1
    [note_id],     # 2: Single-nested note ID
]

# BEFORE delete:
# ['note_id', ['note_id', 'content', [metadata], None, 'title']]

# AFTER delete:
# ['note_id', None, 2]  # Status 2 = deleted/cleared

Note: Same behavior applies to mind maps via delete_mind_map(). The Python API filters out items with status=2 in list() and list_mind_maps() to match UI behavior.

RPC: GET_NOTES_AND_MIND_MAPS (cFji9)

Source: _notes.py::_get_all_notes_and_mind_maps()

params = [notebook_id]

Note/Mind Map Data Structures

Notes and mind maps share the same storage system and are distinguished by content format.

Active Note Structure

[
    "note_id",           # Position 0: Note ID
    [
        "note_id",       # [1][0]: ID (duplicate)
        "content",       # [1][1]: Note content text
        [                # [1][2]: Metadata
            1,           # Type flag
            "user_id",   # User ID
            [ts, ns]     # [timestamp_seconds, nanoseconds]
        ],
        None,            # [1][3]: Unknown
        "title"          # [1][4]: Note title
    ]
]

Active Mind Map Structure

[
    "mind_map_id",       # Position 0: Mind map ID
    [
        "mind_map_id",   # [1][0]: ID (duplicate)
        '{"name": "Root", "children": [...]}',  # [1][1]: JSON with children/nodes
        [metadata],      # [1][2]: Same as notes
        None,            # [1][3]: Unknown
        "Mind Map Title" # [1][4]: Title
    ]
]

Deleted Item Structure (Status = 2)

["id", None, 2]  # Content cleared, status=2 indicates soft-deleted

The Python API:

• notes.list() - Returns only active notes (excludes mind maps and status=2)
• notes.list_mind_maps() - Returns only active mind maps (excludes status=2)
• artifacts.list() - Includes mind maps as Artifact objects (excludes status=2)

Source ID Nesting Patterns

CRITICAL: Source IDs require different nesting levels depending on the method.

Building nesting in Python:

source_ids = ["source_1", "source_2", "source_3"]

# Single: [source_id]
single = [source_ids[0]]

# Double: [[source_id]]
double = [[source_ids[0]]]

# Triple: [[[source_id]]]
triple = [[[source_ids[0]]]]

# Array of Double for artifacts
source_ids_double = [[sid] for sid in source_ids]
# Result: [["source_1"], ["source_2"], ["source_3"]]

# Array of Triple for artifacts
source_ids_triple = [[[sid]] for sid in source_ids]
# Result: [[["source_1"]], [["source_2"]], [["source_3"]]]

params = [
    [
        [
            notebook_id,
            None,                  # no user changes

    None,
    [2]
]

RPC: SET_VIEW_LEVEL (via RENAME_NOTEBOOK s0tc2d)

Source: _sharing.py::set_view_level()

Set what viewers can access (full notebook vs chat only).

Note: This uses the same RPC ID as RENAME_NOTEBOOK (s0tc2d) but with different parameter structure.

# view_level: 0=full notebook, 1=chat only
params = [
    notebook_id,  # 0: Notebook ID
    [
        [
            None, None, None, None,   # indices 0-3
            None, None, None, None,   # indices 4-7
            [[view_level]],           # index 8: [[0]] or [[1]]
        ]
    ],
]

# Response: Full notebook data (same as rename response)

Notebook Sharing Overview

Sharing is a notebook-level setting. When you share a notebook, ALL artifacts become accessible.

Notebooks have three sharing dimensions:

1. Visibility (SHARE_NOTEBOOK - QDyure or SHARE_ARTIFACT - RGP97b):

   • [0] = Restricted (only explicitly shared users)
   • [1] = Anyone with the link

2. View Level (RENAME_NOTEBOOK - s0tc2d):

   • [[0]] = Full notebook (chat + sources + notes)
   • [[1]] = Chat only (viewers can only use chat)

3. User Permissions (SHARE_NOTEBOOK - QDyure):

   • 1 = Owner (read-only, cannot be assigned)
   • 2 = Editor (can edit notebook)
   • 3 = Viewer (read-only access)
   • 4 = Remove (internal: remove user from share list)

Python API:

# Use client.sharing for all sharing operations
status = await client.sharing.get_status(notebook_id)
await client.sharing.set_public(notebook_id, True)
await client.sharing.set_view_level(notebook_id, ShareViewLevel.CHAT_ONLY)
await client.sharing.add_user(notebook_id, "user@example.com", SharePermission.VIEWER)

Share URLs:

• Notebook: https://notebooklm.google.com/notebook/{notebook_id}
• Artifact deep-link: https://notebooklm.google.com/notebook/{notebook_id}?artifactId={artifact_id}

The ?artifactId=xxx parameter creates a deep link that opens the notebook and navigates to that specific artifact. Mind Maps cannot be shared (no public URLs).

Source Refresh Operations

RPC: REFRESH_SOURCE (FLmJqe)

Source: _sources.py::refresh()

Refresh a source to get updated content (for URL/Drive sources).

params = [
    None,           # 0
    [source_id],    # 1: Single-nested source ID
    [2],            # 2: Fixed flag
]

]

# Called with source_path:
await rpc_call(
    RPCMethod.CHECK_SOURCE_FRESHNESS,
    params,
    source_path=f"/notebook/{notebook_id}",

#   URL sources:   [] (empty array) = fresh
#   Drive sources: [[null, true, [source_id]]] = fresh
#                  [[null, false, [source_id]]] = stale
#   Legacy:        True = fresh, False = stale

Note: Mind Maps are NOT shareable (they don't have public URLs).

# share_options: [1] for public, [0] for private
# artifact_id is optional - used to generate a deep-link URL to that specific artifact
params = [
    share_options,  # 0: [1] for public link, [0] for private
    notebook_id,    # 1: Notebook ID
    artifact_id,    # 2: Optional - artifact ID for deep-link URL
]

# Called with source_path:
await rpc_call(
    RPCMethod.SHARE_ARTIFACT,
    params,
    source_path=f"/notebook/{notebook_id}",
)

# Share URL format:
# - Notebook: https://notebooklm.google.com/notebook/{notebook_id}
# - Artifact deep-link: https://notebooklm.google.com/notebook/{notebook_id}?artifactId={artifact_id}

Important: The ?artifactId=xxx URL is a deep link - it opens the shared notebook and navigates to that artifact. The artifact itself isn't independently shared.

RPC: GET_INTERACTIVE_HTML (v9rmvd)

Source: _artifacts.py::_get_artifact_content()

Fetch HTML content for quiz or flashcard artifacts. Used for downloading these artifact types in various formats.

# Called with source_path:
await rpc_call(
    RPCMethod.GET_INTERACTIVE_HTML,
    params,
    source_path=f"/notebook/{notebook_id}",
)

# Response structure:
