notebooklm-py — NotebookLM CLI + Python API Skill

Main

• Treat auth as a first-class step: run notebooklm auth check --test after login, and keep a known-good storage state for CI/headless usage.

• Start with a small notebook + 1–2 sources, then add generate / download flows only after you can reliably ask with citations.

• Because this is an unofficial wrapper over undocumented APIs, pin versions in automation and expect breakage; keep troubleshooting links near your runbooks.

Source-backed notes

• README explicitly warns it is unofficial and uses undocumented Google APIs that may break without notice.
• README shows CLI flows: create/use notebooks, add sources, ask questions, generate artifacts, and download outputs (MP3/MP4/PDF/PNG/CSV/JSON/Markdown).
• README notes a browser-based login via Playwright Chromium and includes a size/time hint for the Chromium install (~170MB; ~30–90s).

FAQ

• Is this affiliated with Google?: No — README says it’s unofficial and not affiliated with Google.
• Can I use it headless?: Yes — README documents cookie/storage-state based auth paths, but you should validate with auth check.
• What breaks most often?: Auth and internal endpoints; pin versions and keep troubleshooting docs handy.
