NotebookLM CLI (nlm)

Manage Google NotebookLM notebooks, sources, notes, chat, and generated content (audio/video overviews, slide decks, apps, reports) via the nlm command-line tool.

Requires: nlm on PATH (nix-managed, built from upstream tmc/nlm). Install/update via cd ~/nix && nix run .#build-switch.

Check: command -v nlm || echo "MISSING: nlm CLI not installed"

Command structure: the CLI uses subcommand groups — nlm <group> <action> (e.g. nlm notebook list, nlm source add, nlm audio create). The older flat aliases (nlm list, nlm add, nlm audio-create, …) were removed in upstream's parser migration. When unsure of exact syntax, run nlm --help or nlm <group> --help — it's authoritative. The references/*.md files predate the migration and may be stale.

Authentication

Before first use, authenticate with Google:

nlm auth login -all

This connects to Chrome via CDP (Chrome DevTools Protocol) to extract cookies from an active NotebookLM session. Credentials are stored in ~/.nlm/env.
