Is NotebookLM worth the price?

84/100

NotebookLM (renamed Gemini Notebook in July 2026) is free for personal use with a 50-source cap per notebook.

Paid limits come only through Google AI plans: Plus at $4.99/mo and Pro at $19.99/mo per Google's student-offer terms. There is no standalone NotebookLM checkout.

This is best for people already in Gemini or Google One.

Hidden Costs & Gotchas

There is no NotebookLM-only SKU. Paid caps ship inside Google AI Plus ($4.99/mo) or Pro ($19.99/mo), which also include Gemini and Drive storage (Google, student-offer terms).

notebooklm.google.com/pricing redirects to Google sign-in. The public plan card is notebooklm.google/plans.

Free is capped at 50 sources per notebook. Plus is 100, Pro is 300, Ultra is 600 (official plans page).

Workspace and Education get it through Google Workspace, not the consumer Plus checkout.
