KilnNotebookLM is the rare Google AI product with a crisp job: put documents in, ask questions, get answers tied to those pages. Audio overviews are a bonus, not the product. It will not replace Perplexity for the live web or Cursor for a repo. Students and researchers who drown in PDFs should start here before buying another “AI notes” SaaS. Limits depend on the Google AI bundle. Verified 18 Sep 2026.
