What we love
- ✓Citations land on the exact passage, not a hand-wavy see-source
- ✓Audio Overview format is genuinely novel
- ✓Free tier is generous compared to alternatives
Where it falls short
- −Cannot use the open web — sources only
- −Output is read-only, no in-line edits or comments
- −Privacy story is fine for personal use but enterprise teams will want NotebookLM Plus

Why we picked it
NotebookLM is what every chat-with-your-docs tool wanted to be. The Audio Overview alone is worth the visit — turning a 200-page document into a 12-minute podcast is genuinely useful.
