User reviews
We evaluated NotebookLM against two hosted alternatives. It won on cost-per-output but lost on latency. For batch work it is a clear yes.
Solid for zero-hallucination document research & conversational audio overviews. The learning curve is real but the payoff is there. Start with the smaller build first.
The output reads naturally once you tune the prompt. It has cut my first-draft time roughly in half.
Clean interface, consistent results once you land on a prompt you like. Wish there were more export presets for client handoffs.
