Quick decision
NotebookLM is the better tool when your evidence set is already known. Use Perplexity or conventional search to discover sources, then use NotebookLM to question and organise the material you have deliberately selected.
Where the first option earns its place
NotebookLM is unusually useful because it starts with your sources rather than the open web. It can turn documents into cited answers, study aids, audio, video and structured outputs without pretending that every topic belongs in a general chatbot.
A workflow that produces evidence
Create one notebook per decision or project, name every source clearly, exclude weak material, ask questions that require comparisons, and open each citation before carrying a claim into final work.
Privacy, accuracy and review
Do not upload confidential, personal or licensed material until the service terms and your organisation permit it. Generated claims, code, transcripts, images and translations need the same review they would receive from a human contributor.
How to choose without overbuying
Start with the free tier or shortest trial. Use one representative task, define a pass condition and compare the finished result.
