Which should you choose?

NotebookLM: Google's AI research notebook that answers from sources you upload, with audio overviews.

Perplexity: AI answer engine that searches the web and cites its sources.

The best way to decide is to run the same week of real work through both — most offer a free plan or trial — and compare how long tasks take, what your team prefers, and the total cost for your number of users including renewal pricing.
