Which should you choose?

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

Speechify: Text-to-speech reader for documents, PDFs and web pages.

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.
