Which plan to pickTry the free plan first; it is enough to see the style of report you get. If you want it weekly, Google AI Pro is the pick because the Pro model writes better reports and the same subscription upgrades NotebookLM and Gemini in Gmail and Docs.Stay on Free until it stops you doing something. If that happens, Google AI Pro is the sensible step because it also upgrades Gemini and Deep Research, which you will probably want anyway. AI Plus is a cheap middle step if NotebookLM is all you care about.Start free. The monthly $10 of credit is plenty for one person using it from Claude Code, and if you do run out you only pay for what you use. Enterprise is for software companies, not for a business that just wants better search.

Pros and cons

AttributeGemini Deep ResearchNotebookLMExa
Pros
  • You can edit the plan before it runs, so fewer wasted reports
  • Reads more pages than Perplexity and lists every source
  • Can include your Gmail and Drive in the research
  • Free plan includes it, and Pro is good value for Workspace users
  • Audio Overviews and Canvas make the output easy to share
  • Answers only from your sources and cites the exact passage
  • Free plan is big enough for most small businesses
  • Accepts PDFs, Docs, websites, YouTube and audio as sources
  • Audio Overviews are a clever way to get people to engage with research
  • Simple enough that you can hand it to anyone on the team
  • Finds pages by meaning, so vague descriptions still work
  • Free credit resets every month and needs no card
  • Hosted connection for Claude Code takes minutes to set up
  • Returns clean page text ready for an AI to read
  • Pay as you go with no subscription
Cons
  • Reports are long and often repetitive; plan to edit
  • Can take ten minutes or more per run
  • Free limits are not published as a number, so you find them by hitting them
  • Quieter on citation quality than Perplexity; weak sources slip in
  • Will not research the open web unless you explicitly ask it to find sources
  • Answers can be surface-level on dense material; you still need to read the key parts
  • Audio Overviews take a few minutes and sound alike after a while
  • No way to script or automate it; everything happens in the browser
  • Not much to use on its own; you need Claude or another assistant in front of it
  • Setup assumes some comfort with plugins or settings files
  • Per-request pricing is hard to predict if an agent runs away with searches
  • No mobile or desktop app, because it is a service rather than a product
