Which plan to pickStart on Free. If you find yourself rationing the 10 Pro messages, Pro billed yearly is good value at $12 a month. Deep is only for people whose job is literature reviews; most readers here will never need it.Use the free trial for a week, then take Professional. 300 searches on Starter goes in a couple of weeks for most people. Only pay for Ultimate if you'd otherwise pay for an AI chat subscription, since it bundles the top models. Yearly billing saves 10%.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.
