Pricing
Plans as listed on each vendor's site when we last checked. Confirm before you buy.
| Attribute | NotebookLM | Perplexity (Research) | Consensus |
|---|---|---|---|
| Plans | FreeOur pick Free Almost everyone. Try this before paying for anything. | Free Free Quick sourced answers and a taste of research mode. | Free Free Occasional fact-checking. |
Google AI Plus $4.99/mo People who hit the free limits now and then. | ProOur pick $17/mo billed yearly Anyone who researches most days. | ProOur pick $20/mo, or $12/mo billed yearly Anyone who checks evidence weekly. | |
Google AI Pro $19.99/mo Heavy users who also want Gemini Pro and Deep Research. | Max $200/mo, or $167/mo billed yearly Heavy users who also want the Computer agent and the newest models first. | Deep $65/mo, or $45/mo billed yearly Researchers and clinicians doing frequent literature reviews. | |
Google AI Ultra From $99.99/mo Power users who want the top of everything Google offers. | Enterprise Pro From $40/seat/mo Teams that need admin controls and shared billing. | Teams Custom Labs, departments and research groups. | |
| Which plan to pick | 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. | Pro is the one. The free plan is too tight to judge research mode properly, and Max only makes sense if you want the Computer agent or you hit Pro limits every day. Businesses with a few people on it should look at Enterprise Pro for the admin controls. | Start 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. |
