|---|---|---|---|
| Plans | Free Free Occasional fact-checking. | Free Free The occasional big question. | Free Free Quick sourced answers and a taste of research mode. |
ProOur pick $20/mo, or $12/mo billed yearly Anyone who checks evidence weekly. | Google AI Plus $4.99/mo Light users who want a bit more headroom. | ProOur pick $17/mo billed yearly Anyone who researches most days. | |
Deep $65/mo, or $45/mo billed yearly Researchers and clinicians doing frequent literature reviews. | Google AI ProOur pick $19.99/mo Anyone who runs a few reports a week or also uses NotebookLM. | Max $200/mo, or $167/mo billed yearly Heavy users who also want the Computer agent and the newest models first. | |
Teams Custom Labs, departments and research groups. | Google AI Ultra From $99.99/mo Power users who want the highest limits across all of Google AI. | Enterprise Pro From $40/seat/mo Teams that need admin controls and shared billing. | |
| Which plan to pick | 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. | Try 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. | 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. |
