|---|---|---|---|
| Plans | Free Free Seeing what a report looks like. | Free Free Occasional fact-checking. | Free Free The occasional big question. |
Go $8/mo Casual users who want more chat, not more research. | 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. | |
PlusOur pick $20/mo Anyone who wants deep research weekly. | 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. | |
Pro From $100/mo Heavy users who run research daily. | 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. | |
| Which plan to pick | If you have Plus already, you are set; its deep research allowance covers most people. Do not buy ChatGPT just for research unless you also want the rest of it, because Perplexity Pro costs less and is faster. Pro is only worth it if you run reports every day. | 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. |
