| Attribute | ChatGPT Deep Research | Consensus | Exa |
|---|---|---|---|
| Plans | Free Free Seeing what a report looks like. | Free Free Occasional fact-checking. | FreeOur pick Free Personal use inside Claude Code. |
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. | Pay as you go From $4 per 1,000 searches Anyone whose usage outgrows the free credit. | |
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. | Enterprise Custom Companies building products on top of it. | |
Pro From $100/mo Heavy users who run research daily. | Teams Custom Labs, departments and research groups. | ||
| 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. | 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. |
