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.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.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%.
