CometAGENT
FreemiumFree; Pro $20/mo
EDITOR’S TAKE · FAISAL SALEEMComet is the most convincing case yet that the browser itself is the next AI battleground: the agent isn't a sidebar bolt-on, it's woven into how you browse, and it genuinely completes multi-step tasks across tabs. It's now free and runs your Chrome extensions, so trying it costs nothing. Whether you switch full-time depends on how much you trust an agent with your logged-in sessions — but as a research and task browser, it's a real step beyond Chrome-plus-a-chatbot.

BUYER’S GUIDE
How to choose an AI search & research tool
Pricing per active user, not per seatVendor sites often show seat pricing, which understates real cost when seats sit unused. Multiply by your active-user count.
Agent vs assistantAn agent plans and runs multi-step tasks; an assistant answers one prompt at a time. 2 of these ship an agent.
Free-tier limits and card requirementsSome “free” tiers ask for a card and bill you past a soft limit. Test the free tier without a card on file.
Changelog and update cadenceAI tools age fast. A vendor that hasn't shipped meaningfully in 6 months is usually about to be lapped.
