Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier if you already pay Gemini. B-tier standalone.B-tier. Still early. Manus is more flexible for less money.
