Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for solo + free. The best free option, hands down.
