Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
