Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.B-tier. Still early. Manus is more flexible for less money.S-tier for local inference. If you care about privacy or want to tinker, install this today.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
