Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for local inference. If you care about privacy or want to tinker, install this today.B-tier. Still early. Manus is more flexible for less money.
