Kai's verdictB-tier. Still early. Manus is more flexible for less money.A-tier in its niche. The only one that actually gets emotion right.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.
