Kai's verdictS-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.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.
