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 infrastructure. The one platform every AI dev eventually uses.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.B-tier. Still early. Manus is more flexible for less money.
