Kai's verdictS-tier infrastructure. The one platform every AI dev eventually uses.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier. Category-defining UX. If you take notes in meetings, switch this week.B-tier. Still early. Manus is more flexible for less money.
