Kai's verdictS-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.B-tier. Still early. Manus is more flexible for less money.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
