Kai's verdictS-tier. Category-defining UX. If you take notes in meetings, switch this week.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.B-tier. Still early. Manus is more flexible for less money.
