Kai's verdictB-tier. Still early. Manus is more flexible for less money.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.S-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.
