Kai's verdictB-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.B-tier. Still early. Manus is more flexible for less money.
