Kai's verdictS-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.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
