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.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. The most interesting spreadsheet in years. Great for ops dashboards.
