Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.S-tier for solo + free. The best free option, hands down.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
