Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier in its niche. The only one that actually gets emotion right.S-tier for coding. If you write code of any kind, this pays back the $20 in a day.
