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.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
