Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier for data teams. S-tier if you already live in SQL + Python.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for kids learning. The tutoring UX is legit — not a generic chatbot dressed up.
