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. The most interesting spreadsheet in years. Great for ops dashboards.S-tier for price/performance. A-tier for consumer use. If you build apps, this is the budget pick.
