Kai's verdictB-tier. Solid product but crowded market. Try it if Notion AI feels too generic.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. S-tier if you self-host. The reason open-source image gen matters.
