Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.B-tier. Still early. Manus is more flexible for less money.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
