Kai's verdictB-tier. Still early. Manus is more flexible for less money.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.A-tier. No reason not to use it if you're on Figma. Not worth switching for.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.
