Kai's verdictS-tier for solo + free. The best free option, hands down.A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier. Still early. Manus is more flexible for less money.
