Kai's verdict	B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.	A-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.	S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.	A-tier for real-time. B-tier for everything else. Worth checking when news breaks.
