Kai's verdictS-tier all-rounder. If you want one tool that does everything okay-to-great, this is it.A-tier. The best open model for Vietnamese + Chinese. Don't sleep on it if you work in SEA.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
