Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
