Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
