Kai's verdictA-tier. Great price/performance. Go here if ElevenLabs is too expensive.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.A-tier. Rising fast. If you can tolerate the UX, quality per dollar is best-in-class.
