Kai's verdictA-tier for real-time. B-tier for everything else. Worth checking when news breaks.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. Great price/performance. Go here if ElevenLabs is too expensive.
