Kai's verdictA-tier for non-native English speakers. B-tier if your English is already strong — Claude does better with tone.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
