Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier in its niche. The only one that actually gets emotion right.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
