Kai's verdictA-tier in its niche. The only one that actually gets emotion right.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
