Kai's verdictS-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier in the agent category. The first one I'd give to a non-technical friend.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
