Kai's verdictS-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for fiction. If you're writing a novel, this beats raw ChatGPT every time.
