Kai's verdictA-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.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.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.
