Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.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.S-tier inside Photoshop (Generative Fill). B-tier standalone.
