Kai's verdictS-tier. If you're on Vercel/shadcn, this is cheating.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.S-tier for text-in-image. Use this for posters, Midjourney for art.
