Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier. If you're on Vercel/shadcn, this is cheating.A-tier. S-tier if you self-host. The reason open-source image gen matters.S-tier for text-in-image. Use this for posters, Midjourney for art.
