Kai's verdictA-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for text-in-image. Use this for posters, Midjourney for art.S-tier for realtime. If latency matters more than voice catalog, start here.
