Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for model-shopping. I use this for every prototype before committing.A-tier. Best of a boring category. Use it for first drafts, then edit in Keynote if high-stakes.A-tier in its niche. The only one that actually gets emotion right.
