Kai's verdictB-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for model-shopping. I use this for every prototype before committing.A-tier in its niche. The only one that actually gets emotion right.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
