Kai's verdictA-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.B-tier overall, A-tier if GDPR/data residency matters. Solid backup option.A-tier if you already pay Gemini. B-tier standalone.
