Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for academic research. Nothing else comes close for systematic reviews.A-tier in its niche. The only one that actually gets emotion right.A-tier if you already pay Gemini. B-tier standalone.
