Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.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.S-tier for speed. When latency is the product, start here.
