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.B-tier for individuals — Claude does this for less. A-tier for teams needing brand consistency.S-tier in its category.
