Kai's verdictA-tier for social/casual. B-tier for serious work. Good entry point.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for academic research. Nothing else comes close for systematic reviews.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
