Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.A-tier for social/casual. B-tier for serious work. Good entry point.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.
