Kai's verdictS-tier for coding. If you write code of any kind, this pays back the $20 in a day.S-tier for academic research. Nothing else comes close for systematic reviews.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.B-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.
