Kai's verdictS-tier for academic research. Nothing else comes close for systematic reviews.A-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.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.
