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.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Great price/performance. Go here if ElevenLabs is too expensive.
