Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds.B-tier. Still early. Manus is more flexible for less money.
