Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier for designer-led sites. S-tier if animations matter.S-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.S-tier for open-source model APIs. The default in this space.
