Kai's verdictS-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.B-tier. Still early. Manus is more flexible for less money.A-tier. Best free agentic option in VS Code. Use with Claude for best results.
