Kai's verdictS-tier for reasoning and writing. If you only pay for one chatbot, pay for this one — especially for long work.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.B-tier. Still early. Manus is more flexible for less money.
