Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier if you're on Mac. The fastest way to get AI answers without context-switching.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.
