Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for realtime. If latency matters more than voice catalog, start here.B-tier. Solid product but crowded market. Try it if Notion AI feels too generic.
