Kai's verdictA-tier. Best free agentic option in VS Code. Use with Claude for best results.A-tier in its niche. The only one that actually gets emotion right.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.
