Kai's verdictA-tier. The Deep Research feature is genuinely useful. Don't sleep on it if you're already paying Google.A-tier. Best free agentic option in VS Code. Use with Claude for best results.S-tier for content creators. Cuts editing time in half. Non-obvious but life-changing.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.
