Kai's verdictA-tier. Beautiful UX. The writing app I'd pick if I only wrote long-form.A-tier. Best free agentic option in VS Code. Use with Claude for best results.B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code.
