what is open-codesign fr?

Open CoDesign is a free, open-source desktop application that lets you turn text prompts into visual designs, prototypes, and documents using AI. You describe what you want in plain English, the app sends that to an AI model of your choice, and the result appears as a live preview. The output can be exported as HTML, PDF, a PowerPoint file, a ZIP archive, or Markdown. The app is positioned as a local-first alternative to cloud-based AI design tools. It runs as an Electron desktop app on your own computer, meaning your data does not pass through a cloud workspace by default. You bring your own API keys for whichever AI provider you use: Claude, GPT-4, Gemini, DeepSeek, Ollama (for locally-run models), or any OpenAI-compatible endpoint. You can also sign in directly with a ChatGPT Plus or Pro subscription to use Codex models without entering a key. Beyond the initial generation step, the app supports iterative refinement. You can click on any element in the preview to drop a comment pin on it, then describe the change you want, and the model rewrites only that region. The app also surfaces a panel of parameters the AI identifies as worth adjusting, such as colors or spacing, so you can tune those without writing another full prompt. Each session is saved locally with a version history. The README compares Open CoDesign directly to Claude Design, v0 by Vercel, Lovable, and Bolt.new, highlighting that it is free to download, runs offline, supports more than 20 model providers, and exports editable files. The project is MIT-licensed and available for Mac, Windows, and Linux.
