In simple English
This program turns your written ideas into polished visual prototypes and slide decks. It runs as a desktop app on your own computer. You bring your own API key for an AI provider or sign in with an existing subscription. It does not lock you into a single company or cloud service. It is free to use under an open-source licence.
What it is
Open CoDesign is an open-source desktop application that generates design prototypes, web pages, and slide decks from natural language prompts. It connects to multiple AI providers including Anthropic, OpenAI, Google Gemini, and local models via Ollama.
