What is MulmoChat
MulmoChat is a groundbreaking research prototype developed by former Microsoft engineer Satoshi Nakajima that reimagines traditional chat interfaces. Unlike conventional text-based chat applications, MulmoChat represents a new paradigm for multimodal AI chat experiences by unifying GUI (Graphical User Interface) and NLUI (Natural Language User Interface). The project is open-source and requires OpenAI and Google Gemini API keys to function, supporting Windows, macOS, and Linux platforms.
