Apfel Chat – Private on Device AI That Works in Airplane Mode (MIT) (apfel-chat.franzai.com)

MIT has launched Apfel Chat, a revolutionary AI chat application that operates entirely on Mac devices without an internet connection, API keys, or sign-up requirements, ensuring maximum user privacy. Unlike major AI models like ChatGPT, Claude, and Gemini, which rely on cloud servers and user accounts, Apfel Chat allows users to engage in conversations with an on-device language model powered by Apple's iChip, making it an ideal solution for those who prioritize data security and offline functionality. The app features a user-friendly interface that supports voice input, image analysis via Apple Vision, and markdown rendering. Conversations are saved locally in SQLite, allowing users to easily resume chats at their convenience. By handling image reading on-device without AI processing, Apfel Chat enhances privacy while delivering real-time responses. This free, open-source app is designed for users who seek a full AI chat experience without compromising their data or incurring monthly fees, marking a significant step towards local, secure AI solutions in the tech community.
