About Open Minis
Open Minis is a free, open-source AI agent designed for iOS and Android that transcends standard chatbot limitations by equipping the model with a fully functional computer environment directly on your mobile device.
Unlike traditional conversational interfaces, Open Minis operates a sandboxed Alpine Linux shell natively on your phone. This allows the AI to install packages, execute Python scripts, modify actual files, and even drive a browser. To maximize utility, the app features over 30 native bridges that connect with vital device frameworks like HealthKit, HomeKit, Calendar, and Photos.
With a 'Bring Your Own Model' approach, users can plug in their preferred LLM endpoints—including Claude, GPT, Gemini, Kimi, Grok, or any OpenAI-compatible endpoint. Because everything operates locally with keys and data staying entirely on your phone, Open Minis delivers an open, private, and highly secure AI automation experience.
