Chat with LM Studio, Ollama, and oMLX from your iPhone — or run on-device models offline. Private local AI on hardware you control. No cloud chat subscription required. THREE WAYS TO USE IT 1. On-device — download a model and chat with no internet 2. Connected — LM Studio, Ollama, Jan AI, or oMLX over Wi‑Fi or USB 3. Remote — LM Mini Connect from anywhere, encrypted with your key One app for phone-side models and your desktop local setup. WHAT TO EXPECT Phone models are not the same as huge hosted models in a data center. They are smaller, and that is expected. Performance will vary by hardware. What you gain is control: offline use, private chats on your device or your home machine, and freedom to run the open models you choose. BUILT FOR - People already running LM Studio, Ollama, oMLX or Jan AI who want that stack in their pocket - People who want on-device chat when they are offline or away from Wi-Fi - People who care about keeping conversations off third-party chat servers - Researchers, builders, and privacy-minded users experimenting with local AI INSIDE THE APP - Download and run on-device models on your phone - Connect to LM Studio, Ollama, Jan AI and oMLX - Remote access through LM Mini Connect with your encryption key - Manage and download models on LM Studio from your phone - Local conversation history, folders, and context usage tracking - Personas, plus group chat with up to 5 models in one conversation - Voice chat with Kokoro - Image generation with ComfyUI and Automatic1111 - Web search through SearXNG - Memory so your AI can remember details about you - On-device semantic search across your chats - Background generation, so you don't have to sit and stare at the screen - Themes, backgrounds, and avatars - Import chats from LM Studio - Optional encrypted cloud backups - Custom servers with custom headers - Optional APIs when you want them: OpenAI, OpenRouter, Mistral, DeepSeek, Google Gemini, and more - MCP tool calling - In-app support and feature requests - Dark mode and a chat UI meant for daily use PRIVACY For local use, chats stay on your phone, or between your phone and your own computer.
