LMSA – Private AI Chat App: Local LLM, Voice Chat, Ollama, LM Studio & OpenRouter for Android
Turn your Android phone or tablet into a powerful, private AI assistant. LMSA is a local LLM chat app and voice assistant that connects to on-device AI servers like LM Studio and Ollama, or cloud models via OpenRouter — so you can chat or talk with the world's best AI chatbots privately, securely, and completely on your terms.
Run DeepSeek, Llama 3, Mistral, Phi, Qwen, Claude, or Gemini — LMSA is the fastest, cleanest, and most private way to use AI on Android, whether you want a fully offline AI chatbot or instant access to cloud LLMs.
