Chat with the AI models
already running on your PC.

LMSA stands for Local Model Smart Assistant. It is an Android app that lets you chat with AI models from your phone using LM Studio or Ollama on your local network, or cloud models through OpenRouter and any OpenAI-compatible custom endpoint. For setup details, check our Support page.

Yes. LMSA Premium includes a hands-free Voice Mode for real-time voice chat with local LLM models running on LM Studio or Ollama. Speak naturally and LMSA transcribes your voice on-device, sends the text to your local model, and reads the reply back out loud, with no cloud voice service involved. See our Privacy-First Voice Mode page for setup details.

Yes, in two ways. LM Studio and Ollama normally require your Android device and your local server to be on the same trusted network, so by default they only work when you’re home. To use LMSA away from home, either switch to OpenRouter, which works over the internet with no local network needed, or set up Tailscale for secure remote access to your local server.

Yes, all chat history saved on your Android device is encrypted, regardless of which provider you use. Encryption in transit depends on the provider: yes, with OpenRouter, all data sent to and from LMSA is always encrypted in transit; no, with a local server provider (LM Studio or Ollama), the LAN connection to your computer is not encrypted, which is normal for local networks, so only use them on networks you trust. If you enable the optional Web Search, your queries go to Brave Search, which states it does not build personal search profiles. See our Privacy Policy for full details.

Zero Data Retention (ZDR) is a policy offered by OpenRouter for select models, where the model provider processes your chats entirely in temporary memory (RAM) and immediately deletes them when done, ensuring your data is never stored, logged, or used for training. It is not a feature created or guaranteed by LMSA — LMSA automatically routes to ZDR-enabled endpoints where OpenRouter offers them, marking these supported models with a green shield icon. Please note that Zero Data Retention of cloud endpoints is separate from data retention on your local device; your chat history and files may still be saved and retained locally on your device. Learn more in OpenRouter’s ZDR documentation.

LMSA includes an optional Web Search powered by Brave Search for real-time context from the live web. Brave Search runs its own independent index and is built for privacy: it doesn’t track your queries, save your search history, or build personal profiles. Queries are sent over secure HTTPS, and LMSA never attaches personally identifiable information, so your searches stay private and anonymous. See Brave Search’s FAQ for more details.

Yes, using LMSA’s dedicated Offline Mode, a Premium-only feature ($14.99 one-time purchase). With Offline Mode enabled and LM Studio or Ollama running on your local network, your Android device just needs to join the same Wi‑Fi as your computer to chat with local models with zero internet connection required. Cloud features (OpenRouter, Web Search) and model downloads/updates still require internet, and free-tier users do not have access to Offline Mode. View the full comparison on our pricing page.

Yes. LMSA is free to download and use, with access to local backends (LM Studio, Ollama) and OpenRouter. Free-tier users see ads, which help fund ongoing development. A one-time $14.99 Premium purchase removes ads and unlocks advanced features like custom endpoint usage, text-to-speech, custom templates, and more. Check the Pricing page for details.

Purchase the Premium lifetime license — a one-time fee of $14.99 with no subscriptions or recurring charges — to remove all ads. Check the Pricing page for details.
