System requirements

RequirementMinimum
Android version6.0 (Marshmallow) or higher
Internet connectionRequired for OpenRouter and cloud providers
Local server modePhone and PC on the same Wi-Fi network
LMSA does not run AI models on your device. For local server mode, the model runs on your PC — your phone only needs to reach it over your home Wi-Fi network. For cloud mode, you need an active internet connection and an API key from your chosen provider.

Free vs. premium

LMSA’s core functionality is available for free. The free tier shows ads. A single one-time in-app purchase through Google Play removes all ads and unlocks every premium feature permanently — there are no subscriptions or recurring charges.

First-launch experience

1

Accept the terms

On first launch, LMSA displays its terms of service and privacy policy. Review and accept them to continue.
2

Complete the setup wizard

LMSA walks you through selecting your AI provider type (local server or cloud) and entering your connection details. You can skip this and configure it later in Settings.
3

Grant permissions (optional)

LMSA may request microphone access for voice input and storage access for file attachments. These are optional — you can grant or deny them and adjust permissions later in Android system settings.
4

Start chatting

Once your provider is configured and a model is selected, you’re ready to send your first message.
Local server connections may be unencrypted. Use LMSA on trusted networks only — avoid connecting to local servers over public or shared Wi-Fi.
