Frequently Asked Questions (FAQ)
What is the .medf file format?
.medf (MirAI Encrypted Data Files) is an original encrypted data format by Allwaysever for secure backup of chat history, settings, and API keys. It features password protection, authenticity signatures, and cross-device compatibility.
Can I install MirAI as a native app?
Yes! MirAI is a Progressive Web App (PWA). You can install it on Android devices through Chrome's "Add to Home Screen" feature. It works offline and supports push notifications via OneSignal integration.
Do I need my own API Key?
For the best performance and security, we highly recommend using your personal Google Gemini API Key. The default public key has usage limits. You can get a free API key from Google AI Studio and enter it in MirAI's settings.
What AI models does MirAI support?
MirAI supports both Gemini 2.5 Flash (stable) and Gemini 3 Flash Preview (beta) models. You can switch between them via URL parameters or settings. Each model offers different strengths in speed, accuracy, and capabilities.
Is my data secure with MirAI?
Absolutely. When using your own API key, all conversations happen between you and Google's servers. The .medf backup system uses military-grade encryption (Web Crypto API). Your API key is never transmitted to Allwaysever servers - it stays in your browser.
How does the search system work?
The /search command can use external search engines (SearchAPI.io, Google, DuckDuckGo, Wikipedia) if configured, or fallback to AI knowledge base. You can enable/disable engines in Settings → Search Configuration. Search results are cached for speed.
Can I control how much chat history is saved?
Yes! Use the memory slider in Settings to set the maximum number of messages to keep. Older messages are automatically trimmed to maintain performance.
