Frequently Asked Questions (FAQ)
What is Google Sign-In cloud sync?
Log in with your Google account to automatically save your API key, AI persona, language, accent color, memory limit, and search engine settings to Firebase Firestore. On any device, just sign in again and MirAI loads your preferences instantly.
Can I install MirAI as a native app?
Yes! MirAI is a PWA. Install it on Android via Chrome's "Add to Home Screen". Works offline and supports push notifications.
Do I need my own API Key?
For best performance, yes. But the default public key works with limits. Get a free key from Google AI Studio and enter it in settings – it will sync to the cloud if you're logged in.
What file types can I upload?
Images (JPEG, PNG, WebP), audio (MP3, WAV, OGG), and documents (PDF, DOCX, TXT, MD, JSON). Use the '+' menu to attach one file per message.
Is my data secure with MirAI?
Absolutely. Your own API key stays in your browser. Cloud sync uses Firebase secured by Google. .medf backups are AES-GCM encrypted with authenticity signatures.
How does TTS stop work?
While the AI is speaking, click the speaker icon again to immediately stop playback. Clicking again restarts from the beginning.
Can I control chat memory?
Yes! Use the memory slider in Settings to set the maximum messages (25–85). Older messages are trimmed intelligently.
