🔒

Privacy First

All data stays on your device. No servers, no cloud, no telemetry. Conversations are encrypted locally and never leave your phone.

⚡

Fully Offline

Works without internet. Airplane mode? Still running. Perfect for travel, low-connectivity areas, or just peace of mind.

🎤

Voice Mode

Talk naturally with Muse using offline speech recognition and text-to-speech. No audio is ever sent anywhere.

🎨

Multiple Personalities

Choose from Calm Mentor, Logical Thinker, Creative Muse, or Friendly Companion. Each brings a unique style.

📈
