AIgis is your personal AI voice butler. Just talk — hands-free, naturally — and ash takes care of the rest. Meet ash, a warm, refined voice companion who actually listens and remembers you. Set reminders, ask for directions, get answers, wind down with a guided meditation, or have ash tell your child a personalized bedtime story — all with your voice, no typing. WHAT ASH CAN DO • Natural voice conversation — just speak, ash replies instantly • Reminders & timers, hands-free • Personalized bedtime stories for kids (by name and length) • Guided meditation with calming full-screen nature scenes • Directions and “where am I?” location help, right in the app • Remembers your name and preferences across conversations THE COUNCIL OF 5 AIs For your hardest questions, ash convenes a Council of 5 AIs — five expert minds that think together to give you a deeper, sharper answer. Watch the screen zoom into the eye as the council deliberates, then ash delivers a single, considered response. SAFETY FIRST — ONE-TAP SOS AIgis includes a built-in SOS. One tap (or just ask ash for help) starts an emergency countdown and can alert your chosen contacts. Peace of mind, always a word away. SPEAKS YOUR LANGUAGE English, French and more — ash adapts to you. AIgis is designed to feel calm, elegant and genuinely helpful — a companion, not just an app. Conditions d'utilisation (EULA) : https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Politique de confidentialité : https://aigis-bkc7.onrender.com/privacy.html
