iPhone
Every AI app you use sends your conversations to someone's server. microAI does not. Your words stay on your iPhone, always.
microAI is a fully offline, private AI assistant powered by real on-device language models. No cloud. No tracking. No subscription. Just powerful AI that runs entirely on your device.
WHY microAI
100% Private by Design
All conversations are processed and stored locally on your device. Nothing is ever transmitted to any server, not even anonymized data.
Truly Offline
Works without Wi-Fi or cellular. On a plane, in a basement, anywhere, your AI assistant is always available.
Semantic Memory
microAI remembers what matters. Our enhanced vector-based memory system recalls your past conversations with semantic understanding, not just keyword matching.
Thermal Intelligence
The only AI app with a real-time device temperature monitor. When your iPhone runs hot from heavy AI processing, microAI alerts you, protecting your device during long sessions.
Vision and Image Recognition
Describe, analyze, or ask questions about any image directly in chat. Supported on select multimodal models.
