In a crowded room, isolait finds the one voice you came for — and quiets everything else. Real-time. On-device. It never leaves your phone.
Every feature runs locally on Apple's Neural Engine — there's no server in the loop, no upload, and no delay.
Tap the mic to sample any voice nearby. Isolait captures a unique voice fingerprint in seconds, then locks onto that speaker — filtering out background noise and every other conversation in the room.
Point your phone at the person you want to hear. Isolait blends your device's heading with real-time audio processing to bias toward your target, even in crowded, multi-speaker environments.
Watch your audio environment come alive with a real-time visualizer — see exactly what's coming in, and exactly what isolait is sending back out.
Isolait runs entirely on-device using Apple's Neural Engine. No audio is ever uploaded, stored, or shared — what you hear stays with you, full stop.
Most "AI" voice tools mean a round trip to a server. Isolait's neural pipeline runs entirely on your iPhone — your audio is processed and discarded locally, every time.
The first release proved the full pipeline end-to-end on a real iPhone, in real noise — not a prototype.
A live audio pipeline separates voice-range signal from ambient noise as it happens — no lag, no buffering.
Once locked, isolait holds onto that speaker's fingerprint through movement, crosstalk, and changing background noise.
Your phone's heading helps bias toward whoever you're physically facing — useful the moment you walk into a noisy room.
The core engine is just the beginning. We're building toward something bigger — and every chapter ships when it's ready, not before.
Voice Lock gets more precise, and isolait becomes something you'd actually keep running in your pocket all day.
Isolait starts understanding more than just one voice at a time.
The same engine, built to go wherever your voice needs to follow.
