Isolait – Voice Isolation

New in this update: transcription, a Lock Screen widget, saved profiles, and patent-pending Direction Lock. Hear one voice, mute the rest.

Every room has a voice worth hearing. Isolait finds it — and mutes everything else.

Isolait is real-time voice isolation that runs entirely on your iPhone. Point your phone at a voice, lock onto it, and hear that person clearly — even in a crowded room, a noisy office, or a busy street. No cloud processing. No uploaded audio. Just a custom AI engine trained specifically for this one job.

VOICE LOCK Tap the mic on any voice and Isolait learns it instantly. From that moment on, everything else — background chatter, music, traffic — fades into the background while your locked voice stays clear.

DIRECTION LOCK (patent-pending) Isolait combines your phone's compass heading with microphone beamforming and voice fingerprinting to isolate not just a voice, but the direction it's coming from. Point, lock, and let Isolait do the rest.

SAVED VOICE PROFILES Save any voice once and Isolait remembers it. Re-lock onto a saved voice instantly — no re-sampling, no waiting, no repeating yourself.

ISOLATED TRANSCRIPTION Get a live transcript of your locked speaker only. Cross-talk and background noise stay out of your notes, not just out of your ears.

LOCK SCREEN CONTROLS Start and stop listening right from your Lock Screen or Control Center — no need to unlock your phone or open the app.

BUILT FOR PRIVACY Isolait's voice model runs entirely on-device. Your voice is never uploaded, streamed, or stored anywhere but your phone.

WHO IT'S FOR

• Meetings and calls: isolate the speaker who matters and keep your notes clean
• Content creators: record podcasts and interviews with studio-cleaner audio, anywhere
• Noisy environments: hold a conversation in a coffee shop, an office, or on the street without straining to hear
• Anyone who's ever said "wait, what?" one too many times in a loud room

Isolait works best when you're focused on a single nearby speaker. Performance in very loud or highly reverberant environments will vary — Isolait is built to help you hear better, not to replace a hearing aid.

Hear it. Understand it. Keep it.
