In a crowded room, isolait finds the one voice you came for, follows it, captions it, and remembers it next time — all without a single byte leaving your phone.
Free · Requires iOS 16.0 or later
The same walkthrough that's built into the app — two voices talking at once, then one voice, alone.
"Hey are we still on for coffee tomorrow morning? I was hoping nine, maybe ten o'clock would work for you."
"So, then he told me the meeting got moved to Thursday. Now I have to rearrange my entire afternoon."

This loops automatically — the real app times it to your own voice, not a fixed clock.
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 combines your device's heading with microphone beamforming and voice fingerprinting to isolate not just a voice, but the direction it's coming from. Currently supported on your iPhone's built-in mic; AirPods support is coming in a future update.
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.
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. Transcribed entirely on-device, with nothing sent anywhere to make it happen.
Transcripts now note who's speaking, so interviews and multi-voice recordings are easier to follow after the fact. Early beta, still improving.
Lock a voice once and keep it. Isolait remembers the voices that matter so you can drop back into a lock in a tap, no re-sampling required.
Switch between your iPhone's mic, AirPods, or any connected Bluetooth headset right in the app — isolait detects what's available and adapts to whichever one you're using.
See who's locked in and control isolait right from your lock screen or AirPods — no need to keep the app open or your phone unlocked.
Say "Hey Siri, start listening" to lock in hands-free, or tap a Home Screen widget to jump straight into a lock — isolait meets you wherever you already are.
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.
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.
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.
V1.2 is out — better audio quality, more reliable transcription, and a first look at speaker-labeled transcripts.
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.
When someone else cuts in, isolait's recovery is noticeably quicker now — roughly half the time to fully re-lock onto your target voice.
Every word from your locked-in voice appears as text in real time — transcribed on your phone, never sent anywhere else. This release improves transcription reliability.
Transcripts now note who's speaking, so multi-voice recordings are easier to follow. Early beta, still improving.
Pick between your iPhone's built-in mic, AirPods, or any connected Bluetooth headset — isolait detects what's plugged in and lets you switch on the fly.
Build a personal library of voices you've locked before, and drop back into them instantly — no re-sampling required.
Lock screen and AirPods controls let you see who's locked in and pause or resume without unlocking your phone. Say "Hey Siri, start listening" for a hands-free lock, or tap the Home Screen widget to jump straight in.
The live lock-strength meter shows up in caption/reader view too, instead of being hidden behind the transcript.
Your phone's heading helps bias toward whoever you're physically facing — useful the moment you walk into a noisy room. For now, Direction Lock is limited to your iPhone's built-in mic; AirPods support is coming in a future update.
The core engine is just the beginning. We're building toward something bigger — and every chapter ships when it's ready, not before.
A guided first launch and per-device tuning, so isolait locks in perfectly whether you're on your phone's mic or your headphones.
Isolait starts understanding more than just one voice at a time — tracking and separating multiple speakers as a conversation moves around you.
Record a room instead of just one voice, then pull any single speaker back out of it afterward, cleanly.
The same engine, built to go wherever your voice needs to follow.
