Cut the silence.
Remove every um.
NoiseZero listens to your recording, finds dead air and filler words like um, uh, and like, and removes them automatically — on-device, free, and private.
3 flagship tools. One sleek app.
Engineered for creators who need fast, tight voice notes, lectures and reels — without opening a desktop DAW.
Silence Cutter
Finds every dead-air gap with an on-device neural VAD model — Gentle, Balanced or Aggressive tightness, adaptive crossfades, zero choppy joins. Free and unlimited under 5 minutes, no upload.
Noise Remover
Strips fan hum, traffic and room echo. Get an instant Studio-quality pass in the cloud — watch a rewarded ad, or spend AI Minutes — or run it free, fully on-device.
Filler Remover
Server-side speech recognition catches "um," "uh," "like" and more, shown with counts so you approve every word before it's cut — deleted right after processing.
Frequently asked questions
The seven things people actually ask before installing an app that touches their recordings — something else? Email us.
Does silence cutting work without internet?
Yes. Silence detection runs entirely on your phone using an on-device model — no upload, no account, no data leaving your device.
Will my voice sound robotic after the cuts?
It shouldn't. Every cut keeps a little breathing room, pads around each edit, and crossfades the join — the goal is a tighter version of you, not a chopped one.
What languages does filler-word detection support?
English for now. Hinglish, Tamil and Telugu are already built and tested — they're next on the roadmap, not just a someday idea.
Is my audio stored on your servers?
No. Audio uploaded for AI filler detection is processed and deleted immediately afterward — it's never kept.
What file types can I import?
M4A, MP3, WAV, AAC, OGG and Opus, up to 60 minutes per file.
Can I send the result straight to WhatsApp?
Yes — export and share in one tap to WhatsApp, Telegram, Drive or Gmail.
How does AI filler removal get priced?
In minutes, not confusing credits. The free plan includes a two-minute trial; Pro plans include a monthly minute allowance that rolls over on the annual plan.
