Cut the silence.
Remove every um.
NoiseZero listens to your recording, finds dead air and filler words like um, uh, and matlab, 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," "matlab," "yaar" 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.
Does it understand Hindi and Indian-accented English?
Yes — the filler list covers Hinglish code-switching (matlab, yaar, haan, na, arre) alongside English fillers, with Tamil and Telugu on the roadmap.
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.
