NoiseZero: AI Noise Remover

NoiseZero is an audio editor that removes dead air, filler words like "um" and "uh," and background noise — mostly right on your phone, no editing experience needed. It's a silence remover, filler word remover, and noise reduction app built for podcasters, teachers, students, sales teams and anyone who talks for a living.

Load a voice note, lecture, podcast take, or short-form video and get back a tight, confident recording in under a minute.

🔇 SILENCE CUTTER — free, on-device, unlimited
A local, on-device neural VAD (voice activity detection) model finds every dead-air gap the moment you stop recording — no waiting on a server, no internet required. Choose Gentle, Balanced or Aggressive tightness, and every cut is padded and crossfaded so joins never sound choppy or robotic. Free and unlimited for takes under 5 minutes, with no upload and no account needed.

🗣️ FILLER WORD REMOVER — cloud AI "um" and "uh" removal
Cutting filler words needs real speech recognition, not just a volume graph, so this feature runs as cloud AI: your audio is transcribed, and every "um," "uh," "like" and more is shown to you with a running count before a single word is cut. Your recording is deleted immediately after processing — nothing is stored. English filler detection is available today; Hinglish, Tamil and Telugu filler detection are already built and tested, and are coming to the app next.

🎙️ NOISE REDUCTION — local AI denoising
Strips fan hum, traffic noise and room echo using a local, on-device denoising model — the same privacy guarantee as Silence Cutter, since this audio never leaves your phone either. Run it free by watching a rewarded ad, or spend AI Minutes to skip the ad.

LOCAL AI vs. CLOUD AI — where your audio actually goes
NoiseZero is deliberately hybrid, not all-cloud. Silence Cutter and Noise Reduction are 100% local AI, so they work with no internet connection and nothing you record ever leaves your phone. Filler Word Remover is the one feature that uses cloud AI, because reliably catching "um" and "uh" requires real transcription — that's the only place audio is ever sent off-device, and it's deleted right after processing. NoiseZero uses local AI for privacy and speed, and cloud AI only where accuracy requires it.

MADE FOR

Podcasters, teachers, sales teams recording pitches, students recording lectures, and anyone doing voice notes or short-form video who spends more time editing than recording.
