Built by one developer
who needed better tools.
AppVexis Labs is an independent product studio building focused AI utilities for audio and video creators.
Prashant Kumar
Founder & Developer21-year-old B.Tech IT student at NEHU, Shillong. I started AppVexis Labs because I kept running into the same problem — cleaning up audio from recordings made in untreated rooms with cheap mics. Every tool I found was either too expensive, too complicated, or degraded the voice.
So I built Noise Remover. One upload, clean speech back. No plugins, no timeline sync headaches, no re-encoding video. It does one thing and does it well.
Why this exists.
Most recordings don't need a complex multitrack audio suite. They need a fast, dependable first pass that strips background noise and delivers clear speech. Existing tools are either bloated DAW plugins, limited web toys with tiny file caps, or services that quietly keep your media.
Noise Remover handles files up to 1 GB and 2 hours. It processes video without re-encoding — your 4K color grade, framerate, and bitrate come back untouched. Billing is transparent: 1 credit = 1 minute, metered to the exact second. Files are purged after download.
Noise Remover is the first tool on a shared platform. The authentication, billing, storage, and compute infrastructure is built to add new specialized utilities under one account and one credit pool — without bloating the tools you already use.
How we build.
Three commitments that shape every tool.
One job, done well
Each tool solves one problem with precision. No bloated interfaces, no unnecessary knobs or settings you'll never touch.
No games with pricing
No fake progress bars, no hidden charges, no rounding up your usage. What you see is what the system actually bills.
Your files stay yours
Media is never used to train models or shared with third parties. Processing is ephemeral and storage is short-lived.
