Browser Silence Cutter

Free in-browser removal of silences and filler words, zero upload

Problem

Amateur podcasters and video creators need to cut silences and filler words, but existing tools are paid, require cloud uploads, or demand installation. Many are privacy-sensitive and don't want unpublished media on third-party servers.

Solution

A fully local browser tool that detects and removes silence segments and filler words from video. Upload, auto-detect, trim, and export—no backend API, no account, works in Chrome/Edge.

Users

Amateur podcasters, YouTubers, online course instructors, privacy-conscious creators

MVP

Local audio track analysis for silence detection; WebAudio-based filler word detection with extendable word list; timeline preview and manual fine-tuning; export trimmed video; zero-upload privacy promise page

Revenue

Free basic tier + one-time Pro license ($19) for batch processing, custom word lists, and higher export resolution; or export-time credits

Why now

Browser WASM and media processing are now powerful enough, and creator privacy concerns about cloud uploads keep rising; an indie pure-frontend build is feasible fast
