Bleeper

Bleeper is a specialized tool that automatically finds and mutes swear words in audio and video files. You upload a podcast episode, interview, music track, or video, and it returns a clean version where profanity is silenced. The core job is censorship for content compliance, but it's designed to do this without ruining the natural sound of the speaker's voice. It handles common formats like MP3, WAV, MP4, and MOV.

What makes Bleeper stand out is its technical approach. It doesn't just run the whole file through a filter. First, it uses AI to separate the vocal track from any background music or noise. Then, it analyzes the isolated speech at the individual word level to detect profanity in both Polish and English. This precision means it can mute only the offending words while leaving the rest of the audio—and the speaker's vocal tone—completely untouched. The system provides a detailed log of every muted word with timestamps and exports broadcast-ready masters alongside SRT subtitle files that mark censored words with [***].

This tool is built for media producers who need reliable, fast censorship. Independent podcasters and YouTube creators use it to keep their content advertiser-friendly and avoid demonetization. For larger operations like TV studios, Bleeper offers a desktop version that runs entirely on local hardware, ensuring no sensitive media leaves the facility. It integrates with professional editing chains from Avid, Adobe, and Dalet, fitting into existing broadcast workflows between ingest and playout.
