How it works
AI flags it. You decide what gets censored.
An AI profanity filter uses speech recognition to locate spoken words in audio or video, then helps you replace selected moments with a bleep or silence. Unlike a text-only filter, it works from the actual spoken track—but human review still decides the final result. Bleep That Sh*t! provides the browser-local option for short, compatible desktop files.

Speech becomes a timed transcript
Whisper speech recognition turns spoken language into words with start and end times. Those timestamps let the censor treatment line up with the selected audio instead of forcing you to scrub a timeline by hand.
Lists flag likely matches
Built-in and custom lists can use exact, partial, or fuzzy matching. They flag likely problem words for review; they do not make the final decision for you.
You approve every edit
Add or remove selections, choose bleep or silence, and preview the result. Adjust matches before export — you stay in control.
Only the chosen moments change
The selected audio is replaced at its timestamps. For video files, the picture stays intact while the audio track receives the reviewed edits.

Good to know
- Clear spoken audio gives the strongest transcript.
- Accents, slang, noise, singing, and overlapping speakers can reduce accuracy.
- Exact, partial, fuzzy, and manual selection are review tools—not guarantees.

What is an AI profanity filter?
An AI-assisted profanity editor uses speech recognition to create a timed transcript, then compares transcript words with a profanity list. Because transcription and matching can miss context or words, a person reviews the suggestions before applying bleep or silence.
Is there a free AI profanity filter for audio and video?
Yes — Bleep That Sh*t! is a free browser-based AI profanity filter. It uses OpenAI Whisper for transcription, applies built-in profanity lists or your custom selections, and outputs the censored file. Files up to 10 minutes are free; no account needed.
How accurate is an AI profanity filter?
Accuracy varies with audio quality, accents, overlapping speakers, singing, music, and the chosen model. Exact, partial, and fuzzy matching can help find likely transcript matches, but review the full transcript, add missed ranges manually, and preview the export.
Does the AI profanity filter work in real-time?
No. Bleep processes selected files, not live streams. Completion time varies with the file, device or cloud capacity, model, and selected mode; allow additional time for transcript review and export preview.
Can I use the AI profanity filter on videos for YouTube?
Yes. Run your video through the filter before uploading so risky words can be bleeped or silenced. This can help prepare a cleaner version for YouTube, TikTok, Instagram, or classroom use, but platform monetization decisions are still up to each platform.
Is my content private when I use the AI profanity filter?
In browser mode, the media file is not uploaded for transcription or censor rendering. Studio is an upload-based cloud tier for longer files.
