AI PROFANITY FILTER
Automatic Profanity Detection for Audio & Video
Upload an audio or video file. AI speech recognition transcribes it with word-level timestamps, built-in profanity lists flag likely problem words, and you review each match before choosing bleep or silence. Free browser mode, no download.
On a phone? Use Studio for cloud transcription instead of asking your mobile browser to run the AI model locally.

An AI profanity filter uses speech recognition to detect spoken swear words in audio or video, then replaces them with a bleep sound or silence. Unlike traditional text-based filters, an AI filter understands actual spoken language — including accents, slang, and natural pacing. Bleep That Sh*t! can run locally in browser mode via WebAssembly for short desktop files. No download or account required for browser mode.
HOW AI PROFANITY FILTERING WORKS
Step 1 — Speech recognition
Traditional profanity filters match text against a word list. That works for chat but not audio. AI profanity filters use a speech recognition model (Whisper) trained on hundreds of thousands of hours of audio, so they understand actual spoken language — including accents, slang, and natural pacing.
Step 2 — Word-level timestamps
Whisper emits words with start and end times. This is the key trick: knowing when each word happens means a bleep can be aligned to the suspected swear word without manual timeline scrubbing.
Step 3 — Pattern matching
We layer four matching modes on the transcript: exact (match the word verbatim), partial (match any word containing the substring), fuzzy (match minor spelling variations and slang), and manual (click-to-toggle anything else). Built-in profanity lists ship with the tool; you can add custom word lists and review every match.
Step 4 — Audio replacement
Each flagged word gets replaced by a bleep sound aligned to its timestamps. Audio is re-encoded with the bleeps stitched in. Video files get the same treatment on the audio track, while the video itself remains untouched.
FILTER YOUR FILE IN 4 STEPS
UPLOAD AUDIO OR VIDEO
Any MP3, WAV, MP4, MOV, AVI, or WebM file. Browser mode keeps your file on-device; Studio cloud is available for longer recordings.
WHISPER TRANSCRIBES IT
OpenAI's Whisper speech recognition model generates a transcript with word-level timestamps so you can review each match before censoring.
PROFANITY DETECTED AUTOMATICALLY
Built-in profanity lists, fuzzy matching, and custom word lists flag likely problem words. Adjust matches before export — you stay in control.

Pick a bleep sound or silence, preview the result, then download. No watermark.
WHO USES AN AI PROFANITY FILTER?
YouTube Creators
Run videos through the filter before upload to prepare a cleaner, more ad-friendly version.
Teachers & Educators
Filter swear words from documentaries, interviews, and YouTube clips for classroom use. FERPA-safe browser mode.
Podcasters
Create clean episode feeds from raw recordings. No re-recording required.
Legal & Compliance
Beyond profanity — filter names, PII, or any specific words from depositions, training, and recorded calls.
PRIVATE AI FILTERING OPTIONS
Browser mode runs transcription and bleep processing on your device via WebAssembly for short desktop files. For phones and longer recordings, Studio cloud processing is available and clearly indicates when upload-based processing is used.
FREQUENTLY ASKED QUESTIONS
What is an AI profanity filter?
An AI profanity filter uses speech recognition to detect spoken swear words in audio or video, then replaces them with a bleep sound or silence. Traditional profanity filters only match text; an AI filter understands actual spoken language with word-level timing.
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?
Whisper AI produces highly accurate transcripts on clear speech. Combined with built-in profanity lists and pattern matching (exact, partial, fuzzy), it catches most spoken profanity automatically. You can manually adjust the transcript to fix any misses.
Does the AI profanity filter work in real-time?
No — this tool processes uploaded files, not live streams. A 5-minute video typically takes 2-3 minutes to transcribe and filter. For pre-recorded content (podcasts, YouTube uploads, classroom videos), batch processing is faster than real-time filtering anyway.
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, your file stays on your device while transcription and bleep processing run locally via WebAssembly. There's an optional cloud tier for longer files, which clearly indicates when upload-based processing is used.
Files up to 10 minutes processed free. Premium plans for longer recordings.
