Three steps between a swear and your speakers.
No dictionaries. No word lists. Just YouTube's own captions and context-aware AI — already included.
- 01
It reads the captions
Bleepster captures YouTube's own subtitle track with word-level timing, straight from the player. The audio itself never leaves the tab.
- 02
AI reads between the lines
Bleepster AI reviews the transcript in context — slang, transliteration, disguised spellings, mixed languages. The AI decides, not a word list.
- 03
The word disappears
Muting is scheduled on the audio clock with sample accuracy. Just the word — not the sentence. A clean silence or a classic bleep, your call.

A YouTube profanity filter built to bleep one word.
Muting a single word in a live video, in any language, is harder than it sounds. Bleepster sweats the details so you don't have to.
Any language. Really.
There’s no built-in dictionary to outgrow. The AI reads captions in context — slang, transliteration, disguised spellings, even mid-sentence language switching. If YouTube can caption it, Bleepster can bleep it.
Explore language support →Surgical timing
Word-level timestamps from the player, with mutes scheduled on the Web Audio clock for precise playback timing. The word disappears. The sentence survives.
Block videos and channels
When a bleep isn’t enough, stop the video. Turn on blocking for videos with profanity, or keep your own list of channels and videos that should never play. The Parent PIN keeps both in place.

Parent PIN
A 4-digit lock keeps kids out of the settings. Stored as a salted hash on your device — never synced anywhere.
Safe start
Optional. New videos pause for about three seconds while the opening is checked, so early words are less likely to slip through. Always skippable.
AI included
No provider account, API key, or technical setup. Sign in, open a captioned YouTube video, and Bleepster handles the analysis.
Set how strict
Relaxed, Balanced, or Strict filter strength, with a classic censor bleep or a clean mute. Whatever fits your living room.
Rewatch free forever
Every analyzed video is cached on your device. Rewatches don't touch your free-video count or trigger another analysis.
No fake safety
If a video can't be filtered — no captions, limit reached — Bleepster says so right on the toolbar icon. It never pretends you're protected.
For parents who can’t preview every video.
Gaming videos, reaction channels, vlogs — a kid’s YouTube diet is full of casual profanity that age ratings never catch. You can’t pre-watch it all. You shouldn’t have to.
You decide what plays
Mute only the swearing and let them keep their channels, or block a channel, a video, or any video with profanity.
You keep control
The Parent PIN puts the on/off switch and every setting behind four digits only you know.
No silent failures
The moment a video can't be filtered, the toolbar icon shows an orange badge and the popup says so — in plain words, not fine print.
By default, Bleepster mutes profanity and obscenity while ordinary insults and mild language stay. Strict filter strength also mutes mild curses and insults.
Your audio never leaves the tab.
Read the privacy policy- Audio is never downloaded or uploaded — analysis works on caption text only.
- Caption text is securely sent through Bleepster to OpenRouter for analysis.

Questions, answered.
Where can I install it?
Bleepster is available on the Chrome Web Store, Microsoft Edge Add-ons, Firefox Add-ons, and as a Safari download for Mac from this website. Install it, sign in with your email, and open a captioned YouTube video. AI analysis is included. Use the arrow next to the install button to pick another browser.
Which languages can it filter?
Any language YouTube can caption. There's no fixed dictionary — the AI reads captions in context, including slang, transliteration, and disguised spellings. Accuracy is strongest on widely spoken languages; English and German are tested most heavily.
Is Bleepster itself available in my language?
The interface is available in English, German, French, Portuguese, Spanish, Dutch, Italian, Japanese, Korean, and Chinese. It follows your browser language, or you can pick another one in Settings.
Can I block videos or channels?
Yes, on Free and Premium. Turn on Block videos with profanity to stop a video as soon as its captions show profanity at your filter strength, or add channels and videos to your own block list with a link, an @handle, or a button in the popup. A blocked video counts as one of the 10 Free videos. The profanity check needs captions, and blocking doesn't hide videos from YouTube feeds.
Do I need an AI API key?
No. AI analysis is built into Bleepster. There is no provider account, API key, model choice, or separate AI bill to configure.
What are the Premium plans?
Choose $4.99 per month or $19.99 for lifetime access with a one-time payment. Both include AI analysis and unlimited analyzed videos for one household on up to 3 devices or browser profiles. Choose Monthly or Lifetime in the extension before continuing to Stripe Checkout.
Does Premium renew automatically?
Monthly Premium renews until canceled. You can manage or cancel it in the Stripe customer portal from Bleepster Settings; cancellation takes effect at the end of the paid billing period. Lifetime is a one-time payment with no subscription or recurring charge.
Does Bleepster listen to or upload my audio?
No. Audio is never downloaded or uploaded. Bleepster works from YouTube's caption text, which is securely sent through the Bleepster service to OpenRouter for analysis. Muting happens locally in the tab.
What if a video has no captions?
No captions means no text to analyze, so that video can't be filtered. Bleepster tells you clearly — an orange badge on the icon and a plain-words status in the popup — instead of pretending you're covered.
Can my kid just turn it off?
The Parent PIN locks the popup — the on/off switch and every setting sits behind four digits only you know. Removing the extension itself is a browser-level action; for a truly locked-down setup, a managed force-install policy in Chrome, Edge, or Firefox closes that door too.
What exactly gets muted?
Profanity and obscenity — the words a broadcaster would bleep. At the default Balanced strength, ordinary insults and mild language stay. Relaxed mutes only the harshest words, and Strict also mutes mild curses and insults. Non-speech captions like [music] or [laughter] are never touched.
Does the free plan expire?
No. Free gives you 10 analyzed videos with every feature included, tied to your account rather than your device — reinstalling doesn't reset it, and already-analyzed videos keep filtering forever.
The internet swears. Your speakers don’t have to.
