Bleepster

Bleepster mutes profanity in YouTube videos while playback continues. It reads captions and uses context-aware AI to detect swear words, slang, disguised spellings and mixed languages, then filters at word-level timing. Choose silence or a classic censor bleep. A 4-digit Parent PIN locks settings and the on/off switch. Audio stays in your browser tab; only caption text is sent for AI analysis. Local caching keeps rewatches filtered without using another free video. Available for Chrome, Edge, Firefox and Safari on Mac. Videos without captions cannot be filtered, and caption errors can affect accuracy. Bleepster filters profanity and obscenity; it does not block videos, adult themes, violence or comments. The first 10 newly analyzed videos are free. Premium costs $4.99 per month or $19.99 once for lifetime access, covering one household on up to 3 devices or browser profiles.
