Bleepster — AI Profanity Filter for YouTube

Automatically mute swear words on YouTube with context-aware AI for cleaner, family-friendly viewing across languages.

Bleep the words. Keep the fun. Bleepster automatically mutes profanity in YouTube videos, so families can watch together without reaching for the volume controls. It uses available captions and context-aware AI to identify strong language, then silences it at the moment it is spoken. The video keeps playing. MADE FOR FAMILY VIEWING Keep the creators, stories, and laughs your family enjoys—with less unwanted language. Choose a classic bleep sound or silent muting, and protect the extension settings with a private 4-digit Parent PIN. SMARTER THAN A WORD LIST Bleepster reviews words in context. It can recognize slang, transliteration, code-switching, disguised or partially censored spellings, and profanity across multiple languages. Precise caption timing keeps each mute as short as the source allows.
