Bleepster — AI Profanity Filter for YouTube

AI profanity filter for YouTube that automatically mutes swear words across languages for cleaner, family-friendly viewing.

Bleepster helps families enjoy YouTube without unwanted strong language. This AI-powered Chrome extension analyzes available captions and automatically mutes profanity at the moment it is spoken—without blocking the entire video. Unlike basic word-list filters, Bleepster reviews context. It can recognize slang, transliteration, code-switching, disguised or partially censored spellings, and profanity across multiple languages. Word-level caption timing keeps every mute as short and precise as the source allows.
