TrueTone — Mute Profanity on YouTube

Automatically mutes profanity, slurs, and other configurable categories on YouTube using caption timestamps.

Let your kids keep watching regular YouTube without you needing to babysit the remote. TrueTone is a Manifest V3 Chrome extension that automatically mutes profanity, slurs, and other configurable categories of language on YouTube videos in real time, using YouTube's own caption data rather than clunky audio analysis. Unlike YouTube Restricted Mode, which hides entire videos, TrueTone keeps the video playing smoothly and only mutes the audio for a split second the exact moment a flagged word is spoken. There is no re-buffering, re-encoding, or added delay. It works automatically on every video and every channel with no manual timestamps, editing, or re-watching required. Key Features & Customization • Six Filterable Categories: Choose which categories to mute by toggling any combination on or off. Profanity (general swearing) and Slurs (racial and ethnic terms) are on by default. Sexual (explicit language), Blasphemy (religious profanity), Violence (graphic descriptions), and Drugs (illicit drug references) are off by default. • Full Word Control: You are not limited to simple toggles. You can view, add, or remove the exact words and phrases each category blocks. • Unlimited Custom Words: Add your own custom words and phrases on top of the pre-set categories to fit your family's standards. • Unlimited Local Profiles: Set up multiple local profiles on a single device—such as separate filtering setups for different children, each with their own unique category and word settings. How It Works Install the extension from the Chrome Web Store. Purchase a plan and activate it using a 6-digit code from your online dashboard to unlock local filtering features. Choose your preferred categories and custom words in the settings. Filtering starts instantly. TrueTone reads captions the moment a video plays and mutes the audio for a split second the instant a flagged word is spoken. Privacy and Local Operation Your family's viewing habits remain completely private. Filtering runs one hundred percent locally in your browser. Nothing you watch, no caption data, no viewing history, and no personal data are ever sent to a server. The extension only communicates with TrueTone servers for two narrow functions: initial license activation and periodic license-status checks. It never touches YouTube's or any third-party servers beyond reading the public caption data already loaded by YouTube itself. Once your license is activated, filtering continues to work fully offline and indefinitely with no ongoing internet connection required. Coverage and Honest Limits TrueTone works on any YouTube video that has captions available, which covers the vast majority of YouTube. Please note that videos with no captions at all cannot be filtered yet. This is a genuine current limitation rather than a bug, and accuracy depends entirely on the availability of accurate caption data. Every purchase is backed by a money-back guarantee: if TrueTone fails to successfully filter profanity on YouTube during normal supported use, your purchase is refunded.
