SanityTV

SanityTV gives you a calmer YouTube by filtering out videos that exploit your attention through clickbait, rage-bait, sensationalism, brainrot patterns, or content harmful to children. WHAT IT DOES SanityTV scores each video on the YouTube home, search, and sidebar using a transparent set of heuristics. By default, any video that crosses the threshold disappears from your feed — you simply see fewer videos. Prefer a softer experience? Turn off "Hide all flagged" in the popup and borderline matches will be greyed-out with a warning badge instead, still clickable. You can also adjust the sensitivity slider, or turn the filter off entirely with one click. WHAT IT DETECTS • Clickbait titles (uppercase shouting, listicles, "you won't believe", emoji spam, repeated punctuation) • Rage-bait (combat verbs like "DESTROYS", culture-war keywords, confrontation framings) • Sensationalism (mystery patterns, conspiracy keywords, hidden- truth narratives, morbid keywords for tabloid-style coverage) • Brainrot signals (Shorts duration, emoji spam) • Harmful kid content (Elsagate-style co-occurrences, named dangerous challenges like Tide Pod or Blackout) It works in English and French out of the box. WHAT IT DOES NOT DO • No data leaves your browser. Ever. • No third-party servers, no telemetry, no analytics. • No API key required. • Does not modify the YouTube video player itself. • Is not a parental control. Use YouTube Kids for that. FOR THE CURIOUS The full source code is on GitHub. Every detection rule is a few dozen lines of TypeScript you can read. The architecture decisions are documented as ADRs in the repo. The extension passes 130 unit tests and 16/18 empirical tests against real YouTube searches before each release. PRIVACY SanityTV does not collect, transmit, or sell any data.
