SanityTV — Bist0uille

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.
