YuLaF – YouTube Language Filter sɣur Emrah

YuLaF cleans up your YouTube feed by hiding videos that aren't in the languages you actually care about. Pick one or more target languages and only matching videos stay visible — across the home feed, search results, channel pages, and recommendations.

Built for:
- Language learners who want maximum exposure to their target language
- Polyglots tired of mixed-language recommendations
- Anyone who wants a quieter, more focused YouTube

How it works:
- Detects each video's language from its title and description using Chrome's built-in i18n API plus character-script
validation (Hiragana, Hangul, Cyrillic, Arabic, Devanagari, and more)
- Hides non-matching videos in real time, no page refresh needed
- Tracks videos filtered, time reclaimed, and your daily streak — all stored locally

Privacy-first:
- Zero data collection, zero telemetry, zero remote servers
- All language detection runs on your device
- Settings sync via your browser's built-in storage, never a third party

Features:
- 61 supported languages
- Multi-language selection (e.g. learn Japanese AND keep English)
- Strict mode for higher detection confidence
- Customizable keyboard shortcut (default Alt+Y / Ctrl+Y)
- Filter activity stats: videos filtered, time reclaimed, active streak
- Works on YouTube home, search, recommendations, and channel pages
