  Subtitle Auto-Translator for YouTube — the fastest way to bulk auto-translate your YouTube subtitles to 230+ languages.
  
  Tired of clicking each language one by one? This Chrome extension automates YouTube Studio's auto-translate feature so you can publish subtitles in every language Google supports — all in under a minute per video.
  
  🌐 230+ LANGUAGES: full coverage of YouTube Studio's translation dropdown — Spanish, Portuguese (Brazil), Hindi, Arabic, Russian, Japanese, French, German, Italian, Chinese (Simplified/Traditional), Korean, Turkish, Polish, Vietnamese, Thai, Indonesian, and 200+ more.
  
  ⚡ FAST: ~0.4 second per language via direct API mode. 100 langs done in ~40 seconds. Compare to manual clicking: 5-10 minutes per language.
  
  🎬 MULTI-VIDEO BULK MODE: select multiple videos from your channel — extension processes each one sequentially, end-to-end. Translate your whole channel overnight.
  
  ✨ KEY FEATURES:
  • Bulk auto-translate YouTube subtitles in 1 click
  • Multi-video queue (channel-wide automation)
  • Custom language presets — save your top set
  • Built-in presets: Top 20, Europe, Asia, sample creator-curated 86-language set
  • Auto-skip already-translated languages
  • Auto-skip languages without auto-translate support
  • Real-time progress bar with ETA
  • Compact mode — keeps main video editing space clear
  • Resume after page reload (state persisted locally)
  • Source-language variant filter (e.g., German source skips German variants)
  
  🔒 PRIVACY-FIRST:
  • Runs entirely in YOUR browser
  • Uses YOUR existing YouTube Studio session
  • No third-party servers
  • No tracking / analytics / data collection
  • Storage: chrome.storage.local only (presets, settings)
  
  🎯 PERFECT FOR:
  • Multi-language YouTube creators
  • Channel managers who handle translation backlogs
  • Vegan, cooking, tutorial, educational channels reaching global audiences
  • Anyone tired of manually clicking translate 100+ times
  
  ⚠ REQUIRES: YouTube Studio access (same account that owns the videos). Source captions must be published first.
  
  🆓 100% FREE. No subscription, no signup, no ads.

  🎬 MULTI-VIDEO BULK MODE: select multiple videos from your channel — long-form videos AND Shorts — and the extension processes each one sequentially, end-to-end. Translate your whole channel overnight.
  
  🩳 WORKS WITH SHORTS: not just long videos — translate the subtitles on your Shorts too.
  
  🆕 RECENTLY IMPROVED:
  • Multi-channel: works across every channel on your Google account, including brand / secondary channels (no manual account juggling)
  • Any interface language: works no matter what language YouTube Studio is displayed in (English, Spanish, Russian, Portuguese, …) — not English-only anymore
  • Shorts-only channels supported (Shorts now show in the video list)
  • Safety guard: never publishes empty subtitle tracks — if the source has no text, it stops and tells you instead of creating blank translations
  
  ✨ KEY FEATURES:
  • Bulk auto-translate YouTube subtitles in 1 click
  • Multi-video queue (channel-wide automation, videos + Shorts)
  • Works across multiple channels on one account
  • Works in any YouTube Studio UI language
  • Custom language presets — save your top set
  • Built-in presets: Top 20, Europe, Asia, sample creator-curated 86-language set
  • Auto-skip already-translated languages
  • Auto-skip languages without auto-translate support
  • Never publishes empty tracks (empty-source detection)
  • Real-time progress bar with ETA
  • Compact mode — keeps main video editing space clear
  • Resume after page reload (state persisted locally)
  • Source-language variant filter (e.g., German source skips German variants)

  • Creators running several channels on one account
  • Channel managers who handle translation backlogs
  • Vegan, cooking, tutorial, educational channels reaching global audiences
  • Anyone tired of manually clicking translate 100+ times
  
  ⚠ REQUIRES: YouTube Studio access (an account that owns the videos). The source captions must be published first — this applies to Shorts too (a video with no captions has nothing to translate).
