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 — 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) 🔒 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 (long videos and Shorts) • 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). 🆓 100% FREE. No subscription, no signup, no ads.
