Auto Subtitle Translator & Publisher for YouTube

Automatically translate and register YouTube Studio video subtitles into 15 languages.

Subtitle Auto-Translator is a Chrome extension that automatically translates and uploads YouTube Studio subtitles, titles, and descriptions into multiple languages using Google Gemini AI. Stop repeating the same translation and upload work for every language. With a single click, translate into up to 15 languages at once. 【Key Features】 • 15-language batch translation — English, Japanese, Spanish, and more, all at once • Subtitles + titles + descriptions — video metadata is localized and registered too • No API key required — just sign in with Google and top up credits • No charge on failure — credits are deducted only for what actually succeeds • Skips already-translated languages automatically — avoids unnecessary usage • Real-time progress — see status at a glance, e.g. [French] Translating... (3/8 chunks) • Direct upload to YouTube Studio — results are pushed straight to your subtitle tracks • History & notices — review past results and updates in the sidebar; delete records individually • KakaoPay and PayPal payments supported 【How to Use】 1. Install the extension and sign in with your Google account. 2. Top up credits (KakaoPay or PayPal). 3. Open the "Subtitles" page of the video you want to localize in YouTube Studio. 4. Select target languages in the sidebar and click [Start Translation]. 5. Once complete, subtitles, titles, and descriptions are uploaded automatically. 【Notes】 • Credits are prepaid and deducted based on actual usage. • Works on videos that already have source subtitles. (It does not generate captions from scratch.) • Translation results are AI-generated and may contain errors.
