YouTube Subtitle AIとは
AI-powered YouTube subtitle generator with translation and dual-language display AI Subtitles - Subtitles, translation, and chat for any YouTube video.
No captions on the video? No problem. AI Subtitles generates accurate subtitles for any YouTube video using Google's Gemini AI - even videos that have zero captions.
GENERATE SUBTITLES FOR ANY VIDEO One click. Works on lectures, interviews, vlogs, foreign-language content — anything on YouTube. Subtitles display as a clean overlay directly on the video, matched to YouTube's native look.
TRANSLATE TO 50+ LANGUAGES Select a language, hit translate. Original text stays visible above each translation so you can compare - great for language learning or verifying context.
CHAT WITH THE TRANSCRIPT Ask questions about what you just watched. Get summaries, find specific moments, or dig into topics. Responses include clickable timestamps that jump straight to the relevant part of the video.
BUILT TO STAY OUT OF YOUR WAY
