Echo Captions: Video & Subtitle Translator

Translate YouTube videos, Twitch & Kick live streams and Crunchyroll anime. Auto AI subtitles & live captions in 14 languages.

Echo Captions is a video translation and subtitle translation extension for YouTube, Twitch, Kick and Crunchyroll. No setup after install: open a YouTube video and translated captions appear by themselves. Real-time AI speech recognition listens, translates what is said and renders clean translated subtitles right on top of the video — watch any video or live stream in your own language. Want to watch an English video with subtitles in your language? Need a live interpreter for a Twitch or Kick stream? Following a YouTube video or anime in a language you don't speak? Echo Captions does it by itself. AFTER INSTALLING 1. Add the extension — a short welcome page and demo video let you try it in seconds. 2. Open any YouTube video — translated captions start by themselves. No clicks, no setup. Your language is detected from your browser. 3. The Echo button in the player turns captions on and off anytime. On live streams (YouTube Live, Twitch, Kick) and Crunchyroll, one click on the Echo button starts translation. WHAT YOU CAN DO • Self-starting translation — captions open automatically on YouTube videos; turn them off with one tap if you prefer. • YouTube video translation — automatic translated subtitles, with smart caching so rewatches load instantly. • Live stream caption translation — real-time translated captions for YouTube Live, Twitch and Kick as people speak. • Crunchyroll anime subtitles — official subtitles translated into your language, built-in subtitles hidden. • Dual subtitles (bilingual) — translation and original line together; follow the meaning in your language while seeing what was said. • AI auto captions — no transcript or CC needed; Echo turns speech into captions in real time. • Transcript panel — a scrollable, searchable transcript that follows the video like a prompter. • Language learning mode — vocabulary-focused hints and explanations instead of plain translation. Learn English, Japanese or any language while you watch. • Full subtitle customization — font, size, background opacity and position; separate styles for YouTube, live streams and Crunchyroll. TRANSLATE INTO 14 LANGUAGES English, Turkish, Spanish, French, German, Japanese, Korean, Chinese, Arabic, Russian, Portuguese, Italian, Hindi and Dutch. For example: watch an English video with Spanish subtitles, or Japanese anime with English subtitles. SUPPORTED PLATFORMS • YouTube videos • YouTube Live • Twitch live streams • Kick live streams • Crunchyroll episodes (anime) WHY ECHO CAPTIONS You shouldn't miss what's being said just because it's in another language. No waiting for dubs — Echo transcribes speech instantly and shows it as translated subtitles on screen, like a simultaneous interpreter. No copy-paste, no second window, no transcript needed — most of the time, not even a click. LANGUAGE & MODEL SETTINGS Your target language is detected from your browser; change it anytime from the popup. Toggle auto-translate with one switch, and on supported plans manage the translation model and live caption settings.
