WHY ECHOLY • Voice-to-voice dubbing — you hear a real voice speaking your language, not robotic text-to-speech over silence. • Works where you already watch. No uploads, no copy-pasting links. Open a video, press Start. • Translated captions on YouTube when available, with adjustable subtitle styling on paid plans. • Keeps up with you: pause and resume follow the video, ads are detected and skipped, and dubbing continues automatically to the next video in a playlist. TWO MODES • Standard (~5s delay) — high-quality dubbing for lectures, podcasts, interviews, and long-form video. • Realtime (<1s delay, Max plan) — near-live translation for livestreams and fast conversation. LANGUAGES & VOICES Dub into English, Spanish, Portuguese, French, German, Italian, Russian, Japanese, Korean, Chinese, Hindi, Indonesian, Vietnamese, and more. Pick the voice you like, set your source language when you want more control, and Echoly handles the rest.
