Echoly — Ai Voice Dubbing

Echoly turns any video on the web into a video in your language. Press Start and hear natural AI voice dubbing on top of the original — voice-to-voice, on any site with a video player: YouTube, Coursera, Udemy, and more.

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.

WHAT IT'S GREAT FOR

• Following courses and tutorials published in other languages.
• Long-form interviews, podcasts, and product launches without waiting for official subtitles.
• Practicing a new language by listening to native content with a parallel dub.
