Voxylio — multilingual dubbing by LN

Voxylio makes your videos speak your language.

It reads the video's subtitles — the player's track, or the captions shown on screen on YouTube, Netflix, Prime Video, Disney+ and Twitch — rebuilds complete sentences, translates them, then speaks over the video with a synchronized voice while the original audio gently ducks under it.

★ Full-sentence dubbing — a fluid voice, translations in context
★ 70+ target languages — source language detected automatically
★ Free on the big platforms (YouTube, Netflix, Prime Video, Disney+, Twitch): unlimited on-device translation (Chrome's built-in API) + your system voices — no card
★ A free Voxylio account (Google sign-in) is required — every new account starts with a 3-day trial that unlocks every site
★ Optional Pro: contextual AI translation (beta) — whole scenes translated coherently — and natural neural voices in 7 languages, with automatic local fallback
★ Pro no-subtitle dubbing (beta): when a video has no captions at all, its audio is transcribed live and dubbed — 60 min of Premium Audio per month
★ Personal glossary: force your translations, protect your terms
★ Bilingual on-screen captions (original + translation)
★ Launch button — starts without reloading the page, and switches the player's captions on for you when possible
★ Floating controller: language, voice, speed, original-audio mix
★ Dubbing history and statistics computed locally, transcript export (.srt)

The engine works wherever subtitles exist — course platforms, video documentation, standard HTML5 players. The free plan covers the big platforms above; the 3-day trial and Pro unlock every other site.
