Accurate transcription from real audio
Our AI listens to the actual spoken audio in your MP4 or MOV and produces a precise transcript — no manual typing, no guessing. It handles accents, background noise, and multiple speakers so the translation starts from a solid foundation.
Translate into dozens of languages
Translate your video into any of the world's most-spoken languages while preserving meaning, tone, and context. Reach a global audience without hiring a translator or re-recording a single word.
Works with YouTube links too
Paste any public YouTube URL and translate it just like an uploaded file. We read the real spoken audio, so you get an accurate translation and AI dub — perfect for repurposing your own videos for new markets.
Free & no signup required
The AI video translator is 100% free with no account needed at launch. Upload your file or paste a link, choose a language, and download the dubbed result. Nothing to install, nothing to pay for.
