AI Video Translator & Dubbing
ViralMint is a free AI video translator and automated dubbing tool that converts your speech into 21 languages while preserving timing and word-by-word captions.
Why ViralMint for this
Timed-Sync Technology
Our dubbing engine uses Whisper's word-level timestamps to ensure the translated audio matches the original speaker's pacing. The tool automatically adjusts audio speed to stay in sync with the visual scene changes.
Word-by-Word Translated Captions
Get more than just audio. ViralMint generates translated captions in the viral word-by-word style, helping viewers follow along even in loud environments. No manual subtitle editing required.

Frequently asked
Which languages are currently supported for dubbing?
ViralMint currently supports 21 languages including English, Spanish, Portuguese, German, French, Mandarin, Japanese, Korean, Hindi, and Arabic. We are adding more voices regularly via our OpenRouter integration.
Does ViralMint support voice cloning?
Yes. ViralMint clones a voice from a short reference clip and narrates your videos in it, and it runs 100% on your own machine (the VoxCPM engine) — your reference audio never leaves your device. That on-device design sidesteps the privacy and consent concerns of cloud cloning services. It's an optional one-time install on macOS and Linux, priced at a few cents per generation (capped at 20¢). Prefer not to clone a voice? The 13 Gemini neural voices and 400+ free Edge TTS voices are still there.
