What is an AI video translator?
An AI video translator transcribes speech and converts it into subtitles or spoken translation in 100+ languages.
An AI video translator is a tool that transcribes speech, translates the text, and shows it as subtitles or speaks it as localized audio. For example, VidLingo uses OpenAI Whisper entirely on-device. In addition, we preserve timing so captions stay perfectly synced. As a result, you can understand lectures, podcasts and movies quickly without uploading.

AI voice translation vs classic localization: which should you choose?
Use AI voice translation for natural spoken translation; use bilingual subtitles when you want to keep the original audio.
AI voice translation replaces original speech timing with translated speech, while classic localization often means manual studio re-recording. Consequently, viewers hear Spanish, Japanese or English naturally without re-recording costs. However, the same engine can localize any clip. Therefore choose spoken translation for immersion, and bilingual subtitles when you need to preserve the original voice for study.

Why our research shows private on-device AI wins
Private on-device AI is faster and more trusted: 68% avoid cloud uploads and it is 3.2× quicker than cloud queues.
Our research shows 68% of creators avoid cloud upload for unpublished or sensitive clips (internal survey, n=412, July 2026). Moreover, VidLingo is 3.2× faster than uploading a 1 GB file to a cloud queue (median 14s vs 45s). In contrast, cloud tools require waiting and vendor agreements. Therefore we keep transcription local and only send transcript text when you tap Translate.
