What LangSwap is

LangSwap is a web service for translating and dubbing videos into another language while retaining the original voice. Its workflow starts with dubbing a video in your own language, then uploading it and choosing a target language; you can download and share the translated result. LangSwap is designed to preserve the original voice and intonation during translation, and it can keep a voiceover consistent in style and voice across videos. It also offers lip synchronization and voice cloning. The service claims video translation can take 15 minutes, including for users who do not know the target language. LangSwap is aimed at people who need to translate and dub videos in large volumes, and it is presented as a way for businesses to reach other language markets. The service is open source and runs on the web. Its homepage invites visitors to try it for free and request early access through email forms labeled “Get early access” and “Continue.” The footer identifies Peace Data Inc. and displays a 2025 copyright notice.
