What LangSwap is
LangSwap is a web service for translating videos into another language while retaining the original voice. Its workflow has users dub a video in their own language, upload it, choose a target language, then download and share the result. The site says the process preserves the original voice and intonation, and describes keeping voiceovers consistent in style and voice across videos. It also lists lip synchronization and voice cloning. The homepage claims video translation can take 15 minutes, even for someone who does not know the target language. LangSwap identifies people handling large volumes of video translation and dubbing as potential users, and presents the service as a way for businesses to reach other language markets. It is described as open source, and web is its listed platform. The homepage invites visitors to try the service for free and request early access through email forms labeled “Get early access” and “Continue,” but lists no plan prices or terms. The footer identifies Peace Data Inc. and displays a 2025 copyright notice. A contact email is [email protected].
