About

VeluTranslate is a cloud-based localization management platform for game, app, and website teams. Its web dashboard organizes projects, translation keys, languages, and localized content, with tools for collaboration, import, review, editing, and export. Teams can publish language files to a CDN so connected games and applications can retrieve text updates without rebuilding or releasing a new version. An official Unreal Engine plugin supports runtime language loading and switching; Unity, Godot, web apps, and custom clients can connect through a read-only Runtime JSON API. The platform also offers language-demand signals, detection of requests for unsupported languages, optional AI-assisted translation using separate credits, and an HTML editor with rendered preview. It supports localization workflows for live games, mobile and web applications, and other digital projects.
