LocaFile AI
LocaFile AI is a paid, web-based localization service designed to translate app, website, game, and subtitle files into 28 languages while preserving code variables and placeholders. It accepts common formats such as Android strings.xml, iOS .strings, JSON/YAML for websites, SRT/VTT/ASS subtitles, Godot, Unity, Laravel, and i18next files. The service is aimed at indie game developers and small teams who need fast, production-ready translations without the cost of traditional localization agencies. The core of LocaFile AI is a multi-stage pipeline. First, a heavyweight AI model translates the text, capturing cultural context and natural language. Second, a cross-model native editing pass refines phrasing and cadence. Finally, deterministic verification checks that all variables, placeholders, and file structures remain intact. The platform includes a VariableLocker that replaces placeholders like {player_name}, %s, Smart Strings, and HTML tags with opaque tokens before translation, then restores them after, preventing broken code and JSON. LocaFile AI is available from $39 per project, with a free preview of the first five strings and no login required. The service is Stripe-secured and delivers a ZIP file via email. It was built by the developers of FastOG, BeCaSimulations, and Truck Empire, and is used on their own projects. The tool explicitly does not handle UI layout, font sizing, cultural LQA, voice acting, or regional pricing, focusing solely on string translation.

Problem solved
Localization with generic AI tools often breaks placeholders like {player_name} or %s, skips long strings, and produces invalid files, while agencies are expensive and slow. LocaFile AI solves this by locking variables before translation, verifying them after, and translating every string in a file into 28 languages, delivering a production-ready ZIP in minutes.
