What is LocalePack?

LocalePack is an AI translation tool designed specifically for developers working with internationalisation (i18n) in web applications. You upload your locale files in formats like messages.json and select which of the 52 supported languages you need translations for. The tool handles the translation using AI whilst preserving your placeholder variables and nested file structures, then outputs ready-to-use locale files in the correct format for your framework. It supports common i18n libraries including Next.js, vue-i18n, and i18next, as well as browser extension localisation. The service operates on a one-time payment model rather than a subscription, making it straightforward for teams that need periodic translation work without ongoing costs.

Pros & cons

Advantages

  • Straightforward workflow; upload your file and download translations without configuration overhead
  • Respects code-safe elements like placeholders and nested structures, reducing manual fixes after translation
  • Cost-effective for occasional translation needs since you pay once rather than per translation or monthly
  • Covers many languages (52) suitable for global applications

Limitations

  • Quality of translations depends on AI model; you may need to review and edit output for nuance or context-specific accuracy
  • Limited to text-based file formats; complex localisation scenarios (plurals, gender-based variants) may need manual handling
  • No built-in collaboration features for teams to review translations before deploying

Use cases
