String Catalog

String Catalog is an advanced AI-powered localization platform designed to put your app's translation workflow on autopilot. Specifically built for iOS and Android developers, it eliminates the tedious and time-consuming process of manual string management and translation. By seamlessly integrating with GitHub, String Catalog monitors your codebase for changes. Whenever you push new or modified strings, it automatically generates high-quality translations for over 40 languages and opens a pull request, ensuring your localizations are always in sync with your development cycle.

This tool is engineered to feel like a natural extension of the development process, removing the bottleneck that often slows down global releases. It's trusted by hundreds of developers, from indie creators to growing businesses, for its efficiency, accuracy, and affordability. String Catalog allows teams to move faster, launch features globally, and reach millions of new users without the traditional overhead of localization management.

How to use String Catalog

Getting started with String Catalog is a straightforward, three-step process designed for maximum efficiency:

1. Connect Your Repo: Authorize the String Catalog GitHub App and select the repository and branch you want to localize. The platform will automatically scan for your localization files, such as Xcode's .xcstrings or Android's strings.xml. For users who prefer not to use GitHub integration, a manual upload option for these files is also available.
2. Configure & Localize: Choose your target languages from a list of over 40 supported locales. You can fine-tune the AI's output by setting a specific tone of voice or providing custom prompts for better context. Once configured, simply click "Localize," and the AI will process all your strings.
3. Review & Merge: Within minutes, you'll receive a pull request in your GitHub repository containing all the translated strings. You can review the changes directly in GitHub's diff viewer. Once you're satisfied, merge the PR, and your app is instantly updated with the new localizations. The process ensures continuous synchronization with every new push.
