About Translate GPT
Translate GPT is an open-source fastlane plugin that integrates OpenAI's GPT API to automate the translation of localizable strings for iOS and Android applications. Designed for developers using fastlane, it streamlines the localization workflow by detecting the source language, translating strings into a specified target language, and optionally using contextual comments to improve translation accuracy. The plugin can skip already-translated strings to reduce API costs and improve performance. It is hosted on GitHub under the MIT license and is intended for use within a fastlane CI/CD pipeline.

Pros & Cons
Pros
- Open-source and free to use (no additional licensing costs beyond OpenAI API usage)
- Automates a tedious localization process, saving developer time
- Leverages powerful GPT models for high-quality translations
- Context-aware translation can improve accuracy compared to basic machine translation
- Seamlessly integrates with existing fastlane workflows
Cons
- Requires an OpenAI API key and incurs API usage costs
- Dependent on fastlane; not a standalone tool
- Translation quality depends on the chosen GPT model and prompt configuration
- Limited to string file formats supported by fastlane (e.g., .strings, .xml)
- No built-in support for non-string content like images or audio
