AI Localization Automator Documentation

AI Localization Automator is a powerful Unreal Engine plugin that streamlines game localization using AI-powered translation services. It integrates seamlessly with UE's built-in Localization Dashboard and supports multiple AI providers including OpenAI, Anthropic Claude, DeepSeek, Google Gemini, and Ollama for local AI translation.

The translated content works with all Unreal Engine target platforms - the resulting localization files are universal and work wherever you deploy your UE project.

Key Features​

  • Multiple AI Providers: Choose from OpenAI, Claude, DeepSeek, Gemini, or run locally with Ollama
  • Seamless Integration: Built-in integration with Unreal Engine's Localization Dashboard
  • Batch Processing: Translate hundreds of text entries efficiently with configurable concurrency
  • Smart Retry System: Automatic retry logic with configurable failure thresholds
  • Real-time Progress Tracking: Live progress updates with detailed status information
  • Context-aware Translation: Uses culture-specific language names and customizable prompts
  • Preset System: Save and load complete configuration presets for different projects
  • Session Management: Track which translations were made in the current session
  • Robust Error Handling: Comprehensive error reporting and recovery mechanisms
  • Production Ready: Tested extensively with large-scale localization projects

How It Works​

The plugin automatically discovers all localizable text in your project through UE's localization system, then uses your chosen AI provider to translate content into your target languages. The translation process is:

  1. Automatic Discovery: Finds all gathered text entries from your localization target
  2. Smart Batching: Processes translations with configurable concurrent requests
  3. AI Translation: Sends context-aware prompts to your chosen AI provider
  4. Quality Control: Preserves format specifiers, placeholders, and special markup
  5. Integration: Saves results directly to UE's localization archive files
  6. Progress Tracking: Provides real-time feedback on translation progress
