Localization AI for Unity

An AI-powered localization tool for Unity's Localization package, using OpenAI's GPT models to automate string table translations.

Features

• Automated Batch Translation: Translate multiple String Table Collections at once.
• Context-Aware AI: Uses GPT-4o and other models for high-quality, nuanced translations.
• Flexible Configuration: Choose your source and target locales dynamically.
• Customizable Prompts: Override the system prompt to fine-tune the AI's persona and translation rules.
• Translation Preview: Test translations for specific text before running a batch process.
• Existing Translation Management: Choose whether to keep or overwrite existing translations.

Requirements

• Unity 2022.3 or later (Tested on Unity 6)
• Unity Localization Package (com.unity.localization)
• OpenAI API Key

3. Enter the following URL: https://github.com/IJEMIN/Unity-Localization-AI.git

Setup

1. Configure OpenAI API Key

Go to Unity Preferences > Localization AI and enter your OpenAI API Key. You can also select your preferred GPT model (e.g., gpt-4o, gpt-4o-mini).

2. Set Up Locales

Ensure your project has the Unity Localization package configured with at least two Locales (Source and Target).

How to Use

1. Open the Localization AI Window

Navigate to Window > Asset Management > Localization AI.

2. Select Locales and Tables

• Source Locale: The language you are translating from.
• Target Locale: The language you want to translate into.
• Overwrite Existing Translation: Check this if you want the AI to replace strings that already have translations.
• Select Tables: Toggle the checkboxes for the String Table Collections you wish to process.

3. Test Translation (Optional)

Use the Test Translation Preview panel to see how the AI handles a specific piece of text before starting the full process.

4. Start Translation

Click Start Translation Process. A progress bar will appear, and the AI will begin populating your target tables.

Customizing Translation Rules

If you need the AI to follow specific rules (e.g., "Keep technical terms in English", "Use a polite tone"), you can enable Override System Prompt in Preferences > Localization AI.
