npx myelino --translate

Features

🔒 Local First & Private
Translation calls happen on your machine. We never send your data to third-party APIs or external databases.
🌍 Open Source
Every line of code is transparent and available on GitHub.
🆓 Free Forever
No hidden costs. Now and always.
🤖 Multi-Model Support
Choose from openai, deepseek, moonshot, qwen, or bring your own model.
📚 First-Class i18n Library Support
Works seamlessly with next-intl, react-intl, react-i18next, and more.
🗂 Namespace Support
Supports both namespaced and non-namespaced structures out of the box.

Quick Start

Install Myelin
Ensure Node.js (v18+) is installed, then run:
```
npx myelino --init
```

Configure
Create myelin.config.json in your project root:

{
  "aiProvider": "deepseek",
  "aiModel": "deepseek-chat",
  "locale": {
    "location": "locales",
    "sourceLanguage": "en",
    "targetLanguages": ["es", "fr", "zh", "zh-TW", "en-US"]
  }
}

Add API Key
Create a .env file with your AI provider key:
```
AI_API_KEY=sk-proj-your-api-key
```
Translate!
Run the translation command:
```
npx myelino --translate
```
Myelin scans your source locale file (e.g., locales/en.json), translates new/missing strings, and updates target files (e.g., locales/fr.json).
