About LuxMT

A part of the LuxASR project, LuxMT is a machine translation service specifically designed for Luxembourgish. It uses advanced language models running locally at the University of Luxembourg to provide high-quality translations between Luxembourgish and several other languages including English, French, and German.

Features

Multiple Languages: Translate between Luxembourgish, English, French, German, Spanish, and Portuguese
Auto Language Detection: Automatically detect the source language of your text. Note: Luxembourgish may be detected as German due to linguistic similarity - select "Luxembourgish" manually for best results.
Synchronized Scrolling: Compare source and translation texts easily with automatic scroll synchronization
File Upload: Upload text files (.txt) for translation instead of copy-pasting
Download Translations: Save your translations as text files
Privacy-Focused: All translations are processed locally on university servers - no data is sent to third parties
Fast Processing: Translations typically complete within seconds
Character Limit: Up to 5,000 characters per translation

How to Use

Select your source language (or choose "Auto Detect" to automatically detect the language)
Select your target language (the language you want to translate to)
Enter text manually, paste it, or upload a text file (.txt)
Click the "Translate" button
Your translation will appear in the right panel
Scroll either text window to compare - the other will scroll automatically
Use the copy button to copy to clipboard or download button to save as a file

Tips:

You can swap the source and target languages by clicking the swap button (not available with auto-detect)
Press Ctrl+Enter (or Cmd+Enter on Mac) to quickly translate
Upload text files up to 5MB in size
Auto-detect works best with longer text passages (50+ characters)
Scroll synchronization works automatically - just scroll either window to compare texts

API Access

For programmatic access to the translation service, use the following endpoint:

curl -X POST "https://luxasr.uni.lu/staging/luxmt/translate" \
  -H "Content-Type: application/json" \
  -d '{
    "text": "Your text here",
    "source_lang": "lb",
    "target_lang": "en"
  }'

Disclaimer

All translations are processed on servers at the University of Luxembourg. No data is stored permanently or shared with third parties. The translation quality may vary depending on the text complexity and language pair. For critical translations, we recommend consulting a professional translator.
