Description
Translate text between 100+ languages at runtime, fully offline — no API keys, no internet required after setup.
Auvyra Translate Runtime brings neural machine translation directly into Unreal Engine. Translate UI text, dialogue, player chat, or any dynamic content on the fly, all processed locally on the player's machine. No cloud calls, no recurring costs, no data sent anywhere.
Powered by two AI engines: M2M100 (CTranslate2) for fast, lightweight translation across 100+ languages, and Qwen3-4B (Llama.cpp) for LLM-quality, context-aware translations for natural results.
Perfect for offline games, privacy-focused applications, and real-time multilingual experiences.
