What is Lookupper?

Lookupper is a modern, high-performance screen translator designed specifically for gamers and language learners. Unlike traditional screen translators that rely on slow, outdated frameworks, Lookupper is built with WinUI 3 and NativeAOT, ensuring zero impact on gaming performance (FPS).

It acts as a smart overlay that can "see" text in any application—be it a video game, visual novel, manga, or a PDF document, and provide instant, context-aware translations using advanced AI models.

Key Features:

  • Gaming-First Design: Works flawlessly over full-screen games without minimizing the window.
  • AI Context Awareness: Uses Large Language Models (LLM) to understand game slang, lore, and dialogue context, avoiding the "robotic" feel of standard translators.
  • Powered by a custom-built OCR engine engineered to surpass Google Lens and DeepL in both performance and precision.
  • Language Learning Tools: Save words to your personal dictionary, export to Anki, and view grammatical explanations for complex sentences.screen-translator, game-translator, visual-novel-translator, ocr, language-learning, ai-translation, winui-3, windows-11, overlay, japanese-learning, immersio
  • Native Performance.

Lookupper is the perfect modern alternative to tools like Textractor, Translumo, LunaTranslator, DeepL, QTranslate, or ShareX for users who need real-time, high-quality translation without breaking their immersion.
