Copy Translator

Copy Translator is a lightweight translation tool written in Rust.

Features

• Extremely lightweight
• Automatically removes extra line breaks and sentence breaks, optimizing PDF translation experience
• Translate on selection (selection-based translation), perfect for reading academic papers
• Uses DeepL for translation, delivering excellent results

How to Use

The tool is a single exe file. Once launched, it runs in the background. Select text and press ctrl+d or ctrl+q to open the translation interface. Press esc to close it, and ctrl+shift+d to fully exit.

When the interface is open, you can trigger translation by selecting text without using a shortcut key — this is the so-called "selection-based translation".
