CopyTranslator addresses the common issue of garbled text translations from sources like PDFs by automatically cleaning and translating copied content. It offers researchers and users a streamlined workflow for foreign language text, enhancing accuracy and efficiency. The latest version integrates advanced Large Language Model (LLM) AI translation services alongside a built-in free engine.

How It Works

The application monitors the system clipboard, preprocesses copied text to correct formatting issues (e.g., PDF line breaks), and then translates it. Version 12 enhances this by supporting various LLM providers via the OpenAI API format (e.g., DeepSeek, Moonshot, Ollama), alongside a free StepFun engine, offering flexibility and improved translation quality.

Quick Start & Requirements

Installation guides are available via provided links. Core functionality does not mandate specific hardware like GPUs, though LLM integration may benefit. The project supports multiple languages and offers integration with OpenAI-compatible APIs. Links to the User Manual, Documentation, and GitHub/Gitee project pages are provided.

Highlighted Details

• LLM Integration: Supports OpenAI API format for advanced translation services (DeepSeek, Moonshot, Zhipu AI, Ollama, etc.).
• PDF Text Cleaning: Optimized to resolve line break and sentence-ending issues common in PDF copy-pasting.
• Dual Translation Modes: Offers "Focus Mode" (translation only) and "Contrast Mode" (original text alongside translation).
• Smart Translation: Intelligently detects and translates between set source and target languages.
• Customization: Extensive options for interface styling, hotkeys, and automated behaviors.
