## What it is
CopyTranslator is a cross-platform desktop application that automatically translates text copied to the clipboard, designed as a foreign-language reading and translation assistant. It fixes broken line breaks and sentence splits from copied text and, since v12, supports LLM-based translation via OpenAI-compatible APIs (OpenAI, DeepSeek, Ollama, StepFun, and others).

## Use cases
- translate text just by copying it to the clipboard
- read foreign-language academic papers with instant translation
- fix extra line breaks and broken sentences before translating
- translate using LLMs like OpenAI, DeepSeek, or Ollama
- drag-select text to copy and translate it
- get a free built-in translation engine that works out of the box

## When to choose
- you frequently read foreign-language documents or papers and want instant clipboard-based translation
- you want a free, open-source desktop translator on Windows, macOS, or Linux
- you need to clean up messy copied text (line breaks, hyphenation) before translating
- you want to plug in your own OpenAI-compatible LLM translation provider

## When to avoid
- you need a browser extension or in-page translation rather than clipboard-based workflow
- you need professional or certified translation quality
- you only want a lightweight CLI or API-based translation tool
- you need offline translation without any LLM or online service
