What STranslate is
STranslate is an online tool developed by ZGGSONG that integrates translation and OCR functions. For translation, it supports several input methods including typing text, selecting words, and taking screenshots, and it can display results from multiple translation services at the same time so you can compare them. For OCR, it handles Chinese, English, Japanese, and Korean using PaddleOCR technology, works from screenshots, the clipboard, and files, and includes a silent OCR mode. The tool integrates with more than ten translation services, including OpenAI, Gemini, ChatGLM, Baidu, and Microsoft, and it provides a free API option.

- Compare translations from several services in one view.
- Run OCR on screenshots, clipboard images, or files in four languages.
- Use silent OCR for quick recognition without extra dialogs.
- Connect your own translation service keys, or use the API in your own projects.
- Use extra features such as back-translation, global text to speech, and writing assistance.
Who it is for
- Anyone who translates text frequently and wants results from several engines at once.
- Users who need to turn printed or scanned text into editable digital text.
- Developers who want to add translation or OCR to an application through the API.
- People who work with Chinese, English, Japanese, or Korean documents.
What to watch out for
Translation quality depends on the service and the language pair, so machine output still needs human review for important documents. Some translation services require your own API key, and the free API option may have limits that can change. Offline OCR supports a fixed set of four languages, and recognition accuracy drops on blurry or low-contrast images. Check current terms before relying on the service for paid work, and test the OCR on your own file types before building a workflow around it.
