Translate what you see, where you see it

TranslateWindow is built for the moment when the text you need is already on your screen: a web page, a PDF, a screenshot, a subtitle, or an app interface that cannot be copied cleanly.

Open the realtime window, place the frame over the content, and the translated Chinese patches appear close to the source text. You keep reading in the same place instead of jumping between a document, a browser tab, and a translator.

A small panel for copyable text

For normal text, the floating panel handles the fast paths. Select an English word or phrase to see a Chinese translation with concise bilingual dictionary notes, or copy a paragraph and let the clipboard mode translate it automatically.

The panel stays near the top of the screen, expands only when there is something useful to show, and can copy the result when you need to move it into notes, messages, or a draft.

Images and screenshots are part of the workflow

Some of the most annoying text is not text at all. It is burned into a screenshot, a video frame, a design mockup, or a locked-down web page.

Use the screenshot shortcut, drag over the area you need, and TranslateWindow runs OCR and translation locally. It turns visual text into something you can understand without uploading the image or retyping anything by hand.

What it does

  • Runs as a macOS menu bar utility and stays out of the Dock
  • Supports clipboard translation, screenshot translation, realtime selection translation, and a draggable realtime screen frame
  • Keeps the basic model available by default; Pro unlocks realtime selection, realtime window translation, and the higher-quality advanced model
  • Processes translation locally by design, without sending source text, screenshots, OCR results, or translated text to a cloud translator
