Stay in the window you are reading

One gesture from screen to meaning.

snapTrans compresses capture, recognition, translation and reading into one natural action.

  1. 01

    Press the shortcut

    Alt + Q by default. A reliable text selection is read directly; otherwise, screen selection opens.

  2. 02

    Release the mouse

    There is no confirm button. Local OCR and language detection begin as soon as the region is set.

  3. 03

    Read in place

    The translation streams into the original region. Copy it, reverse the direction, or keep working.

Designed around real work

The capture is only the doorway.

Use foreign-language sites, desktop software and structured tables without carrying content into another translation window.

The essential flow

Local recognition, streaming translation

RapidOCR extracts text on your PC. Only recognized text goes to the model provider you choose. DeepSeek, LiteLLM and other OpenAI-compatible APIs are supported.

Capture and mark up

Rectangles, ellipses, arrows, text, pen, mosaic and numbered notes in a toolbar that follows the selection.

Scrolling capture

Control every scroll yourself, watch the stitched image grow, and finish whenever the content ends.

Table extraction

Local OCR infers regular rows and columns. Review the cells, then copy TSV or Markdown.

Multi-monitor and high DPI

Coordinate mapping is built for mixed Windows displays and scaling ratios, where capture tools often drift.

Privacy without vague promises

Your screenshot stays on your computer.

Capture and OCR run locally. Recognized text is sent to your configured model provider only when you request translation, explanation or summarization.

Common questions

A few things worth knowing.

Do I need an API key?

Not for capture or local OCR. Online translation needs a key for DeepSeek, LiteLLM or another OpenAI-compatible provider. Your provider may charge separately.

Does the model receive my screenshot?

No. RapidOCR recognizes the screenshot locally and snapTrans sends only the resulting text for translation.

Is macOS supported?

The current release target is Windows 10/11. A Mac version is planned, but capture permissions, shortcuts and secure key storage require native adaptations.

When will it reach Microsoft Store?

MSIX packaging, privacy materials and Store certification are being prepared. Email us for launch updates.
