Get started

  1. Run snapTrans; it will stay in the system tray.
  2. Open Settings and enter the API key, endpoint and model name.
  3. Check RapidOCR status and save.
  4. Select text or press Alt + Q to translate a screen region.

Translation does not respond

Run Connection Test in Settings. Check the API endpoint, exact model ID and account balance. OpenAI-compatible endpoints often end in /v1; the DeepSeek default is already configured.

OCR is unavailable

Keep the RapidOCR-json folder beside snapTrans.exe, or select the full path to RapidOCR-json.exe in Settings.

The selection is offset

Tell us the number of displays, scaling ratio of each display and primary-display position. DPI and cross-display issues need these details for reproduction.

Shortcut conflict

The defaults are Alt + Q for translation and Alt + W for screenshot markup. Choose combinations not already used by another app.
