A lightweight Windows 11 background utility that captures any screen region, performs OCR, translates the text, and overlays the result directly on the original location.
- Hotkey-triggered screen capture — press
Ctrl+Shift+Tto select any region - AI-powered OCR + Translation — a single API call recognizes text and translates it
- Smart overlay — translated text is positioned where the original text was; falls back to a readable word-wrapped view when the content overflows
- Pluggable AI backends — OpenAI-compatible and Google Gemini, with configurable base URL / model / API key
- Auto-detect source language — only set your target language
- Copy & Save — right-click the overlay to copy text or save the image
- System tray — runs quietly in the background
- Download
TransIt-Windows-x64.zipfrom the latest release. - Extract and run
transIt.exe. - Right-click the tray icon → Settings.
- Choose a backend and enter your credentials:
| Provider | Backend | Base URL | Model (example) |
|---|---|---|---|
| Alibaba Qwen | OpenAI | https://dashscope.aliyuncs.com/compatible-mode |
qwen3-vl-flash |
| OpenAI | OpenAI | https://api.openai.com |
gpt-4o |
| DeepSeek | OpenAI | https://api.deepseek.com |
deepseek-chat |
| Gemini | (built-in) | gemini-2.0-flash |
- Press
Ctrl+Shift+T, drag to select a region, and the translation appears.
Any provider that exposes an OpenAI-compatible /v1/chat/completions endpoint works out of the box. Set the Base URL, Model Name, and API Key in Settings.
TransIt stores settings in the Windows Registry at HKCU\Software\TransIt.
To clean up after deleting the executable, run the included uninstall.bat (or manually delete the registry key).
