Transinline

Transinline is a tiny Windows tray app for translating selected text anywhere.

Select text in Okular, a browser, Word, or any app that supports Ctrl+C, press your configured hotkey, and a small popup appears near the cursor with the translation.

Persian README: README.fa.md

Features

• Works across different apps
• Light and dark mode support
• Google Translate, Abadis (for Persian), or both
• Configurable provider, source and target languages
• Optional startup registration for Windows sign-in

Requirements

• Windows 10 or newer
• .NET Desktop Runtime 8

Download And Use

1. Open the GitHub repository page.
2. Go to Releases.
3. Download the latest Transinline.zip.
4. Extract the zip somewhere permanent, for example C:\Apps\Transinline.
5. Run Transinline.exe.
6. Select text in any app.
7. Press Ctrl+Alt+T.

Keep these items together in the extracted folder:

• Transinline.exe
• transinline.config.json
• assets

You can also build the app yourself from source with the commands below.

Config

Edit transinline.config.json next to the exe:

{
  "hotkey": "Ctrl+Alt+T",
  "provider": "google",
  "sourceLanguage": "auto",
  "targetLanguage": "fa"
}

Supported providers:

• google
• abadis
• both

Supported hotkey examples:

• Ctrl+Alt+T
• Ctrl+Shift+Q
• Alt+F8

Language codes use Google Translate-style short codes:

• sourceLanguage: auto, en, fa, de, ...
• targetLanguage: fa, en, de, ...

Notes:

• Fn usually cannot be registered by Windows apps because it is handled by keyboard firmware.
• Win+T is reserved by Windows on many machines.
• The app reloads the config automatically after you save it.
• Abadis is only used for English-to-Persian lookups in this app.

Startup Registration

Transinline is an interactive tray app, so it should not run as a real Windows Service. Windows Services run in a background session and cannot reliably read selected text or show a popup on your desktop.

Use startup registration instead:

.\Transinline.exe --install-startup

Remove it:

.\Transinline.exe --uninstall-startup

Check status:

.\Transinline.exe --startup-status

The tray menu also includes startup registration commands.

For convenience, --install-service, --uninstall-service, and --service-status are accepted as aliases for the startup commands.

Build

dotnet build

Publish

dotnet publish -c Release -r win-x64 --self-contained false -p:PublishSingleFile=true -o .\publish

The publish output includes:

• Transinline.exe
• transinline.config.json

How It Works

When the hotkey is pressed, Transinline waits for the hotkey keys to be released, sends Ctrl+C, waits for the clipboard to update, restores the previous clipboard text, then translates the captured selection.

This keeps the app simple and lets it work across many Windows applications.

Limitations

• Apps that block copying selected text cannot be translated.
• Abadis is a dictionary site, so phrase and sentence results may be sparse.
• Google translation uses an unofficial public endpoint and may change.
