Trayslate 1.5.2 - Free tray translator with hotkeys and configurable services

[AlexanderT]

Hello,

I’ve created a lightweight open-source tray translator for Windows:
Trayslate (a combination of “tray” and “translate”).

Main features:

• Global hotkeys for instant translation
• Works with clipboard and selected text
• Convenient Mouse Mode for keyboard-free translation
• Configurable translation services
• Runs silently in the system tray

The project is open-source and written in Lazarus (Free Pascal).
At the moment, only Windows is supported.

GitHub:
https://github.com/plaintool/trayslate

🚀 New Version is now available!

Since the previous releases, Trayslate has received a number of significant improvements and new features:

• Improved translation workflow — the Popup Window has become more convenient with new controls, language pair switching, Auto Height options, and improved interaction with translated text.
• More powerful Mouse Mode — added new actions to the translate button and fixed several issues that could occasionally cause Mouse Mode to stop working.
• Built-in language detection — introduced and significantly improved automatic language detection, now using a corpus-based algorithm supporting 100+ languages.
• Powerful scripting support — added PascalScript for calculated parameters and response processing, making translation configurations much more flexible.
• More translation services — added configurations for Reverso, Yandex Translate, Lara Translate, LLM7 AI, Google Translate WebTran, and others.
• Improved configuration management — easier configuration editing, reloading, icon management, proxy settings, and additional configuration options.
• New drag-and-drop capabilities — drag text from other applications into Trayslate and rearrange recent language pairs with the mouse.
• Keyboard shortcuts — added hotkeys for Quick Settings and improved hotkey handling throughout the application.
• Better stability and reliability — fixed numerous issues related to translation threads, clipboard handling, popup windows, keyboard and mouse hooks, focus handling, and configuration management.

Overall, these releases make Trayslate more powerful, flexible, reliable, and convenient to use, while keeping its lightweight approach.

It does not compile on Linux.
"Registry" is inside {$IFDEF Windows} block in unit systemtool.
Unit langtool has a useless {$IFDEF Windows} block.
Then there are some Windows specific defines ...

Such an application can be written without any {$IFDEF Windows} or using the "Windows" unit.
LCLIntf ports part of Windows API and LCLType defines Windows compatible stuff.

Hello,
Thank you for your feedback and for reviewing the code.

At the moment, I haven’t built or tested the application on Linux yet. Cross-platform support is planned for future versions. When I start working on Linux builds, I will review and clean up Windows-specific parts and unnecessary {$IFDEF} blocks.

In version 1.0.0, the application is intended and officially supported only on Windows.

When you do get around to Linux (Mac is easy) please have a look at my app, mentioned below. While what you have hopefully done will work with sensible Desktops like Mate, xfce or Cinnamon unfortunately, the most common default Desktop, Gnome, requires heroic efforts to get the System Tray working. Sad but true.

So, start testing with, my recommendation, Mate, to get your confidence up. Then try Gnome and KDE.

Hello Davo,

Thanks for the advice — I’m aware of the system tray issues in GNOME, so that’s something I’ll keep in mind. It might make sense to look into macOS first, since I haven’t had experience building for it yet.

Right now I’m trying to promote the project and improve its visibility to get more downloads and feedback. If you have any suggestions, I’d be glad to hear them.

Is it okay to access Google Translate using REST with AndroidTranslate as User Agent's value?

Hello,

The application itself does not include any built-in integration with Google Translate.
The provided configurations are intended only as examples. If needed, you can use official APIs — for instance, obtain a Google Translate API key and create your own configuration based on it.
The User-Agent used in the example configuration was taken from a popular public repository (similar to py-googletrans), though I don’t remember the exact source.

Best regards,

[AlexanderT]

Thanks for the clarity. It’s important for anyone using or collaborating on this app to understand that translation services have strict TOS regarding indirect access. We want to stay fully compliant to avoid any impact on our users. On a separate note, the app itself is looking great.

There are many projects on GitHub that use Google services by emulating a browser in one way or another. In my case, this kind of logic is not implemented in the code, but the configurations are even more transparent than the code itself.
I am aware that this can be a concern. For now, I have noted it in the disclaimer section of the README.md. I am also considering adding a warning directly inside the application itself to make this more visible to users. I may also take additional measures if needed.
