Eloquent is a proofreading tool for English, Spanish, French, German, Portuguese, Polish, Dutch, and more than 20 other languages. It finds many errors that a simple spell checker cannot detect.
It works fully offline, powered by the LanguageTool standalone server.
Eloquent can also run as a service in the background to make your local/offline LanguageTool server available to Firefox, LibreOffice and more.
This is free and open source software.

Hi Steve. That was fast, I only submitted Eloquent yesterday. 🙂
BTW, how do you catalog all of the software and games that you post here on LL. A spreadsheet or database or other?
Keep up the great work.
Cheers.
Thanks for this submission Torin and your kind words.
I mostly use software including OnlyOffice (spreadsheets), RStudio, and WordPress to generate roundups and write articles. All open source goodness.
