From there, you will have a bunch of options to choose from when it comes to correcting your work. Once you are logged in, you’ll be taken to the Grammarly dashboard. It’s important to note that if you want to make any corrections to your document, you’ll have to make a Grammarly account using your email, Facebook, or Google login. The other method is by downloading the Grammarly desktop app to your computer and uploading your saved LibreOffice text. Grammarly does have compatibility with your browser extension so you can download it and use the LibreOffice writer program to use it that way or you can use the other method.
