Private + open source + free to run your own instance? That's amazing.

LanguageTool browser addon is no longer open source. Only the desktop app is open source.

Tried a number of others and LanguageTool was the only checker that did not mess with the underlying HTML in the document. I often need to switch between the WYSIWYG and the HTML view when editing website content. Other grammar checkers would mess with the content and even break it.

LanguageTool does not respect your privacy as they claim, they actually store and have real people reading what you type in certain occasions, and they also track you through multiple devices using Google Analytics. I will post two texts that were taken from their page about privacy, you can read it all at https://languagetool.org/legal/privacy.

“If you explicitly ignore corrections, we log the internal rule id of that error and the text fragment marked as incorrect (i.e. the small part of the sentence that was underlined as an error) and 15 characters to the left and to the right of the fragment. This enables us to analyze and avoid false alarms.”

“This website uses Google Analytics, a web analysis service of Google LLC ("Google"). The use includes the "Universal Analytics" operating mode. This makes it possible to assign data, sessions and interactions across multiple devices to a pseudonymous user ID and thus analyze a user's activities across devices.”

Open source doesn't track you and works perfectly and fast.

A Wonderful Privacy-Focused Alternative to Grammarly.

Very questionable support for non-Latin languages. Too many minor mistakes. Just find some native speaker or translator.

Open source, free, multi-language support and offline tools. Just awesome. Also, they added Overleaf support now :)
