Works very well here on Linux, delighted with this extension. Great contribution to the community!

Exactly what I needed.

it works really good if you only speak english, but if you speak multiple languages, it then moans about me being illiterate and i gotta fix my text.
i dont even know if there is a proper way without using AI to be able to have more than 1 languages and it can detect itself what im using, because i tend to switch between english and swedish very often. i know languagetool did this, but now with them asking people to pay 5$ monthly as if its some movie streaming website and not just a firefox addon for grammar, i'm forced to look elsewhere.

I gave this add-on one more try. Nothing has changed. It's still crap.

Fantastic grammatical add-on from amateur English learners to professional wordsmiths. The complete lack of bloated AI features, paywalls, and major issues makes this a must-have for most Firefox users. Hats off to the developers and I greatly appreciate the work involved to create this brilliant tool!

After LanguageTool got into bed with AI, that was it for me. Having this run locally to run spell check is just what I need.

Language tool is now payware only, I just wanted something to check my spelling and grammar in message and form fields and this does the job 100% and better.

using for week, works great....

pretty great, just a tad bit buggy

This project is both highly effective and beautiful! Thank you for offering a tool that checks every box: free, form, and function!

LanguageTools told me that their browser extension is now for premium members only. After reading that news, LT was removed. The search for a replacement lead me to Harper. After trying Harper for 5 minutes, it was obvious that Harper is the perfect LT replacement. Thank you Elijah!

Basically a good idea, both for privacy and responsiveness.
However it works generally really bad. Doesn't make difference between British and American English, it often flags correct words or makes wrong suggestions, sometimes doesn't even works and it gets stuck at half of the words.

Unfortunately, it needs a lot of work to be a useful alternative to all other high-priced grammar checkers.

So far so good. Love it, but I was testing it just for an hour, so I'll edit my review if anything pops up.

It's not bad, it's just really buggy and unresponsive. I hope this gets fixed

It constantly flags common people names and degrees even with all the filters turned on. Just a pain to use for correspondence.

Big fan of this extension conceptually, but I've found that it just… doesn't work sometimes? :( I have a problem where the Harper editor box will appear within the text box, so I both can't see what I'm typing and can't see the recommended edits. It also struggles with allowing me to accept suggestions sometimes. There have been a few times where I've clicked on a suggestion and it doesn't change anything so I have to manually edit it. I already love the lack of AI being forced onto me as well as the privacy aspect, though. If these issues could be resolved, this extension would be even more fantastic!
