Program works nicely with Thunderbird but their pricing model needs to be revisited. Way too expensive as spell check feature is already in Thunderbird. They would gain many more customers and have better cash flow if their pricing was revisited

Great app, does the work it's said to do, and seems to help very well with teaching how to use comma's and how to write sentences correctly.

HOWEVER!
If you are a fast writer, then I CANNOT with good conscious recommend this app.
While I was making a long comment on Facebook, the process was made longer by having this app enabled while writing, because the app could not keep up with my speed of writing, and caused Firefox to run very slowly and laggy, making me wait a second or two before I would be able to see what I've just written, and words would more often than not be jumbled into each other as I had not paused a split second between each fully spelled word so that the app could keep up with controlling words and sentences.

As soon as I had disabled the app, everything went smoothly and perfectly again, and I could write at my own speed again with no laggs or anything.

If the creator can somehow fix this issue, then I would give the app top rating, but seeing as how I want to write at my own speed with no issues, I cannot give this a better score than a 3 star score.

Nice add-on

This is so useful, it shows the errors, spelling and Grammar, you even learn after a while..

Very good for me as I'm a casual user.

It is as good as it is possible, but when someone texts me messages, their English mistakes are assigned to my account, as if I had made them.

wonderful concept easy to use

My personal and professional life is heavily involved with the expression of ideas and concepts. I greatly appreciate Grammarly for its' ease and impact as it works in the background to improve my accuracy and word choice. Over the years, the program has assisted me with literally thousands of articles, documents, research articles, poetry, proposals, training materials, etc. Thanks Grammarly for being this writers best friend!

It's a great Add-on. That's all I really have to say.

Grammarly takes the guess work out of sending emails or documents. Whatever I am posting I am confident that I am using proper grammar and spelling

I use the free version now, and I find it very useful for someone who don't speak English natively. It doesn't show you the vocabulary mistakes only but the grammar and syntaxic ones.
I really love it but I though the fees of monthly or annually version a few expensive for students.

Thank you for Grammarly...

Love this program for its help in catching multiple grammatical errors. One thinks you learned all you need to know in grade school, yet still, I make mistakes. English is hard.

My writing experiences by use of 'grammarly' has given me more depth in writing English in its proper form . Liked it very much.

I have been using this add-on for the past week, it is very good at catching errors. I have dyslexia and software such as this is a very important part of my workflow.

I like Grammarly because it helps me use proper grammar, conciseness, & punctuation, etc. My writing has improved.

Though some features are missing in the free add-on of grammarly, still I felt a positive impact in my writing for this. I would highly recommend anyone to use this add-on with the mozilla browser.

fantastic way to be sure I am spelling and writing correctly.

Can't afford to buy it. I use for free what it allows, and I like it

Hi just rest p/w, the service is perfect thank you jim thomas

I am using a lot this extension, sometimes (rarely) frozen but it really helps non-native speakers to improve the vocabulary and to write better in English. Current I have the premium access. I love it!

So usefull

Great help, especially for an oldie like me!

Grammarly has helped me improve my writing skills.
