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.

Helpful at all times ...

Great and useful!! Maybe more expensive ... I'll let you know!!

I love Grammarly for FireFox! I am a person of (arguably) average or above intelligence with a large vocabulary who writes a lot. For reasons that would bore you, I never learned grammar well in school. The quality of grammar in my routine emails has increased dramatically since using Grammarly. Often I will take advantage of hints or explanations offered by Grammarly. Sometimes Grammarly make a recommendation I don't like and I ignore the recommendation...like using ellipses:). Grammarly on FoxFire has been a great resource to me.

Grammarly is pretty awesome. I write occasional papers for school and appreciate having that extra help I get from them. I also like the progress summary email telling me how I did the previous week.

very good

It is awesome and it helps with my emailing's to other people.

Fixes all my typos.

An excellent program.

I like it because it's helped me keep track of my writing mistakes and I like it because it was made with LISP. Long live the LISP programming langauge!

Very useful for writing

It's wonderful for emails. My girlfriend lives an hour away and I write her almost daily. I usually write my letters in Word, use Spellcheck and then copy and paste it into an email. Despite having written and published almost a hundred articles, I seem to be comma-challenged. Grammarly helps out a great deal.
