Grammarly is an online spelling and grammar checker and revision support tool. Users can upload texts to Grammarly and receive immediate instructional feedback on grammar, punctuation and spelling.

You may like to explore a free version of this revision tool at Please note that the free version only works in Firefox, Chrome, and Safari. When you open the webpage, it will ask you to add the Grammarly extension to your browser. When the extension is added, follow the on-screen prompts, then select the Free Grammarly version and you are set to upload your documents for review.

If you find the free version of Grammarly useful, you may wish to purchase a premium subscription. The premium version checks an additional 150 grammar points and provides plagiarism detection, vocabulary enhancement suggestions, and a contextual spelling feature. It also provides more detailed explanation of each grammar issue which often includes examples of both correct and incorrect usages. The premium version also asks users to select a paper type, such as essay, presentation or blog to improve the accuracy of the feedback. 

Grammarly is currently offering a 50% discount for ACAP students to purchase a premium subscription at the price of USD $69.99/year. Please go to the 'Student Lounge' space on the Student Portal for instructions on how to take up this offer. We recommend that you first try the free version of Grammarly which has fewer features, but gives a good indication what Grammarly can do.

It is also important to note that once you have purchased the annual premium subscription, it is a rolling subscription, which means Grammarly will continue to deduct this amount from your nominated credit card each year unless you log in and unsubscribe.
