What does it do?
Checks the accuracy of spelling, punctuation and grammar as well ad giving your feedback on the tone of your writing.
What can I use it for?
Great for proofreading your work as it will pick up on far more errors than MS Word as it checks context as well as spelling errors. You can use it to proofread essays, emails to lecturers and even social media posts. You can also use it to make sure you have got the right tone in what you have written, giving you confidence when writing to friends, peers and lecturers.
Cost? Free! Premium subscription is also available but the free version is excellent.
Where can I find it? You can sign up/log in via your Google or Apple account and there is a free plug-in for Google Chrome and Microsoft Word so you can access it directly in your Word documents. For further information you can take a look here.
