Grammarly Alternative - Microsoft Editor
Grammarly is not recommended for use on school computers for security reasons--it can upload anything you type to its own servers in order to provide writing analysis and feedback.
As an alternative, please consider using Microsoft Editor, which is a comparable product.
To start using Microsoft Editor
Visit the following web page and sign in. Editor will then be added to your SU Office 365 identity.
