Grammarly
Grammarly acts as your collaboration partner in every stage of the writing process—helping you brainstorm initial ideas, format citations accurately, and everything in between, so you submit your best work with integrity.
NOTE: Google Docs on an iPad is really a Google Doc App. It does not have the same grammar functions as the web version of Google Docs. Use Grammarly to support student writing.
