Microsoft Word and Google Docs both have inbuilt grammar checkers which add a line under potential mistakes and offer suggestions. It can be helpful to use this function thoughtfully to see where you have made errors so you can correct them. However, trusting them completely and making changes without being aware of why something has been highlighted as an error can cause problems as the suggestion may not convey the meaning you want. Using the inbuilt function to spot errors is a good start, but it is also good to understand why it is grammatically incorrect. The same advice applies to grammar apps like Grammarly and also generative AIs. Generative AIs can be 'too helpful' and offer to rewrite sections completely. This can alter the meaning and take away the control you have over the final document. Instead, it is better to ask an AI for feedback, for example: 'Give me four bullet points on how I can improve my grammar in this assignment', because you can then decide which suggestions you choose to implement. If you are unsure whether your use of grammar checkers oversteps the boundaries of good academic practice, see Brookes' guide to using proofreading and editing technology.
