They help in identifying errors, such as grammar, punctuation, spelling, and others. Furthermore, they ensure consistency throughout the content, which includes the use of proper terms and adherence to the right referencing style, such as APA, MLA, APA, or others. They also enhance the structure, word choice, and paragraph orientation to make the content easier and more understandable. Also, they verify the information included in the assignment, including references and citations. Lastly, they offer suggestions and comments on your content to improve the overall quality.
