Proofreading is a service that involves carefully reviewing and correcting written content to ensure it is free from errors. The main focus is on grammar, spelling, punctuation, and formatting mistakes, but it may also include improving clarity and consistency. Proofreaders typically check for typos, awkward phrasing, and misused words, making sure the text reads smoothly and is polished for publication or submission. The service is essential for academic papers, business documents, manuscripts, and any written material where accuracy and professionalism are important.
