What is AI Proofreading?Should we use AI Proofreader?

If you frequently use Microsoft Word as your writing tool, you might have noticed its built-in spell check feature. You might think it's useful, but it's not powered by AI. MS Word simply checks each word you type against its dictionary. AI proofreading tools are more than just spell checkers. They are actually grammar and style checkers. These kinds of errors are harder to detect than spelling mistakes.

AI proofreading is a revolutionary technology that analyzes and corrects written content for grammar, spelling, punctuation, style and coherence errors using advanced natural language processing (NLP) algorithms and machine learning techniques. It goes beyond the most basic spelling check based on a dictionary.

Since ChatGPT was released, people have often used it as an AI tool for writing or proofreading.

The chatbot-style input prompts may give the impression that ChatGPT can handle any question. However, to get satisfactory answers, you often need to provide very detailed and precise prompts because it's not specifically tailored for editing or proofreading.


If you want to enhance the efficiency of your writing tasks, consider using professional AI proofreading tools. In this article, I will introduce the top 5 free AI proofreaders available on the market, including both online options and desktop-based Office integrations.
