Online proofreading tools instantly polish your writing, so it’s become widespread among professionals to have one. But with so many tools on the market, it’s difficult to know which is best.
In this article, we’ll cover the most popular online proofreading tools on the market today. But first, let’s briefly cover what you should expect from one.
How to Choose an Online Proofreader

A good online proofreader knows what document you’re writing and will be able to provide suggestions accordingly. Narrow your focus to creative, business, academic, or general proofreading.
Next, consider what features you need. More advanced proofreading tools go far beyond basic grammar and spelling checks.
For example, some let you rewrite entire paragraphs to improve readability, while others offer developmental feedback—focusing on big-picture elements like story structure, character development, plot consistency, and identifying strengths or weaknesses in your narrative.
Finally, where do you want to use the tool? Some proofreading software offer extensions so you can work anywhere online. Others integrate specifically with Microsoft Word or Google Docs. This is more important than you might think because you can lose time formatting when you copy and paste.
Of course, you need to consider your budget too. Some software is more expensive than others—and remember, many tools offer a free version, allowing you to test it first before buying.
