Top 10 Best Grammar Checkers for Proofreaders

Proofreaders aren’t infallible. Although you know all the grammar rules and what to do with that comma over there, there are times where you’ll miss something out. It happens to the best proofreaders. This is where a grammar checker can come in to give you a hand.

Grammar checkers aren’t perfect themselves, but they offer a way of spotting the most obvious errors. If you’ve missed something out, a good grammar checker can come to the rescue and save you some embarrassment.

Here are ten of the best grammar checkers you should consider using.

  1. is an online grammar checker. All you have to do is copy and paste your text into the box and it points out any errors. There’s no need to register or pay a fee. There are no restrictions on how often you can use it.

  1.       Proofread Bot

Proofread Bot covers multiple bases. It deals with grammar, but it also points out stylistic issues, such as use of the passive voice. This online checker doubles as a plagiarism checker. It’s not as proficient as plagiarism checkers like CopyScape, but it catches most obvious signs of plagiarism.

  1.       Instant Grammar Check

Instant Grammar Check is an online proofreading and plagiarism option that points out grammar errors and instances where the writer may have plagiarised someone else’s work. Unfortunately, you have to run a free trial. If you like it, you have to pay to continue to use it.

  1.       PaperRater

This grammar checker was designed for students who wanted to go over their papers before they submitted it to their teachers. It’s still useful for professional proofreaders, however. As well as being extremely accurate at finding errors, it’s available entirely free of charge. There are no downloads required to use PaperRater.

  1.       After the Deadline

After the Deadline is about as simple as it gets, where online grammar checkers are concerned. You don’t have to sign up for an account or hand over any personal information.

To make it even easier, all errors are underlined in different colours, according to the type of error, allowing you to see everything at a glance.

  1.       PC Pro

If you’re specialising in British English, PC Pro is the perfect grammar checker for you. It makes sure you haven’t inadvertently applied a US grammar rule to your work. Another advantage of PC Pro is it’s mobile friendly, so you can carry out your proofreading duties on the go.

  1.       Spell Check Plus

This advanced grammar tool will scan your document and point out everything from misplaced commas to misspelled rules. The only downside is you can only check 2,000 words at once.
