Our list of the best human and AI editing grammar checkers of 2022 below will help you find a high-quality spelling and grammar check.

Human Grammar Checkers

A human grammar checker can cater to your specific needs while editing your document.

Although a human editor is unlikely to provide a free grammar check (unless they offer a free sample), they are generally highly educated and experienced. This allows them to edit your writing with high accuracy while simultaneously analyzing its context, which most editing tools are unable to do on their own (that is, without the help of a human English expert like an editor). 

For example, a human editor will know early on if your document requires editing or proofreading. They'll also pay particular attention to your document's type during the editing process. 

This is important because different document types come with different sets of needs. For instance, an admissions essay edit requires a vastly different approach than a book edit.

In addition, a human editor can provide subjective feedback, which is important, especially for creative writing. However, this also generally means that their edits will take longer to complete than those made by an AI sentence checker.

Finally, a human English text corrector often has subject-matter expertise. In contrast, online AI grammar checks lack such expertise.

Advantages of Human Grammar Checkers

  • Cater edits to your specific needs
  • Provide context-specific revisions and subjective feedback
  • Offer subject-matter expertise

Disadvantages of Human Grammar Checkers

  • Typically cost more than AI grammar checkers
  • Generally slower than AI grammar checkers

AI Grammar Checkers

AI grammar checkers are becoming increasingly popular due to their ease of use, editing speed, and affordability. Most AI grammar checkers allow for free online grammar checks.

AI editing tools can provide quality editing, but it can be difficult to determine which revisions are actually correct without having a background in grammar. This is important to keep in mind if you wish to use AI grammar correctors without consulting a professional editor.

When AI tools aid human editors, companies can harness the power of editing tools and the experience and education of human editors to provide top-quality edits.

AI editing tools may also fail to consider your document's type or any specific editing needs you may have. In addition, they are unable to provide feedback on the content of your document, especially with regard to subject-matter specifics.

However, in general, AI grammar checkers are becoming increasingly powerful. They typically provide revisions for an entire document within seconds, which is impossible for human grammar checkers.

Advantages of AI Grammar Checkers

  • Easy to use
  • Generally provide quick, if not instant, revisions
  • Usually free

Disadvantages of AI Grammar Checkers

  • Difficult to tell when incorrect revisions are suggested
  • Typically unable to provide feedback
