How does ProWritingAid's spellchecker work?

ProWritingAid's spellchecker is part of an even greater tool—an AI-powered grammar checker, style editor, and writing mentor. You'll get suggestions for improvements far beyond just spelling.

Let your writing shine

Grammar rules are important to remember, but let's face it, there are a lot of them. ProWritingAid has an arsenal of preprogrammed grammar rules, so you don't have to rely on your memory. As you check your spelling, you'll see possible punctuation mishaps, subject–verb agreement issues, and other grammar errors.

Improve clarity and readability

Checking that your words are spelled correctly is just one part of good writing. You'll also want to ensure that your writing is easy to read. The spellchecker's built-in readability report will zone in on areas where your language is a little too complicated.

Make your own rules

There are times when the spellchecker may flag a word as misspelled when it's actually not, such as a newly created character name. With ProWritingAid, you can create your own dictionaries where you can add specific words and jargon. You can also create snippets and style guides that fit your writing needs.

Who can benefit from an online spellchecker?

ProWritingAid's spellchecker is for every writer who wants to share their work confidently.

Creative Writers

If you're an author, you'll want to do as much groundwork as you can before hiring a proofreader. If you're a blogger or social media manager, then you know that sting when a typo makes it into your post. Get it right the first time.

Students

Misspelled words distract from the essence of your essay. They also make your work appear lazy. Improve your grade and show your professors you're serious about your education.

Business Writers

Imagine a client pointing out a typo in your proposal. Doesn't seem very professional, does it? Inspire confidence by ensuring all your business communications are error-free.

ProWritingAid is used by every type of writer

ProWritingAid has been a godsend for me. I am currently rewriting all of my eleven books using this program. I can't believe what I missed first time around. This is the next best thing after a human editor. I love it!

The ProWritingAid extension has been incredibly helpful. I do a lot of academic writing directly in Chrome, and being able to use ProWritingAid without switching tabs or using the desktop app makes things a lot faster.

I use ProWritingAid every day as I create content for my B2B clients. Been relying on the program for about 3 years. The software has helped me improve my writing.
