Behind every great writer is a great proofreader—here’s yours
With QuillBot, you have the best free proofreading tool in your pocket, on your browser, or in Word whenever you need it.
Writing is a lot of work, and doing it well means revising and revising again. For writers with high standards in every genre and field, online proofreading is an invaluable resource—a must-have. A free online proofreader lets you stop wasting your energy worrying about endless writing mechanics and rules, which frees you up to focus on crafting an outstanding document with a clear message.
What is a proofreading tool?
Proofreading is the last step of editing before a document is published or used—your last chance to make sure your writing is as good as it can be. An automated proofreading tool offers you an excellent, convenient, and reliable way to improve your writing. It reviews the text you’ve written and corrects any spelling, grammar, and punctuation mistakes that are present. As a result, you can be confident that you’re communicating effectively, without errors that are likely to distract readers from your ideas.
These are just a few types of corrections that a free online proofreading tool can suggest to clean up your writing:
Use similar-sounding words correctly, like their vs. they’re vs. there
Clear up confusion about words with similar meanings, like amount vs. number
Make sure nouns and verbs agree, like the dogs bark vs. the dog bark
Correct punctuation errors, like misplaced semicolons or missing commas
Rearrange sentence structures for greater clarity
Double space
