QuillBot's free spell checker will automatically find and correct your spelling errors. Our spell checker will improve your writing and allow you to convey your message clearly.

How does QuillBot’s spell checker work?

QuillBot's online spell checker is powered by AI and is part of QuillBot’s overall editing function, which makes it more effective. You can paste a section of a document into the spell checker box on QuillBot’s website or just type something in that you need revised. QuillBot will review your writing and show you where any spelling errors might be lurking by underlining them in red. Then you can click the Fix All Errors button to correct your spelling.

Or, if you’re typing on another website, such as filling out a form, our browser extension is just what you need. Install it and sign in, and you’re all set! Its Grammar Checker gives you a built-in word corrector on almost any website you visit using Chrome or Edge.

QuillBot spell checker FAQs

Spelling correction is built into QuillBot’s functionality, so when you install our Chrome browser extension, it adds QuillBot to Google Docs, and an editing box appears in the right margin of your document. You can use it the same way you would use our website’s text box.

Some spell checkers don’t help you catch spelling errors caused by typos or misused words, but QuillBot’s spell check does because it looks at more than just each word individually. It considers the context—the subject and meaning of a sentence—along with the spelling and meaning of a word.
