Free Spell Checker

A first-rate spell checker can help you correct even the subtlest errors.


Did you know that more than three-fourths of us think we’re great at spelling, but a lot of us are overconfident? Spelling can be tricky because it’s not always straightforward. Using the best writing tools can give you confidence that’s well founded.

What is a spell checker?

A spell checker, sometimes referred to as spell check, a spellchecker (one word), or a spell tester, points out words you’ve misspelled when you’re writing on a computer or mobile device. It can be a standalone function or be built into or added to an existing program that you write in.

Many people use spell checkers because spelling in English is tough. These are just a few aspects of spelling that might confuse you:

  • Homonyms are words that sound the same but have different meanings and spellings, such as plain and plane or threw and through. It’s common to get them mixed up.

  • I before E except after C? Sure, unless you’re spelling science, height, caffeine, glacier, weird…and so many other words.

  • With typos, you may end up with words that are spelled right but don’t make sense in the sentences they appear in. For example, you might write “I fed the horse some boats” instead of “I fed the horse some oats.”

  • Besides these challenging aspects, people use different forms of English around the world, with various spellings. In England, you might write that someone ‘enjoyed the flavours of different cultures whilst travelling’, but in America you’d write that they “enjoyed the flavors of different cultures while traveling.” QuillBot’s free online spell check lets you choose which dialect of English you’re writing in.

In short, if you want to make sure your writing is clear to your target audience, getting a spell check online can be a big help.

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.
