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:

Everyday, I ride a new bike.


Every day, I ride a new bike.

Homonyms are words that sound similar but have different meanings and spellings, such as desert and dessert 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.
