Free Spell Checker (+ Guide)

What is a spell checker?

A spell checker is a tool that compares each word you write with the words it knows, and suggests the right spelling when it finds a mistake.

This one also catches words that should be one word or two, like "alot" for "a lot".

How to check your spelling

A real example

I typed this sentence with US English picked:

The spell checker marked five words, each with its fix one click away:

"colour" is right in UK English, so it's only marked because US English was picked. "their going" and "a example" show up too once grammar and clarity are ticked.

US or UK spelling?

The same word can be spelled two ways, so pick the English you write in first:

Pick US English and "colour" is marked as a mistake, and pick UK English and "color" is.

UK English lets both "organise" and "organize" stand, since Oxford spelling uses -ize, so the checker accepts both.

Words people often misspell

Here are words people often get wrong, with the spelling the checker gives for each:

Each one is marked as you type, and one click fixes it.

More than spelling

The spell checker marks spelling first. Tick the other kinds of mistake above the text, and it marks those too.

For the full check, with how your writing compares with real posts, use the grammar checker.

Is my text private?

The check runs in your browser, so your text isn't sent anywhere while it's checked.

It only leaves your computer when you press Fix it with AI, and I don't keep it.

Who is the spell checker for?

It's for anyone who wants every word spelled right:

• Grammar checker – anyone who wants grammar and punctuation checked too
• How to start a blog – bloggers checking a post before it goes live
• Readability checker – anyone who wants to know how easy their writing is to read
• LinkedIn text formatter – creators writing posts for LinkedIn
• AI humanizer – anyone editing a draft an AI wrote

And if you write for readers in another country, switch to their English and their spelling is checked.
