Spell checker

Check English spelling in American, British, Australian, Canadian or Indian English, on your device. Free, with no account or uploads.

Check the spelling of your text

Paste or type in English. Each word that looks wrong is shown with its fixes; you choose which to make.

Nothing yet: paste, type or open a file.

Spelling, grammar and punctuation in English are checked on this device by Harper. The checker (8 MB) is fetched once from this site when you press Check; nothing you write is sent anywhere.

English only. Harper is a set of rules, not a person: it can flag what is right and miss what is wrong, and it does not rewrite your style.

A little help along the way

Follow these steps. Every option is explained underneath. Everything happens in your browser; nothing you write is sent anywhere or kept.

  1. Put your text in the boxPaste or type it, or press Open file for a .txt, .md or Word (.docx) file, or drop the file on the box. A line under the box says, as you write, how many words it has and how long it takes to read and to say aloud.
  2. Say what you want to doChoose an answer to “What do you want to do with your text?”: Count it, Change capitals, Compare two texts, Tidy it up, Sort lines, Find and replace, or Placeholder text. Its panel opens beside the text on a computer and under it on a phone.
  3. Count itSee words, characters with and without spaces, sentences, paragraphs and lines. Turn on Check a limit to see how much is left of an X post, a text message, a search description or a word target you set.
  4. Change capitalsChoose UPPER CASE, lower case, Sentence case or Title Case (with its style guide: APA, AP, Chicago or MLA). The panel shows the first line as it will be, and the button changes the whole text.
  5. Compare two textsPaste the first version in the first box and the second in the second. The page says how many words were added and taken out and shows both texts with what was added underlined and what was taken out struck through, side by side or in one.
  6. Tidy, sort, or find and replaceEach panel says first what it will do (“Take out 14 line breaks and 3 double spaces”), then one press does it. Preview the change shows the text before and after with every change marked.
  7. Undo, copy or downloadEvery change is one step: the Undo arrow puts the text back and the Redo arrow does the change again. Copy text puts the text on the clipboard, and the download arrow saves it as a .txt file.

Questions people ask

Can it check British spelling?
Yes. Choose American, British, Australian, Canadian or Indian English under More options; it starts with the one your browser's language points to.
Why is a name marked as wrong?
Harper does not know every name or new word. Press Ignore and that word is left alone wherever it comes back on the page.
Can it check other languages?
No. Harper checks English only, and the page says so; text in other languages may be marked or missed.
