About American English Spell Checker

This spell checker uses an American English Hunspell dictionary, so "color", "center" and "organize" are accepted and the British forms "colour", "centre" and "organise" are likely to be flagged. Paste your text and press Check spelling to see the words that are not in the dictionary. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.

It is a good match for text that must follow US spelling, such as a US school essay, an American business email, a US-facing website or a US publication. It checks spelling only, not grammar, so it will not catch a correctly spelled wrong word.

Names, brands and technical terms are often flagged because they are not in a general dictionary. Choose Add to dictionary to keep them from coming up again in this browser, or Ignore to skip them once.

How to use American English Spell Checker

  1. 1Type or paste your English text into the box. Wait a moment on your first visit while the dictionary loads.
  2. 2Press Check spelling. The possible misspellings appear below the box, in the order they first appear in your text.
  3. 3Click a suggested word to replace every copy of the misspelling in your text, or choose Ignore to leave the word as it is for now.
  4. 4Choose Add to dictionary for a name, brand or technical term you use often. It is remembered in this browser.
  5. 5Press Check spelling again to confirm that nothing is left, then copy your corrected text.

Features

  • Checks English spelling against an American English Hunspell dictionary.
  • Lists each misspelled word once, with how many times it occurs.
  • Up to five suggestions per word, and one click replaces every copy of the word.
  • Ignore skips a word for this session.
  • Add to dictionary saves a word in this browser so it is accepted next time.
  • Works with apostrophes, so "don't" and "it’s" are checked as one word.
  • Shows a word count while you work.
  • Your text is saved in this browser only.

Worked examples

  • The center of the colour wheel. → gives Likely flags: colour

    The American form is "color". "center" is accepted.

Privacy: how it works

  • Your text is checked in your browser tab and is never sent to Ulkaa or to anyone else.
  • The page downloads its dictionary files from this same site the first time you use it. That is a download to your device. Your text is not part of it.
  • The text box and your personal word list are saved in your browser local storage. They stay on your device. Press Clear, or clear site data, to remove the text.

Tips

  • Read your text once more after you click suggestions. A suggestion can be a real word that is the wrong one for your sentence.
  • Add the names of people, places and products you write often to your dictionary, so the list stays short.
  • Check one section at a time for a very long document, so you can read each list of flagged words carefully.
  • Use Ignore for a word you want to leave alone in this document, and Add to dictionary for one you want accepted everywhere.
