What is a spell checker?

A spell checker is a software facility that highlights misspelled words in a text and suggests correct words to fix these misspellings. The first spell-check system was developed by a group of six linguists from Georgetown University in the late 1970s for the mainframe computers produced by the IBM Corporation.

How do I use your online spellchecker on my computer?

If you know how to copy and paste text (for example, in Microsoft Word), you basically know how to use our online spelling checker tool. After you've copied your text, paste it into the box near the top of the screen and click on "Spell Check." A pop-up dialogue box with your original text will appear. Spelling errors will now be highlighted in red and if you right-click on them, you will be provided with a list of possible correct suggestions and other options. Grammar and style errors will be highlighted in yellow. If you added new text inside the pop-up window, you can always re-check it again by clicking the "Check text" button. When you’ve checked your text, just click the "Finish Checking" button to complete your session.
