AutoCorrect is a software feature commonly found in word processing programs, such as Microsoft Word. As the name implies, this feature automatically corrects misspellings and common typos in a document.
For example, a user may type "my words are not corect" and the program would automatically change it to "My words are not correct." As you can see in this example, not only does AutoCorrect fix the misspelling, but it also capitalizes the first letter of the sentence.
In the animated picture above, you can see AutoCorrect in action. It automatically capitalizes the first letter of every sentence, changing the letter "i" to "I," "auto correct" to "autocorrect," and "ch" to "Computer Hope."
