With this online tool, you can introduce subtle random mistakes in the given text. The program randomly replaces letters and symbols in the text with new random characters, thereby adding a level of inconsistency to the content. This operation is useful for creating tests for content filters and creating puzzles that require finding and correcting mistakes in the text. There is a range of options to customize how the errors are added to the text. The first set of options allows you to choose which character categories to add errors to. These options include adding errors to letters, numbers, whitespaces, and punctuation. In addition, you can add errors to other characters that are not covered by these classes by entering them into the appropriate options field. The "Error Percentage" option allows you to determine how frequently the errors are introduced in the text. For example, if it's 50%, and the checkbox "Add Errors to Letters" is selected, then half of all letters in the text will be replaced with other random letters. In the "Error Symbols" options field, you can insert additional symbols that will be used for creating errors. This options field can include alphabet letters, numbers, punctuation marks, and even Unicode glyphs and emojis. The "Add Errors by Category" option allows you to choose how the errors are added to the text. When this option is on, the utility adds errors to letters by replacing them with other letters, creates numeric errors only in numeric data, and replaced punctuation symbols with other punctuation symbols. Finally, the "Keep Letter Case" option ensures that the errors are made using the same letter case as the original letter at that position. Textabulous!

In this example, we add errors to a quote by Marcus Tullius Cicero. We only distort the letters by randomly replacing them with other letters. We set the error rate to 25% (a quarter of all letters) and enable the "Keep Letter Case" option so that the case of capital and lowercase letters is maintained.
In this example, in order to test an automated letter sorting system, we added errors to a postal address. We mangled the numbers in it by selecting the appropriate checkbox in the options ("Add Errors to Numbers"), as well as the capital letters by listing them in the additional characters field. For the new error symbols, we use Roman numerals, which now randomly appear in half of the numbers and capital letters.
In this example, we add errors to letters, numbers, spaces, and punctuation marks and distort 15% of the entire text. We use the "Add Errors by Category" option to replace each symbol with a symbol from the same category. In particular, we replace letters with uppercase vowels "AEIOU", numbers with just other numbers "4" and "6", spaces with tabs "\t", and punctuation marks with colons ":".
