Add Random Letters to Words

About Random Letter Adder

Random Letter Adder allows you to add random letters inside words in your text. You can control the character pool, the maximum number of letters per word, the chance per word, and where letters are inserted. This is useful for obfuscation, testing, and generating noisy text.

Features

The Random Letter Adder tool provides the following features:

• Custom Letter Pool - Choose exactly which characters can be inserted.
• Max Letters per Word - Limit how many random letters can be added to each word.
• Insert Chance - Control how often words are modified using a percentage.
• Multiple Positions - Insert letters before, inside, or after each word.
• Random Position Choice - When multiple positions are selected, one is chosen at random for each inserted letter.
• Formatting Preservation - Keeps spaces, punctuation, and line breaks intact.
