What Add Random Letters to Words Tool can do:

This tool inserts a fixed number of random letters into every word of your text. You can control where the letters go and whether they appear in uppercase or lowercase. It’s ideal for obfuscation, testing, or just seeing what your app does with mangled words.

Example:

Input Text:

Hello world

Options Selected:

• Letters per word: 2
• Insert Position: Middle
• Uppercase letters: On

Output:

Common Use Cases:

Useful for data noise testing, input validation, stress-testing search systems, creative distortion of readable text, or generating weird variations of real content for game text, puzzles, or CAPTCHA-like challenges.

Useful Tools & Suggestions:

If you’re exploring distortion, Create Text Typos works similarly but focuses more on keyboard-style mistakes. And when you want to mess with structure at the word level, Scramble Words gives you that jumbled, unpredictable feel without changing the word count. Both are great for testing resilience or building glitch-style effects.
