Create Text Typos

The Create Text Typos Tool introduces controlled errors into your text by mimicking real-world typing mistakes. It supports common typo types like keyboard neighbor swaps, letter transpositions, missing characters, or extra inserted characters. You can fine-tune how many typos occur per word, skip short words, or apply errors to every word for heavier mutation.

How to Use:

  1. Paste your text into the input box or upload a .txt file using Choose File.
  2. Select a typo generation mode:
    • Keyboard Neighbor: swaps letters with adjacent keyboard keys
    • Transpose Letters: reverses adjacent characters
    • Missing Character: randomly deletes one or more characters
    • Extra Character: inserts random letters into words
  3. Use the toggle switches to:
    • Apply typos to every word
    • Avoid short words (3 characters or less)
  4. Set the Typos per word limit (e.g., 1–5).
  5. View the altered result instantly in the output area.
  6. Use Copy Output or Export to File as needed.
  7. Click Clear All to reset.

Example:

Input:

The quick brown fox jumps over the lazy dog.

Output (Keyboard Neighbor, typos per word = 1):

The qiuck btown fox jymps oveg rhe lazy dpg.

Common Use Cases:

Use this tool to simulate input errors for testing auto-correction tools, CAPTCHA systems, or AI text cleanup. It’s also useful for generating distorted text for data augmentation, training typo-resistant search, or simply creating glitchy-style copy for informal applications.

Useful Tools & Suggestions:

If you’re generating typos, Add Fuzziness to Text can layer in even more randomness perfect for testing spellcheckers or simulating human error. And once you’re done experimenting, Highlight Words in Text helps you spot which terms were altered without digging through every line manually.
