How to Introduce Errors into Text

The Introduce Errors tool (also known as a Typo Generator) simulates human typing mistakes in your text. This is useful for testing the robustness of spell checkers, search algorithms, or creating "natural-looking" informal text.

Error Types

  • Swapped Letters: Transposing adjacent characters (e.g., "teh" instead of "the").
  • Missed Keys: Skipping a character (e.g., "writng").
  • Wrong Keys: Hitting a nearby key on QWERTY layout.
  • Double Hits: Accidentally repeating a character.

Use Cases

  • Testing fuzzy search implementations
  • QA for spell checking software
  • Creating data for OCR error correction training
  • Simulating hasty user input
