What this tool does

Keyboard Typo Generator creates the kind of typos people actually make, swapping letters for the keys right next to them on a QWERTY keyboard. It produces believable noisy text for testing autocorrect, search, and fuzzy matching against the mistakes real fingers make.

How it works

Paste your text, choose how often to slip, and the tool generates keyboard-adjacent typos in your browser. Copy the output as test data. Nothing is uploaded.
