Frequently Asked Questions

It picks a letter (A–Z, a–z) or digit (0–9) at random and lets you generate as many as you need at once. Output is plain text by default, with one-click export to CSV, JSON, JS array, and Playwright test format.
Each draw uses `Math.random()` and is weighted toward letters: ~45% uppercase, ~45% lowercase, ~10% digits. Each draw is independent. No de-duplication.
Not in the current build, but for uppercase-only test data you can paste the output and filter, or run multiple times and pick. If this is a common need, let us know at support@bug0.com.
It is pseudo-random. Sourced from JavaScript's `Math.random()`, which is suitable for tests, samples, and games, but not for cryptographic use.
Random letters are great for fuzzing form fields, generating unique-ish IDs, seeding screen reader tests, and producing variations of test data that don't collide with real values.
No. Everything runs in your browser. No network calls, no storage, no logging.
Yes. Pick "Playwright test" from the format dropdown. The output is a ready-to-run test loop that iterates over your generated letters.
