Use Cases

  • Form field fuzzing

    Generate random letter input to stress-test form validation.

  • Unique-ish test IDs

    Quick random strings for short test identifiers and fixtures.

  • Captcha-like text

    Generate sample text for testing OCR, screen readers, or accessibility flows.

  • Pick a letter A–Z

    Educational use. Draw a random letter for word games or alphabet exercises.

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.
Click "Pick a random letter" and one letter is drawn from your chosen character set using `Math.random()`. Each draw is independent, so repeats are possible.
Yes. Toggle the character-set options: uppercase A–Z, lowercase a–z, and digits 0–9 are independent, and you can exclude vowels. Leave only uppercase checked for uppercase-only output. The options apply to both the single pick and bulk generation.
Yes. Enable "Exclude vowels" to remove A, E, I, O, U (both cases) from the pool, which is handy for consonant drills and word games.
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.
