Frequently Asked Questions
Is each letter equally likely?
Yes! Unlike English text (where E appears most often), our generator gives each of the 26 letters exactly equal probability.
Can I exclude certain letters?
You can filter to vowels only or consonants only. For custom exclusions, generate and filter manually.
Can I generate lowercase only?
Yes! Select the lowercase option before generating.
Is this suitable for cryptographic use?
For casual purposes, yes. For security-critical applications (passwords, keys), use dedicated security tools with cryptographic randomness.
Can I generate other alphabets?
Currently, this tool generates English letters (A-Z) only. Other alphabets would require specialized generators.
Why do I sometimes get the same letter twice?
With true randomness, repetition can occur. Each generation is independent—getting "A" doesn't affect the next result.
