Frequently asked questions
What's the difference between alternating and random mode?
Alternating strictly flips case every letter for the classic evenly-patterned look; random mode assigns each letter's case independently, giving a less uniform, messier result.
Does this affect numbers or punctuation?
No, only letters have a case to change — numbers, spaces, and punctuation pass through unchanged.
