Frequently Asked Questions
- How is the case randomized?
- Each letter independently has a 50% chance of being uppercase or lowercase, so every run produces a different result — unlike Alternate Case, which follows a fixed even/odd pattern.
- Why generate randomly-cased text?
- Fuzz-testing case-insensitive matching and validation logic, creating meme-style text with an organic look, and producing varied fixtures for normalisation code.
- Is my data private when I use this tool?
- Yes. This tool runs entirely in your browser using client-side JavaScript — nothing you type is transmitted to, logged by, or stored on any server. You can safely process confidential text, tokens, or code.
