How it works
How it works
Input is split into tokens using non‑alphanumeric separators. Each mode applies a simple transformation:
- lower/upper: Unicode case mapping via JavaScript
toLowerCase/toUpperCase. - Title: Capitalizes the first letter of each token (not grammar aware).
- snake/kebab: Joins lowercase tokens with
_or-.
Privacy & Security
No server calls are made.
Accuracy, Limits & Tips
