FAQ

Title case rules vary—why?

Chicago vs AP vs brand guides disagree on small words (“and”, “of”). Automation cannot know your style guide; tweak output manually for marketing headlines.

All-caps acronyms?

Naive title casers lowercase `NASA` into `Nasa`; fix exceptions by hand or maintain a dictionary in code for production pipelines.

Multilingual edge cases?

Turkish dotted/dotless I, German ß casing rules need locale-aware libraries; browser `toUpperCase` follows implementation locale quirks—verify for legal docs.

Accessibility?

Screen readers use original text; shouting in ALL CAPS can sound aggressive—use styling instead of caps lock when possible.

Programmatic vs this tool?

Bulk transforms belong in editors or ETL; this page helps quick one-off pastes.

Privacy?

Local transforms only.
