Frequently asked questions
What's the difference between Title Case and Capitalized Case?
Title Case follows headline convention: short articles/prepositions (a, of, the…) stay lowercase. Capitalized Case upper-cases every word regardless of role.
Which case should I use for code identifiers?
camelCase for JS/TS variables, PascalCase for types/classes, snake_case for Python, kebab-case for URLs/CSS classes and file names — all available here.
Is any text transmitted?
Never. Conversions run on-device per keystroke.
