Frequently Asked Questions

Does the Title Case algorithm capitalize prepositions?

It depends on the grammatical rule set. Generally, short prepositions (under four letters like 'in', 'on', 'at') are lowercased, while longer prepositions (like 'Between' or 'Through') are capitalized. Our tool follows standard web and AP style rules by intelligently lowercasing common short articles, prepositions, and conjunctions unless they are the very first word.

How do developer cases handle punctuation?

When you select a developer format like camelCase, snake_case, or kebab-case, the internal algorithm automatically strips out punctuation marks (commas, periods, exclamation points) to ensure the resulting string is a valid, syntax-safe programming variable or URL slug.

Is my confidential text saved or monitored?

No, absolutely not. The formatting logic runs entirely on your local machine using your browser's processing power. Nothing you paste into the input box is ever saved, tracked, or transmitted over the internet.
