Frequently asked questions

What is the difference between Title Case and Sentence Case?

Title Case capitalizes the first letter of each major word while keeping short conjunctions and prepositions lowercase (e.g. 'The Old Man and the Sea'). Sentence case capitalizes only the first letter of the first word in each sentence and proper nouns.

Can I convert text into programmer casing like camelCase or snake_case?

Yes! DocMate includes dedicated conversion algorithms for camelCase (e.g. 'userId'), PascalCase ('UserId'), snake_case ('user_id'), and kebab-case ('user-id').

Is my text saved or stored on any server?

No. All text parsing and manipulation occurs purely inside your browser using client-side JavaScript. Your text never leaves your device.
