Is my text uploaded or stored anywhere?
No. Conversion happens instantly in your browser — your text is never sent to a server, never stored, and disappears when you close the tab.
What's the difference between Title Case and Sentence case?
Title Case Capitalizes Every Word (used in headlines); Sentence case capitalizes only the first word of each sentence, like normal writing.
What are camelCase, snake_case and kebab-case for?
They're programming naming styles: camelCase joins words with capitals (JavaScript variables), snake_case uses underscores (Python), kebab-case uses hyphens (URLs and CSS).
