Questions
- What is the difference between Title Case and Sentence case?
- Title Case capitalises the first letter of every word, the way headlines are written. Sentence case capitalises only the first letter of each sentence and lowercases the rest.
- Does Title Case skip small words like "of" and "the"?
- No. Every word gets a capital letter. Style guides disagree about which small words to skip, so this keeps the rule simple and predictable.
- Can I undo a change?
- Yes. Press Ctrl+Z (Cmd+Z on a Mac) inside the text box and your browser will step back, just like in any other text field.
- Is my text sent anywhere?
- No. The conversion happens inside your browser. The text never reaches our server, so it is safe to use with private notes.
