Common questions
What limitations apply?
Line equality follows the selected case option. Retained lines keep their original text. Original order keeps the positions of retained occurrences.
Is my input saved?
No. It stays in browser memory and clears on refresh. Successful actions record only a stable tool ID and name, never your entered data.
