よくある質問

Can I use regular expressions?

Yes. Toggle 'Regex mode' to interpret the find pattern as a JavaScript regex. Use $1, $2 in the replacement for capture groups.

Is find case-sensitive by default?

Yes. Toggle 'Ignore case' to match regardless of case.

How do I replace only the first occurrence?

Turn off 'Replace all' - only the first match is replaced. Global replacement (all matches) is the default.

Is my text uploaded?

No. All matching and replacement happens locally via the browser's native string and RegExp APIs.
