Does it support regular expressions and capture groups?

Yes. Enable Regex to treat the find field as a JavaScript regular expression, and reference capture groups in the replacement with $1, $2, or $ .

How do I replace whole words only?

With Regex off, tick "Whole word" — the search is wrapped in word boundaries so it ignores matches inside longer words.

Is my text uploaded anywhere?

No. All matching and replacing happens locally in your browser, so your text never leaves your device.

Find & Replace (Regex)

Find and replace text in bulk, right in your browser. Use a plain search or a full regular expression with capture groups, toggle case-insensitive, whole-word, and multiline matching, and see a live match count with a highlighted preview before you copy the result.

How to use Find & Replace (Regex)

Paste your text and enter what to find and what to replace it with.
Turn on Regex for pattern matching and $1 capture groups, or use whole-word for plain search.
Check the highlighted preview and match count, then copy the result.
