About
Find & Replace searches text with either a literal string or a full regular expression, supporting case sensitivity, whole-word matching, and capture-group references like $1 in the replacement. Matches are highlighted inline as you type the search term, before you commit to replacing anything. All processing happens in your browser — the text you search never leaves your device.
Frequently asked
- Does it support regex capture groups in the replacement?
- Yes — replacement text can reference capture groups with $1, $2, and so on, the same syntax JavaScript's replace() uses.
- Can I preview matches before replacing them?
- Yes, matches are highlighted inline in the text as you type, so you can check what will change before running the replace.
