What is the Find & Replace Tool?
Run multiple find-and-replace rules on a block of text at once, entirely in your browser. Add as many rules as you need — each one runs in order, so the output of one rule feeds into the next, letting you chain several transformations in a single pass instead of doing them one at a time.
Each rule can be toggled independently for case-sensitivity, whole-word-only matching, or full regex mode with capture-group support in the replacement (using $1, $2, etc.). A Diff Preview shows exactly what changed, word by word, before you copy or download the result.

Questions people ask
Can I run multiple rules at once?
Yes — add as many find/replace rules as you need; they run in order from top to bottom.
How does Regex mode work?
When Regex is checked for a rule, Find is treated as a JavaScript regular expression, and you can use capture groups like $1 in Replace.
What does Whole Word matching do?
It wraps your search term with word boundaries so it only matches complete words, not substrings inside longer words.
Is my text sent to a server?
No, all find-and-replace operations run entirely in your browser using JavaScript.
What is the Diff Preview?
A side-by-side, word-level comparison showing exactly what was added or removed before you finalize the result.
