Find & Replace

Find & Replace searches a block of text for a word or pattern and swaps every match — or just the first one — for something else, with optional case sensitivity and a full regex mode for pattern-based replacements. It's a plain-text-editor superpower without needing to open one: paste, search, replace, copy.

It's used for fixing a misspelled name repeated throughout a document, updating an old URL or domain across pasted content before republishing, standardizing terminology in a style guide pass (replacing every 'e-mail' with 'email', for instance), and — in regex mode — restructuring formatted data, like turning every 'YYYY-MM-DD' date into 'DD/MM/YYYY' using capture groups. The live match counter shows exactly how many replacements will happen before you commit to them, so a find pattern that's broader than intended is obvious immediately rather than discovered after the fact.

Regex mode unlocks capture groups and pattern matching: search for `(\d+)-(\d+)-(\d+)` and replace with `$3/$2/$1` to reorder date components, or use character classes and quantifiers to match variable-length patterns a literal find can't. In plain-text mode (the default), the find field is treated as an exact literal string — special regex characters like `.` or `(` are automatically escaped, so searching for a literal period or parenthesis just works without needing to know regex syntax at all.

'Replace all occurrences' controls whether every match is replaced or only the first one found; case sensitivity controls whether 'Email' and 'email' are treated as the same search term. All matching and replacement happens instantly in your browser as you type, with invalid regex patterns caught and reported inline rather than silently failing.
