Find and Replace Tool

What is Find & Replace?

The Find and Replace tool performs bulk search-and-replace across pasted text without opening a full text editor — supporting plain-text, case-sensitive, whole-word and regular-expression matching, with a live match count.

How it works

The find term is compiled into a RegExp (escaped when not in regex mode, wrapped in word boundaries for whole-word mode). The live match count updates as you type, and Replace All / Replace Next rewrite the document in place. Regex capture groups like $1 work in the replacement string.

1. Paste your document. Any block of text — a chat export, PDF-extracted text, a draft, or config content.
2. Enter find and replace terms. The match count updates live. Toggle case sensitivity, whole-word or regex mode as needed.
3. Replace. Replace All rewrites every match; Replace Next steps through one at a time. Copy the result when done.

Examples

Fix a recurring typo

Replace every instance of 'teh' with 'the' across a long pasted document in one click.

Regex with capture groups

Replace pattern (\d{4}) with '$1-' to reformat year groups, using $1 to reuse the captured digits.

Common mistakes

Regex metacharacters in plain mode

Plain-text mode escapes regex characters automatically — a literal 'a.b' matches 'a.b', not 'aXb'.

Invalid regex patterns

A malformed pattern (e.g. an unmatched '(') shows a clear error instead of silently failing.
