A find-and-replace across a whole document, with optional whole-word matching and full regular expression support - for anywhere a text editor's built-in version is too limited, or where the text itself is too sensitive to paste into an online editor you don't control.

When you'd use this

Bulk-renaming a repeated value across a large config or data file, cleaning up formatting inconsistencies across a document, or running a regex pattern to catch variations a plain text match would miss.

Common errors

A regex pattern that matches nothing usually has an unescaped special character - parentheses, periods, and brackets all mean something specific in regex syntax and need to be escaped (\., \(, \)) to match them literally.

Whole-word matching won't catch a term that's part of a hyphenated or punctuated compound (like matching "cat" inside "cat-food") - that's the boundary rule working as intended, not a bug, since "word boundary" has a specific technical meaning that doesn't always match intuition.
