About Find & Replace

What this does

Find and replace text with (or without) regular expressions. The match count updates live, matches are highlighted in a preview panel, and you can either apply the change back to the input or copy just the result. All four common regex flags are one-click toggles: case-insensitive (i), multiline (m), dot-all (s), and global (always on).

Handy for

Renaming a placeholder across a document
Applying a regex extraction to a log paste
Cleaning up scraped text with consistent patterns
Testing a regex before pasting it into your code
