Frequently Asked Questions
What is regex mode and when should I use it?
Regex mode treats your search term as a regular expression, letting you match patterns like digits, repeated characters, or text at the start of a line. Use it for advanced edits; leave it off for plain text replacements.
Does it replace every match or just the first one?
It replaces all matches in the text in a single pass and shows you the total number of replacements made.
How does case sensitivity work here?
With case-sensitive matching off, the search ignores letter case, so 'Color' and 'color' both match. Turn it on to match only the exact capitalization you typed.
Is my text sent anywhere?
No. The find-and-replace operation runs entirely in your browser using JavaScript, so your text remains private on your device.
