Frequently asked questions
What is regex mode?
Regular expression mode lets you use patterns like \d+ (any number), [aeiou] (vowels), or ^Line (starts with "Line"). Capture groups (\1, \2) work in the replacement string.
How do I remove text (delete without replacing)?
Leave the "Replace with" field empty. All matches will be deleted from the text.
Is this safe for sensitive text?
Yes — all processing happens in your browser. Your text is never sent to a server.

How the find & replace works

No server-side processing means your data stays on your device. Results update in real time as you change inputs.
Plain text vs regex
Plain text mode is simpler and safer — it matches exactly what you type. Regex mode is powerful but requires knowledge of regex syntax. For simple substitutions, plain text is always the right choice. For patterns (like "replace all email addresses"), regex is necessary.
Common regex patterns
\d+ = one or more digits. \s+ = one or more whitespace characters. [A-Z] = any uppercase letter. .* = any sequence of characters. ^ = start of line, $ = end of line. Use these to find patterns rather than specific strings.
