Frequently asked questions

Can I use regular expressions in Find & Replace?
Yes. Toggle the "Regular expressions" option to use standard JavaScript Regex patterns, including character classes, quantifiers, and capture groups ($1, $2).
What does "Match whole words only" do?
It wraps your search term in word boundaries (), ensuring words like "cat" are replaced without affecting words like "catalog" or "caterpillar".
Can I leave the replacement box empty to delete text?
Yes. If the "Replace with" box is empty, every matching instance will be stripped and removed from the text.
How many characters or words can I process?
Because processing runs on your local computer via browser memory, you can easily process tens of thousands of words and large logs without lag.
Is my text stored on any server?
No. Everything is calculated in memory inside your browser. No text data ever leaves your device.
