It works entirely in the browser, so you do not need to install anything or open a large document editor. It is quicker for plain text jobs, supports regex and live previews, and keeps data on your device. Desktop tools still win when you must preserve complex formatting.
Enable the regex toggle, then use familiar patterns such as \\d for numbers, \\s for whitespace, and capture groups like (pattern) with replacements that reference $1, $2, and so on. Test on a short sample before applying to large text.
Yes. Leave the replacement field empty to delete any matches. This is handy for removing unwanted phrases, stray punctuation, or duplicate whitespace.
No. Everything happens within your browser session. Once you close the page the data disappears, making the tool safe for drafts, proprietary code, or customer information.
Because the processing happens in memory, the tool comfortably handles documents with tens of thousands of words. Extremely large inputs may take longer depending on your device, so try breaking work into sections if performance drops.
When regex is disabled you can type characters exactly as they appear. With regex enabled you should escape special tokens using a backslash, for example \\? to match a question mark.
Keep a small snippet library in your notes app or version control. Because everything is text based, you can paste known-good patterns and replacements whenever you revisit similar jobs.
Yes. The layout is responsive and supports mobile copy and paste gestures, so you can clean up text while away from your main workstation.
