Questions
How random is the shuffle?
The tool uses a Fisher-Yates shuffle algorithm seeded by the browser's cryptographic random number generator, giving each possible ordering an equal probability.
Does pressing Shuffle again give a different result?
Yes — each press generates a new independent shuffle, so you can keep hitting Shuffle until you are happy with the order.
Are any lines added, removed, or changed?
No. Only the order of lines changes. Every line from your original text appears exactly once in the result.
Is my text sent to a server?
No. The shuffle runs entirely in your browser. Your text never leaves your device.
