What shuffle algorithm is used?

The tool uses the Fisher-Yates (also called Knuth) shuffle, which produces a uniformly random permutation. Each element has an equal probability of landing in any position.

Is my text sent to a server?

No. All processing runs entirely in your browser using JavaScript. Your text is never transmitted anywhere.

What is the difference between the three modes?

Character mode rearranges every individual character in the text. Word mode treats whitespace-separated tokens as units and shuffles those. Line mode treats each newline-separated line as a unit and shuffles those.

Can I shuffle multiple times?

Yes. The Shuffle button applies a fresh randomization every time you click it. Each click produces an independent, unpredictable result.

Does it preserve blank lines in Line mode?

Yes. Blank lines are treated as empty-string entries and included in the shuffle just like any other line, so the total line count stays the same.
