About Text Shuffle
The Multi-Mode Text, Word & Line Randomizer Shuffler randomizes the order of lines, individual words, sentences, or characters using the cryptographically secure Fisher-Yates shuffle algorithm with seed reproducibility.
How to Use Text Shuffle
Step 1
Paste your text or list into the input box.
Step 2
Select shuffle mode (Lines, Words, or Characters).
Step 3
Click "Shuffle" (or tap Spacebar to re-shuffle).
Step 4
Click "Copy Shuffled Text".
Practical Use Cases for Text Shuffle
Randomizing Quiz Questions & Flashcards
Shuffle lists of vocabulary words, study flashcards, and test question options to prevent order memorization.
Contest Giveaways & Randomized Prize Drawings
Randomize participant list entries fairly for raffle drawings and tournament bracket seeding.
Input & Output Examples
Shuffling List of 4 Items
Lines:\nApple\nBanana\nCherry\nDate
Shuffled Lines:\nCherry\nDate\nApple\nBanana (Algorithm: Fisher-Yates | Uniform Probability)

Key Terminology & Definitions
Fisher-Yates (Knuth) Shuffle
An unbiased algorithm for generating a random permutation of a finite sequence in $O(n)$ linear time, ensuring every permutation has equal probability.
Cryptographic Randomness
Using hardware entropy sources via Web Crypto API to ensure unpredictable, statistically uniform randomization.
