  1. 1Type or paste your text into the “Comments or names, one per line” box. There is already an example in it so you can see how it works; press Clear to start with your own.
  2. 2Choose your settings: “How many winners”, “Seed (leave blank for a new random one)”, “One entry per person”, “Exclude (your own @, staff)”.
  3. 3The answer appears right away in the “Result” box. No button needed.
  4. 4Press Copy and paste the result wherever you need it.

Words to know

Seed (fair draw)
A starting code for the random draw. Same list + same seed = same winners, so anyone can check the draw was fair.
Random
Chosen by chance so every option has an equal, unpredictable chance of being picked.
Hash / fingerprint (SHA-256)
A short code calculated from a file or text. Change even one letter and the code becomes completely different, so it proves nothing was altered.
Array / list
An ordered collection of items, like ["apple", "banana"]. Every programming language has one.
SHA-1 / SHA-256 fingerprint
A short code that identifies the key used to sign your app. Firebase, Google Sign-In and Maps ask for it to make sure requests come from your real app.
