工作原理

  1. Paste. Put any list in the box, one item per line.
  2. Pick. Hit Randomize. You can re-roll any time.
  3. Track. Turn on "No repeats" to make sure the same item isn't picked twice this session.

常见问题

How is the pick chosen?

Each item has exactly equal probability. We pick a uniformly-random index using the Web Crypto API (crypto.getRandomValues) with rejection sampling, so there's no modulo bias.

Can it avoid repeats?

Turn on "No repeats" in Options and previously-picked items will be skipped until you reset, which is great for working through a list one winner at a time.

Does my list get sent anywhere?

No. Everything runs entirely in your browser, your list is never uploaded, and the tool keeps working even offline.
