About

Type items one per line, optionally with a weight (Coffee: 3). The tool picks one at random where the chance is proportional to the weight. Tracks how often each option has been picked.

How to use

  1. List items with weights.
  2. Hit pick.

FAQ

What if I don't add weights?+

Items without weights default to 1. So 'Coffee' (no weight) is equally likely as 'Tea: 1' and half as likely as 'Coffee: 2'.
