Draw a name at random from a list

Nearly every online draw uses the browser's ordinary random function, which is predictable. This one uses the system's cryptographic generator, with rejection, and it shows you the exact count of possible outcomes.

A pasted list, one name per line

Nothing will be sent: the list is read here, on your device, and it disappears with the tab.
Ctrl + Enter also runs the tool.

Your text never leaves your device

This tool works entirely inside your browser. What you type or paste here is sent nowhere, and nothing is kept once the tab is closed.

Checkable in ten seconds, without taking our word for it:

  1. Open your browser's inspector: the F12 key (or Ctrl+Shift+I, or Cmd+Option+I on a Mac).
  2. Go to the “Network” tab, then clear the list.
  3. Type or paste some text on this page and run the tool. The list stays empty: no request goes out.
  4. To go further: cut your connection and do it again. The tool still works.

This absence of requests is also checked BY MACHINE before every release: a lock drives a real browser, processes a real file, and refuses to publish if a single byte goes out.

InstructionsHow it works

One name per line. Empty lines and stray spaces are stripped; duplicates are KEPT and reported, because two people can share a first name and quietly removing one would change your list without telling you.
