Master Key

This is the site dedicated to helping anyone identify anything. We don't have very much to offer yet, but if you understand dichotomy, we'd love your help building this tool!



Welcome to the MasterKey Wiki
A dichotomous key to everything, built by everyone.

'''If you understand dichotomy, please help! DO NOT copy text from existing keys! If adapting from an existing one, please be sure to list it as a reference on that page!

''Keep in mind our audience is the world-- write in a manner that the layperson can understand with minimal additional research! When possible, use "macro" differences that are easy to spot from a distance on a living specimen, keeping in mind not all people have caught their specimen and not all have access to magnification.

 * WhatBird - A very powerful polychotomous key for identifying a bird you have seen.
 * Identifont - featuring a polychotomous key for identifying a font
 * Akinator - Not so much a key as it is a game, but you could use it as a key! Dichotomous questions to identify a person, fictional or real.
