WhatCharacter started as a way to track the interconnections of different literary (and film) characters. It was originally intended to be an analog system involving a repurposed card catalog system, but, like many of the things we do, grew in complexity until making it a website made far more sense.
This site aims to present a catalog of literary characters (for some definition of the word literary) and related elements, such as their appearances across different media (book, film, television, video games, etc.) as how different characters are related to one another.
In addition, this catalog of data allows us to look deeper into the works to provide "holistic" recommendations (that is, recommendations that do not take into consideration what other people like, but instead, those things that make the work "interesting" to you, whether or not you realize it).
