Overview

Inspired by science, "synthesize" recolors numbers and letters on webpages to induce synesthesia in the user!

By default, it runs on all websites, but you can add/remove any website you want. This extension was made with the methodologies of Bor et al. (2014) in mind, where a team of scientists found that by having adults read colored text, they could induce learned grapheme-color synthesia in them, which resultingly increased their IQ by an average of 12 points. In addition to coloring text on webpages, Synthesize has a "passive drill" option that follows the exact methodology of one of the drills Bor et al. used to train synthesia in subjects. In the study itself, this specific drill is given 20 times per training session for one week. Expect regular updates and features added. Support responses will be prompt and user feature recommendations will be followed. Email jeremykalfus [at] gmail.com or use support feature for discussions, comments, sugguestions, or support.
