I'm Justin, creator of -- a free and open-sourced tool to help chess players memorize opening repertoires.

I built because I wanted a tool like this for my own tournament prep and figured other chess players out there might also find it useful. Note that I'm just a hobbyist chess player; professionally, I'm a software engineer, and maintaining this site is just a fun side hobby for me. will always be free and open-sourced, although it isn't free to maintain it. I pay all of the server/maintenance costs out of pocket, but any support from patrons would be very much appreciated. Whether you decide to support or not, I really appreciate any feedback, positive or negative, about the site.

Happy studying!
