A nemesis is someone who has a better official rank than you in every event you have officially participated in (both average and single). This site uses data from the WCA database to find nemeses for people. It is not officially affiliated with the WCA.
If you find a bug or have a feature request, please email it to bugs at nemesizer. At some point, there'll be a proper bug reporting facility here.
