About Nemesizer

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.

Current known bugs and planned features:
  • Paging of results
  • Error handling
  • Show which events people beat me in, and by how much
  • Show which events I beat people in
  • Show me what I need to do to stop person X from nemesizing me
  • Bug reporting button
  • Bug: doesn't handle people who only have DNFs very well
  • Filter by gender
  • Improve mobile experience
  • Nemesis alerts: email me when I gain / lose a nemesis
  • Country nemeses DONE
  • Countries nemesized by people (and vice versa) DONE
  • Autocomplete of WCA IDs and names DONE
  • Who gets closest to nemesizing me if I have no nemeses? DONE. (To see this working, try searching for nemeses for someone that you know has no nemeses. Or go to stats and look at the people with the fewest nemeses).
