Name compatibility calculator
Score how well two names match, with the working shown step by step.
Name compatibility calculator
Paste two names and this tool works out a compatibility percentage from the letters they share, showing every intermediate step rather than just a final number. It is a text-based party trick more than a science, and it is a fun way to check name pairs, test screen names, or settle a friendly argument about who a nickname secretly points to.
Two calculation methods are available. "Matching letters" cancels out the letters two names have in common, the way the paper elimination game works, then reduces whatever letters are left into a percentage through repeated digit addition. "Classic letter game" is the well-known trick of writing both names together and counting how many L, O, V and E letters turn up, then reducing that count the same way. Switch "Include surnames" on to compare full names instead of just first names, and turn "Ignore diacritics and spaces" off if you want accented letters such as š or ü treated as distinct from their plain equivalents. "Add a short comment" appends one line summarizing the score, and "Output language" lets you keep that summary in English even when the site itself is set to another language.
Paste one pair per line — separated by a comma, an ampersand, "vs" or "and" — to score a whole list at once, which is handy for running several couples or nicknames through the same settings in one pass. A line that doesn't contain exactly two names is skipped and counted separately rather than guessed at, and the tally under the output reports how many pairs were scored and the average result.
