MatchMyType is a free MBTI compatibility site. Choose your type and another person's type to get compatibility scores for love, work and friendship, plus a long-form analysis of how the two types communicate, where they clash and how to make it work. Each type also has a ranking of its best and most challenging matches. Pages are in English, Japanese and Korean, and no account is needed to read them. A 16-type personality test is also available: the basic result is free and a full report is an optional paid upgrade.
