Prisamor is a relationship psychology platform offering free, research-based tests to help people understand their personalities, values, attachment patterns, and relationships. Its tools include the IPIP-NEO Big Five personality test, ECR-R attachment style test, LAS-42 love styles test, CSI-32 relationship satisfaction test, HISC couple compatibility test, and PVQ-21 personal values test. Users can complete tests individually and, by linking accounts with a partner, explore areas of compatibility and potential growth.

After a test, Prisamor provides AI-generated interpretations designed to put results in context, highlight individual traits, and offer practical suggestions for personal development and relationships. The platform says its instruments have been validated and reports reliability above 0.85, while noting that the tests are for self-discovery rather than medical diagnosis. Tests are free, with premium options for extended AI reports, deeper couple analytics, and progress history. Prisamor also describes privacy protections, including encryption and a commitment not to share data with third parties.
