Now live at socion.app Socionics maps 16 named relationship dynamics between every personality type — not just compatible or incompatible, but characterised dynamics each with a predictable pattern. This app puts that theory in your hands.Match by personality,
not algorithm.
How it works Work through a structured onboarding questionnaire. Bring an existing type from the community if you have one — confidence scoring means we handle uncertainty honestly. Select which intertype relations you’re open to. Duals for deep complementarity. Mirrors for intellectual sparring. You set the terms — the app surfaces who fits. Dating, friendship, networking, and team building. The same theory applies across all contexts — a Dual is a Dual whether you’re dating or building a product team.You choose the dynamic.
Not a black-box algorithm.Determine your type

Match with purpose
Developed in the 1970s on Jungian foundations, Socionics maps 16 specific dynamics between every type pair. This app is built for the English-language Socionics community — and designed to generate real data on whether the theory holds at scale.“Unlike MBTI or the Big Five, Socionics is primarily a theory of intertype relations. The unit of analysis is the dyad, not the person.”
Why different Most matching products optimise for engagement, not compatibility. Socion is built on Socionics — a framework with 16 named, characterised relationship dynamics. You can inspect the logic. You can choose the dynamic. The theory makes testable predictions, and the app is designed to test them. Rather than delegating compatibility to a proprietary algorithm, you select which intertype relation you're looking for — Dual, Mirror, Activity, or any of the 16 named dynamics. The intertype relations matrix is published and auditable. You know exactly why you're being matched with someone — not because a model decided you'd engage with each other. Self-report is unreliable. Socion uses a probability distribution across likely types rather than a single assignment — and refines it over time based on behavioural signals. Post-match feedback feeds back into type confidence scoring and generates empirical data on relation type outcomes. The app is designed to validate — or challenge — the theory at scale.An explicit theory.
Not a black box.
Built for more than dating Socionics doesn't distinguish between romantic and professional compatibility — a Dual is a Dual whether you're dating or building a product team. The data model is purpose-agnostic from day one. Find someone whose type creates natural complementarity — not just shared interests. Meet people whose type creates natural rapport and easy energy. Find collaborators whose type complements yours professionally. Assemble groups with intentional type diversity or complementarity.One theory.
Every context.
The data opportunity Socionics makes specific, falsifiable predictions about relationship quality across romantic, professional, and social contexts. Socion is among the first large-scale empirical tests of those predictions in the English-speaking world. Post-match feedback and conversation data will generate a dataset no one else has — not a self-report survey, but revealed behaviour across thousands of real interactions.Real-world evidence

The intertype relations matrix and matching code are open source. Community trust through transparency — not a black box. The hosted service, brand, and accumulated data remain proprietary.The matching logic is public
