Synastry
Two charts and two profiles, compared honestly.
What it is
Synastry is the practice of comparing two natal charts to explore the dynamics between two people. Cosmic Dossier extends the idea beyond astrology alone, comparing MBTI, Enneagram, attachment style and Big Five between two people as well.
A little history
Astrological synastry dates back to Hellenistic astrology, where comparing two charts was used to advise on marriages and alliances. Comparing psychological personality types between partners is a much more modern addition.
How Cosmic Dossier uses it
Add a second person's details on the input page to unlock a synastry report comparing emotional compatibility, communication, conflict style and attachment dynamics across every system in your dossier, not just the astrological chart.
Good to know
No compatibility system, astrological or psychological, can reliably predict relationship success. Synastry here is meant to surface real patterns worth talking through with a partner, not a score to accept or reject a relationship over.
