About Compatibility Hub

Our Passion

Compatibility Hub started as a personal passion project. We're a small group of developers and designers who share a deep interest in astrology, moon phases, and personality psychology.

We wanted to explore how these ancient traditions could be combined with modern AI technology to create unique, insightful compatibility analyses. Our goal is to provide fun, thought-provoking insights that help people understand themselves and their relationships better.

What We Offer

We offer eight free personality and relationship tools; optional AI analysis adds another perspective:

  • MBTI - Personality type compatibility based on Jungian psychology
  • Zodiac — Traditional astrological compatibility between sun signs
  • Moon Phase — Emotional compatibility based on birth moon phases
  • SBTI — A playful, internet-culture-inspired personality test
  • Love Language — How you give and receive love, based on Gary Chapman's five love languages
  • Attachment Style — Explore patterns of closeness, anxiety, and avoidance in relationships
  • Enneagram — Discover your core motivation, fears, and growth direction across 9 personality types
  • Big Five — Explore five broad personality traits with a public-domain IPIP measure

Our Promise

🆓 Forever Free

All our tests are completely free to use. No paywalls, no premium features, no hidden costs.

🔐 No Registration Required

You can use all our tests without creating an account or logging in. Your privacy matters to us.

🤖 AI Deep Dive

Scores come from a fixed scoring rule built on each framework. AI is the second layer — it explains why a result came out that way, and what you can change.

What's Next

We're always exploring new ideas! In the future, we'd love to add more cultural traditions to our compatibility toolbox, such as:

  • Chinese zodiac compatibility
  • Tarot-based relationship insights
  • I Ching divination for relationship guidance
  • Other forms of traditional divination and fortune-telling

These features are still in the planning stages, but we're excited to expand into different cultural perspectives on compatibility and relationships.
