You can take the Myers-Briggs Type Indicator (MBTI) test online for free, although many of the free versions are unofficial and less detailed than the official assessment. These tests can still provide you with useful insights into your personality type, which you can then use to explore compatibility with your partner.

Where to Get Free Myers-Briggs Compatibility Tests:

1. 16Personalities:

   • One of the most popular free versions of the MBTI is available at 16Personalities. This website offers a comprehensive and user-friendly version of the test, with a detailed breakdown of your personality type and how it affects various aspects of life, including relationships.
   • After both you and your partner take the test, you can compare your personality types and explore how they interact.

2. Truity:

   • Another free test is offered by Truity. It provides a similar experience to the MBTI and offers a relationship section that can help you understand compatibility between different personality types.

3. Personality Max:

   • Personality Max offers a free MBTI-based test that breaks down not only your personality type but also other aspects like communication style, career preferences, and relationship compatibility.

Paid Option:

• The official MBTI test is available through the Myers-Briggs Foundation, but it comes with a fee (usually around $50). This version is more detailed and often used by relationship professionals for deeper personality and compatibility assessments.
