The Compatibility Check is a 25-item self-report tool that measures how your preferences, rhythms, and values align with a specific person in your life. Taking about 10–15 minutes, it maps your alignment across five practical dimensions: Values Alignment, Communication Fit, Energy Match, Lifestyle Harmony, and Conflict Handling. This assessment does not predict relationship success or generate a 'soulmate score'—research consistently shows that the ability to adapt to differences matters far more than having identical personalities. Instead, it provides a clear, neutral map of where your lives naturally synchronize and where you will need to actively negotiate and adapt.

The Compatibility Check avoids the common trap of 'personality matching.' Decades of relationship science indicate that similar personalities do not guarantee success, and differing personalities do not guarantee failure. What matters is the functional alignment of daily life and the shared skills for managing the inevitable gaps.
We measure compatibility where it actually impacts daily life. Values Alignment looks at ethics, priorities, and what you consider meaningful. Communication Fit assesses how reliably you understand each other. Energy Match compares your baseline pace and stimulation needs. Lifestyle Harmony evaluates the concrete habits of home, money, and socializing. Conflict Handling measures how safely and effectively you move through disagreement.
Popular culture assumes that the goal of dating is finding someone exactly like you. However, relationship research (including work by Gottman and others) shows that the amount of conflict in a relationship is less predictive of divorce than *how* that conflict is managed. You can have low natural Lifestyle Harmony but high relationship satisfaction if both partners have strong Conflict Handling and Repair skills. This tool highlights where you match natively, and where you must rely on those skills.

No two people are perfectly compatible. In every long-term relationship, there are perpetual, unresolvable differences. The goal is not to find a relationship with no gaps, but to find one where the gaps are manageable and the differences are treated with respect rather than contempt. The Compatibility Check helps you name those gaps early, so you can build the adaptation strategies necessary to bridge them.
Absolutely not. This tool does not predict relationship success or issue "soulmate scores." A low alignment score simply means your natural preferences differ significantly. Many successful couples have profound differences; they succeed because they have built excellent communication and adaptation skills. A low score tells you *where* you need to work, not *whether* the relationship can work.
While all dimensions matter, research suggests that Values Alignment and Conflict Handling are often the most critical load-bearing pillars. You can compromise on Lifestyle Harmony (e.g., one person is messy, the other is tidy), but it is very difficult to compromise on core ethical values or to survive a relationship where conflict is handled with contempt or stonewalling.
Energy Match is one of the most underrated aspects of daily compatibility. If one person recharges through high-stimulation social events (high energy output) and the other requires quiet, low-stimulation downtime (low energy output), weekend planning will be a constant negotiation. Naming this as an "energy difference" rather than "you're boring" or "you're exhausting" depersonalizes the friction.
Yes. Lifestyle Harmony and Communication Fit often improve over time as couples learn each other's rhythms and build shared habits. Conversely, Values Alignment can shift—and sometimes diverge—as people grow, age, and undergo major life transitions. Compatibility is a dynamic state, not a fixed trait.
High alignment makes daily life smoother, but it doesn't eliminate problems. Sometimes, couples who are highly similar avoid conflict because they assume they should naturally agree on everything, leaving them unpracticed when a real disagreement finally arises. High alignment is a great foundation, but you still need active relationship skills.
It can be a useful conversation starter, but be cautious: in the early stages of dating, the "halo effect" often makes us perceive more similarity than actually exists. The tool is generally more accurate after you have navigated at least a few minor conflicts and seen each other in different contexts.
Personality tests (like the Big Five or Enneagram) measure who you are in isolation. The Compatibility Check measures the specific friction and flow between your preferences and another person's behavior in practical, real-world domains.
Your Compatibility Check provides a detailed map of your relational alignment, identifying natural flow states and areas requiring active negotiation.
