A test for a couple · both take it
Compatibility test for two
You each answer the same questions about the same relationship, separately. Then we show where your pictures agree, where you see the same thing differently — and what to do about it.

This is what one question looks like
The questions are plain and about an ordinary week, not about an ideal relationship. Answer as things actually are — your partner will never see your answers, only the shared read.
Move the slider and watch an answer turn into a position on a scale. The real test computes it the same way: arithmetic, not an AI opinion.
Appreciation
Answer about how things actually are lately. “Not at all” is as valid an answer as any other.
The real test has 62 such items across thirteen facets, and the uncertainty band is noticeably narrower. And above all — your partner fills in the same facet, and the product begins where the two pictures diverge.
Why together
This result does not exist for one person
A large study across 43 datasets and 11,196 couples found something unexpected: how well partners “match” on personality has almost nothing to do with how satisfied they are. A partner’s traits explain about 5% of your satisfaction. What does predict a relationship is of a different kind — how sure you are that your partner stays, whether they notice what you do, how intimacy sits with you, how arguments go.
All of that is perception. And perception cannot be measured by one person: both have to answer about the same thing before it becomes visible where the pictures diverge. So we do not compute a “compatibility percentage” — we have no such number and never will, it would be an invention. We show a map of divergences.

What we measure
Two axes and thirteen facets
Connection and strain are computed separately: a couple can be very warm and very strained at once, and a single number would collapse those two pictures into one.
Appreciation
Appreciation
Whether you see what the other does, and whether you feel seen. One of the strongest things linked to relationship quality at all.
Facets inside
- Appreciation
Ends of the scale taken for granted — genuinely noticed
Perceived commitment
Perceived commitment
How sure you are that your partner is there, including when it is hard. Not about promises — about the ground under your feet.
Facets inside
- Perceived commitment
Ends of the scale have to keep checking — no doubt
Intimacy
Intimacy
Whether you are content with how intimacy works and whether your expectations meet. We never ask how often: frequency says nothing about quality.
Facets inside
- Intimacy
Ends of the scale I go along — I am content
Talking and support
Talking and support
Whether conversations beyond logistics survived and whether you get through hard things together. This also catches the opposite — when there is no one to lean on but each other.
Facets inside
- Talking
- Support under stress
- Being seen whole
Ends of the scale each on their own — together
Conflict and repair
Conflict and repair
Whether arguments start sharply and whether you can stop and come back. Repairing matters more than not arguing.
Facets inside
- Conflict and repair
Ends of the scale we store it up — we repair fast
The unsaid
The unsaid
How many topics you walk around so as not to start. The most common finding — and almost always shared by both.
Facets inside
- The unsaid
Ends of the scale we say it right away — we walk around it
Load and agreements
Load and agreements
Whether the load feels fair to you and whether there are clear agreements that hold. Not about roles and not about who is in charge.
Facets inside
- Fairness of load
- Agreements
Ends of the scale each our own way — we agreed
Space and people around
Space and people around
Whether each of you has room of your own and whether anyone around is glad for you. Having no outside support is a real load, not a detail.
Facets inside
- Room of one’s own
- Support from outside
- Safety
Ends of the scale cramped and alone — air and support
How we compute
The numbers are computed by an algorithm, not by AI
- Step 1
Answers are unfolded
Reversed items are flipped so that “agree” means the same thing everywhere.
- Step 2
A facet is assembled
Each facet is the average of its items, mapped onto a 0 to 100 scale.
- Step 3
The divergence is computed
Once both sides have answered, each facet takes the distance between the two positions, multiplied by how much it weighs.
- Step 4
AI explains finished numbers
The model receives what is already computed and may never name a different figure.
Why there is no compatibility percentage
Because research showed that partner matching on traits is almost unrelated to relationship satisfaction. Such a number would look convincing and mean nothing.
How it goes
Tests for couples: step by step
The online compatibility test is taken on a phone or a computer, each of you on your own. The second person pays nothing and figures out nothing: they open a link and answer.
- 1
You take the test
About 13 minutes, 62 questions. Right after, we show your half of the map for free.
- 2
You pay once
One payment for both. You get your own full read immediately — no waiting for your partner.
- 3
You send the link
Your partner opens it and takes the same test. For them it is already paid for.
- 4
The shared read arrives
When they finish, the map of divergences appears for both of you. We will email you — no need to keep a tab open.
What you get
Three documents, not one
A compatibility test for partners produces three documents: your read, your partner’s read, and the shared one — the reason all of this exists.
Free, right after the test
- Your point on the two-axis map and the name of the area
- Positions on both axes — connection and strain
- If the answers carry fear or coercion, you see it for free
In the full read
- Your own read: thirteen facets and what sits behind them
- Your partner’s own read, separate from yours
- The map of divergences: where you see it differently and what matters
- Where you agree — both upward and downward
- Your blind spots: what you assumed against what they reported
- Concrete conversations with an opening line you could say out loud
- A PDF of the full read — one for each of you
One payment for both. The partner link lasts as long as the read itself — it never expires.
What it rests on
What sits behind this
This is a psychological compatibility test, not a quiz: we wrote our own questionnaire, and from known instruments we took only the structure of the construct — reproducing someone else’s items is not allowed, and not needed.

datasets in the work on predictors of relationship quality
62

What predicts a relationship
Perceived partner commitment, appreciation, satisfaction with intimacy, conflict. These are our axes.
The perception layer
Each of you predicts how the other will answer. The gap between prediction and reality is what a single-person test cannot give at all.
One questionnaire for any couple
A measure invariant across gender and orientation exists and has been tested. We ask nothing that does not affect the score.
What the test does not do. The test has no normative sample: a position of 0–100 is how pronounced something is in your answers, not a comparison with other couples. The thresholds are ours. The test makes no diagnosis, does not grade you as a couple and does not tell you what to do about your relationship.
Who it fits
A couple compatibility test — who it is for
Those for whom everything is “fine”
When there is no obvious problem but conversations have narrowed to logistics. This is exactly where divergences usually turn up.
Those together a long time
When it feels like you know everything about each other. Blind spots are the most common finding in long relationships.
Those moving in or planning
Before agreements have to be worked out on the fly.
Those arguing in circles
When the same argument repeats and the reason looks new every time.
About the service
Who makes this
LabReadAI is an information service. We explain data; decisions stay with people.
When one person answers questions about a couple, only their point of view is measured — and everyone has their own, which is fine. The interesting part begins where the two of you describe the same thing differently without suspecting it. That divergence cannot be computed from one set of answers; it can only be seen by putting two pictures side by side.
- Each answers separately and never sees the other’s answers — otherwise the second one adjusts and there is nothing left to measure;
- The same 62 questions for both: a divergence is computed only across identical items;
- Five facets are filled in twice by each — for themselves, and as a prediction of the partner;
- A missed prediction is a blind spot: something a single-person test cannot give at all.
A number like “you are 78% compatible” looks convincing and means nothing. Relationship research consistently shows that how similar or well-matched partners are on traits barely predicts whether they will be satisfied. What predicts it are perceptions inside the relationship — and those differ between the two. So instead of one figure we show a map: where your pictures agree, where they part, and how much that divergence weighs.
- No verdict that you do or do not suit each other — it cannot be derived honestly;
- No predictions about whether the relationship lasts: the test describes now, not the future;
- Agreeing downward is a finding too: if both say something is thin, there is nothing to argue about;
- The order of the read is set by weights computed in code, not by what sounds more interesting.
Connection and strain are computed separately because they are independent. A couple can be very warm and very strained at the same time — and that is not the same as warm and calm. A single number would collapse both pictures into one and hide exactly what people come for.
- The connection axis: appreciation, perceived commitment, talking, intimacy, support under stress, being seen whole;
- The strain axis: conflict and repair, the unsaid, fairness of load, agreements, room of one’s own, outside support, safety;
- The point lands in one of four areas — that is the name of a REGION, not a grade for the couple;
- Intimacy is measured by satisfaction and matching expectations, never by frequency: frequency says nothing about quality.
You get your own full read immediately — no waiting for your partner. A link appears with it: your partner opens it and takes the same test, already paid for. When they finish, the shared map of divergences appears for both of you, and we send an email — no need to keep a tab open.
- Three documents: your read, your partner’s read, and the shared one;
- The link never expires: send it whenever, and if your partner never comes, your read stays with you;
- A PDF for both and an AI chat about your own read;
- If the answers carry fear, control or coercion, you see it for free, before paying.
Ten of the sixty-two items are predictions: you answer not about yourself but about how you believe the other one will answer. While your partner stays silent this is simply a picture of your expectations. The moment they answer, the prediction gains something to be checked against — and the miss between “I thought they were fine here” and their own answer is a blind spot. Alone it cannot be found at any number of questions: there is nothing to compare it to.
A blind spot is not a fault and not carelessness. Research on perception in couples shows that people systematically see a partner through their own expectations, and that holds for everyone, including couples of many years. That is why a missed prediction gets its own block in the read instead of dissolving into general talk about misunderstanding.
- Each of you predicts five of the partner’s facets — the ones where a miss costs the most;
- A prediction is never passed off as a fact about the partner: until they answer it is an expectation, and it is labelled as one;
- Only YOUR blind spot is shown: your partner reads their own misses in their own copy;
- A prediction that lands is a result too: it means you genuinely see each other.
A divergence is not an argument to be won, and not a mistake by one of you. Both positions are read from the answers honestly: the same week simply feels different to each of you. So the read passes no verdict on who is closer to the truth; instead it gives what actually resolves a divergence — a concrete conversation with a ready first sentence you can say out loud without opening with an accusation.
The order of the conversations is set by weights computed in code, not by what sounds more dramatic: the facets where the gap is wider and the weight higher come first. Agreements are not thrown away either — if you both say something is missing, there is nothing to argue about, and that is the easiest thing to bring back.
- The first sentence of a conversation is yours, not ours: it can be repeated word for word;
- Not a single task for the partner: the read is written to you and talks about what you can do;
- Where the picture points at something a conversation cannot resolve, the role of a specialist is named — no brands, no scare;
- No rating for the couple and no prediction about whether you last: the test describes now.
Questions
Questions about the test
Briefly, about what gets asked most.
No, never. They receive only the shared read, which compares pictures rather than individual answers. This is not politeness but a condition of the test working: if answers were visible, the second person would answer to match, and the divergences — the whole point — would not exist.
Free, you get your half of the map right after taking it: positions on both axes, your point with the name of the area, and — always — a warning if the answers carry fear or coercion. The full read for two costs 1750 ₽, paid once, and includes your read, your partner’s read and the shared map of divergences.
No. One payment covers both and is made by whoever goes first. The second person opens a link and their test is already paid for — no money, no card.
Your full read stays with you: you get it right after payment and do not depend on your partner. The link never expires — it can be sent later or resent a year from now.
Yes. We ask nothing that does not affect the score: the questions are written to read the same way for any two people, and the composition of the couple is never discussed in the read — research shows the predictors of relationship quality are the same.
No. It is an educational tool: our own questionnaire built on measures that relationship research links to relationship quality. It makes no diagnosis, does not grade you as a couple and does not tell you what to do. The test has no normative sample — a position of 0–100 shows how pronounced something is in your answers, not a comparison with other couples.
About 13 minutes per person, 62 questions. Answers are saved as you go, so you can close the tab and come back.

The test is not a medical service, not psychodiagnostics and not a verdict on your relationship. It computes no compatibility percentage and predicts nothing about whether the relationship lasts. If the answers carry fear, control or coercion, that is a reason to seek help.
