Features

Unique service

Find relatives by photo

Find your relatives in photos by comparing faces, or determine that the same person appears in different photos — this can help restore family ties and learn more about your ancestry.

One of a kind

Paternity test by photo

Take a paternity test if you have doubts: compare the faces of your child and the presumed parent — but keep in mind this method is not yet as reliable as DNA testing.

Entertainment

Photo similarity

Test any faces for similarity; see who your child resembles more — the ways you can use the app are limited only by your imagination.

How it works

1

Get access

Make a payment and get access to the test, or choose a free test — it also helps you check whether your photos meet the requirements before you pay.

2

Select the required photos

Each photo must be no larger than 6 MB, contain one face, and meet the requirements (see below).

3

Press “Test”… and voilà

The magic starts here! Save or share your result, then run another test with different photos or different people.

Advantages

Simplicity

Our photo-based kinship service is easy to use and requires no special skills. To take the online test, you only need two photos — our AI processes them for you. No need to go anywhere or submit samples like with a DNA test. Everything happens on your smartphone.

Speed

Compared to traditional DNA testing, our service delivers results fast. You no longer need to wait hours or days for answers. Our neural networks process and analyze photos in real time, providing results almost instantly.

Innovation

Experience the power and usefulness of new technology. We use advanced machine learning and neural networks to analyze and compare faces in photos. Our system was trained on thousands of images and keeps improving, delivering fairly high accuracy — up to 80%.

Price

Our photo-based kinship services can save you money. Unlike DNA tests, our service offers an effective and affordable way to search for relatives and check paternity, because there’s no need for expensive equipment and related costs. Determine kinship online without leaving home — and save on extra expenses!

FAQ

What does the service offer?This service is designed to help you find relatives, uncover the mystery of your origins, or learn more about your child’s origins. To do this, we created a one-of-a-kind, innovative paternity / close-kinship test, as well as a face-similarity check — fast and affordable, essentially instant.
What is the idea behind this kinship test?The test is based on the premise that close relatives share facial parameters that are more than just a resemblance visible to the naked eye. You could call it a shared “mood” or “vibe” of the face. Your face is an external visual expression of your phenotype (which is known to be shaped by your genotype). Like a mirror, it reflects traits driven by your genes — inherited from your mother and father, or more distant relatives to varying degrees (see www.frontiersin.org/articles/10.3389/fgene.2018.00462/full). That’s why outward similarity often suggests kinship — something people noticed long before DNA testing existed. This natural ability to recognize similarity among close relatives by face developed through evolution. Its existence supports the link between resemblance and kinship. Now, with technology, we can estimate kinship from faces more precisely and impartially — helping you better understand your genetic heritage.
What algorithms does the test use?The test uses machine-learning algorithms (including neural networks) that learn patterns in the facial features of close relatives — such as parents and children, and brothers and sisters.
How accurate is this kind of test?A photo-based test for close kinship or paternity has an average accuracy of about 80% (significantly lower for infants). That’s fairly high — and in some cases it may reduce the need for a DNA test. Keep in mind that even DNA tests are not 100% error-free and can be affected by human factors, since they pass through many hands.
What’s important to know about this method?A key feature of this test is high precision for positive results and lower precision for negative results. For example, if a father has doubts and tests a presumed parent–child pair (not random people), a positive result often indicates a high real-world likelihood of paternity. A negative result, however, does not guarantee there is no kinship — a child may have a phenotype that strongly resembles the mother or even more distant ancestors. So the test can help you save money on DNA testing by addressing initial doubts — but not in every case. In some situations (for example, when only photos remain, or DNA testing is not possible), this test can be invaluable for identifying kinship and searching for relatives.
How do you get the most useful information from the test?Our test is not (yet) a full replacement for DNA testing, but you can approach it strategically to improve reliability and get the most value. For example, if you were adopted and are searching for your mother, you may find several women with the same name on social media. Compare your photo with each of them — the highest kinship probability is likely to point to your biological mother. Narrowing the search like this, combined with our test, delivers the best results.
What about testing infants?Testing children under 3 is our weak spot: infants’ faces are not fully formed, and you can find “similar” traits with almost anyone if you try. So you should treat such results more critically than others. We are working on improving kinship prediction for babies based on facial features.
What are the photo requirements?Rules that increase your chances of a successful and accurate test: one photo — one face; the face should not be covered and should be front-facing; a passport-style photo is the best choice. The face should be as detailed as possible. The upload order doesn’t matter (except for tests where stated otherwise), and people of similar age tend to produce more accurate results. IMPORTANT: remember that front smartphone cameras often mirror selfies (to check whether a photo is mirrored, take a picture against any readable text). Mirroring a face (like any distortion) can cause unreliable results. Also, use each test for its intended purpose to get meaningful information.
How can I improve the result if I’m not satisfied?If you’re not happy with the result, repeat the test using other photos where faces are clearer, with a neutral expression, without obstructions, and strictly front-facing.
A compatibility test by photo — are you serious?Yes. Even though this test is meant as entertainment, it performed exceptionally well in checks. Funny enough, it seems the test really can predict a strong heterosexual marriage.
What does the face similarity test do?This test does exactly what its name says: it compares faces for resemblance. It doesn’t use the full set of technologies found in our other tests — it’s based on a relatively simple algorithm. It’s an entertainment test and does not provide practical, actionable information.
What does the “Who does the child look more like?” test do?This test compares the child’s face to both parents for resemblance — try it as a challenge! It also doesn’t use the full set of technologies found in our other tests — it’s based on a relatively simple algorithm. It’s an entertainment test and does not provide practical, actionable information.
Is a prenatal photo test possible?Technology keeps moving. We are developing a way to run paternity testing for children still in the womb. Unlike DNA testing, such a test would not put either parent in an awkward position and could help avoid relationship conflicts. Once this becomes possible, we will add it to our list of tests.
Can you check paternity without a DNA test?If you’re asking “how to know if the child is mine without a paternity test,” “how to determine paternity without DNA,” or “how to find out who the father is without a DNA test,” our answer is: you can now take an online photo-based test. However, we must emphasize that our algorithm should not be used as the sole basis for life-changing decisions. If establishing true kinship is critically important to you, we strongly recommend using more accurate methods alongside our test — such as DNA testing, which can provide a much higher level of accuracy and reliability.
