FAQ

What is Relatives.photos and how do I use it?Relatives.photos is an online service for analyzing faces in photos. It helps estimate the probability of close kinship, check the visual similarity between two faces, and determine whether the same person may appear in different photos. Simply choose the type of check you need and upload the photos.
Can kinship be determined from a photo?Yes, our AI system can estimate the probability of close kinship based on facial features in a photo. This is not an entertainment-style “looks alike / doesn’t look alike” comparison, but a deeper analysis of facial traits. The result should be treated as a preliminary assessment, not as legal proof.
How does kinship and similarity analysis from photos work?The service analyzes key facial features using computer vision and machine-learning algorithms. In kinship mode, it estimates the probability of a close biological relationship from photos; in similarity mode, it evaluates only the visual resemblance between faces. Similarity and kinship are different tasks and different types of analysis, so they should not be confused.
How accurate is kinship detection from photos?On an independent face-based kinship benchmark, our model scored above 83% on a key quality metric. For such a difficult task, this is a high level. In real-world checks, accuracy depends on photo quality, the people’s age, angle, facial expression, and other factors.
Can I check paternity online from photos?Yes, the service can provide an AI-powered estimate of paternity probability from photos online. It is a fast and confidential way to get a preliminary reference point when you need an initial answer without complicated procedures. This test does not replace DNA analysis and should not be the sole basis for life-changing decisions.
Is there such a thing as a DNA test from a photo?A full DNA test from a photo does not exist. However, our AI system can deeply analyze faces and estimate the probability of kinship from photos. This is not a laboratory genetic analysis, but a convenient online way to get a preliminary reference point.
How can I get a more accurate result when checking kinship from photos?It is better to use several high-quality photos of each person (photo batches), rather than one random shot. The most useful photos are front-facing, without filters, strong facial expressions, glasses, hats, or other distortions. If there are several presumed relatives, it makes sense to check all possible options: this usually makes the result more stable and informative.
What photos are suitable for checking kinship and similarity?Clear photos work best, where the face is clearly visible, unobstructed, and front-facing. Good lighting, a neutral facial expression, and no harsh shadows or digital filters are recommended. If you are taking a selfie, check whether the photo has been mirrored: this can make the result less accurate.
Can infants and young children be checked for kinship from photos?Yes, but such results should be interpreted especially carefully. In children under 3, facial features are still changing rapidly, so the reliability of the assessment is noticeably lower than for adults. In these cases, it is especially important to use several high-quality photos and not draw conclusions from a single test.
How can I compare two faces in photos and find out how similar they are?Simply upload two photos, and the service will calculate the degree of visual similarity between the faces. This test shows visual resemblance only and does not determine kinship. It is suitable for quickly comparing faces online, but not for drawing conclusions about paternity or a person’s origins.
Who does the child look more like based on the parents’ photos?This mode compares the child’s face with the parents’ faces and shows which parent the child visually resembles more. The result refers only to visual similarity and is for entertainment and informational purposes. It should not be treated as proof of kinship or as a replacement for a paternity test.
Can you tell from photos whether it is the same person?Yes, the service can estimate the probability that different photos show the same person. It analyzes stable facial features, not just the overall visual impression.
Is there a free online photo check?Some service features may be available in a trial format, but the photo-based paternity test will not be free. A sensitive and serious type of analysis should not look like a casual free “toy”; otherwise, trust in its results will be lower. That is why serious kinship and paternity checks are available only in the full format.
Can paternity be checked without taking a DNA test?If you are asking “how can I know if the child is mine without a paternity test,” “how can I determine paternity without DNA,” or “how can I find out who the child’s father is without a DNA test,” our answer is: you can now take an online test. However, we must emphasize that this test does not replace DNA analysis and should not be the sole basis for life-changing decisions. But it can be useful as a first reference point when you need a quick answer or when a DNA test is unavailable.
