How Does Our Facial Recognition AI Work?
In just a few seconds, Look Like Me tells you which parent you resemble most. But what's really happening under the hood? Here's how our artificial intelligence analyses your faces.
Azure Face API: the technology behind the score
Look Like Me relies on Azure Face API, developed by Microsoft and trained on billions of images. It's one of the most accurate facial recognition technologies available today, used by thousands of companies worldwide.
As soon as you submit your three photos, the API automatically detects faces and extracts what are called embedding vectors — a unique mathematical representation of each face, composed of hundreds of numerical values.
- Real-time face detection
- Extraction of 27 key facial landmarks (eyes, nose, mouth, jaw, cheekbones…)
- Calculation of a high-dimensional vector for each face
Cosine distance: measuring similarity
Once the vectors are extracted, the algorithm calculates the cosine distance between your face and each of your parents'. The smaller the distance, the closer the vectors — and the more the faces resemble each other.
This calculation considers the overall geometry of the face rather than raw pixels. This means that two photos taken under different lighting conditions or at different ages still yield a reliable result.
The final score you see is a normalisation of this distance: 0% means no detectable resemblance, 100% means nearly identical faces (what you'd see comparing a photo of yourself to itself).

It's important to understand the technology's limitations. The AI analyses only facial geometry, not genes or DNA. It cannot predict who you'll look like in 10 years, nor identify potential genetic conditions.
It can also be influenced by external factors: heavy make-up, a thick beard, wide glasses, or poor image quality. For best results, we recommend recent, well-lit, front-facing photos.
Privacy and data deletion
Your photos are never shared with third parties. The facial vectors computed by the API are not stored on our servers — only the final score is kept to display your result. Original photos are automatically deleted after 12 months of inactivity, in line with our GDPR policy.
You can request immediate deletion of your account and all your data from your profile at any time.
A constantly improving technology
Facial recognition AI is constantly improving. Microsoft regularly updates its models to enhance accuracy, reduce bias, and better handle photos taken under difficult conditions (low light, profile angle, etc.).
At Look Like Me, we closely follow these updates to always deliver the most accurate results. Our goal is simple: give you a reliable answer to a question everyone asks themselves at some point.
