About FaceSymAI
What Is FaceSymAI
FaceSymAI is a browser tool that measures how symmetrical a face looks in a single photo. It is built by the team behind howolddoilook.io and runs at the face-symmetry-test.com site. The idea is narrow on purpose. Instead of guessing at an overall impression, it finds your face, places 68 landmark points, and compares the left and right sides of seven features against a vertical line down the middle. The result is a number you can read feature by feature.
As a facial symmetry checker, its appeal is that it shows you where the difference sits. A single verdict like "asymmetrical" tells you nothing useful. FaceSymAI scores the eyes, eyebrows, ears, nose, mouth, and upper and lower cheeks separately, so you can see which pair carries the gap and how large it is. That turns a vague question into something closer to a measurement.
Two limits shape its use. It reads one photograph, not your face in general, so lighting and head angle move the score as much as your features do. And it measures geometry only. It does not judge skin, age, hair, or identity, and it does not perform face recognition. Treat the number as a reading of that shot, not a fixed property of you.
Getting Started
- Open face-symmetry-test.com in any modern browser. There is no sign-up, no account, and no app to install.
- Drop in a photo or choose one. JPG and PNG both work, and you need a single face looking roughly straight at the camera.
- Wait for the analysis. A detector locates the face, a landmark model places 68 points, a midline is drawn, and each of the seven pairs is compared.
- Read the result. You get an overall score plus a per-pair breakdown, and the cropped face is shown back to you.
- Run a second or third photo of the same face to see how much of the number comes from your features and how much from the shot.

Key features
The 68 Landmark and Midline Method
The core of FaceSymAI is landmark detection followed by arithmetic. A detector finds the face and crops around it, then a landmark model marks the jaw line, both eyebrows, both eyes, the nose, and the mouth with 68 points. A vertical midline is fitted through the centre, and every measurement is a distance from that line. There is no black box, and the site spells the four steps out.
Seven Feature Pairs Scored Separately
Each of seven pairs is scored on its own, so you see which part of the face carries the difference instead of a single verdict. Eyes, eyebrows, ears, nose, mouth, and upper and lower cheeks each get their own comparison of left point distance against right point distance. The average of the seven is your overall number.
A Number You Can Read as a Range
The score runs on a scale the site explains in bands. From 95 to 100 the differences are smaller than the noise in an ordinary photo. From 88 to 95 the gaps are small and evenly spread. From 80 to 88 one or two pairs sit clearly off the midline. Below 80 the tool suggests a better photo before you read anything into it.
Privacy by Design
Only geometry is extracted. The tool reads the positions of the 68 points and the distances between them, and it does not measure skin, hair, age, or identity. No face recognition runs. The photo is processed in memory, handed to the results page, and then discarded, with nothing written to a database or used for training.
Photo Quality Guidance
The measurement is only as good as the photo, and the tool says so. It lists the four things that move the score most: flat even light, a head square to the camera, a plain background, and a clear face with hair, glasses, and hats out of the way. That guidance is what makes repeat readings comparable.
Free With No Account or Limit
The facial symmetry analysis is completely free, needs no account, and puts no cap on how many photos you run. Advertising on the site covers the running cost. You can try several photos in one sitting without signing up for anything.
Pros and cons
Pros
- Completely free with no account and no limit on how many photos you analyse.
- The per-pair breakdown shows which features carry the difference, not just a single overall verdict.
- The method is explained step by step, so you can see how the number is produced rather than trusting a black box.
- The photo is processed in memory and never stored, which suits a private one-off check.
- The shooting guidance makes repeat readings comparable when you keep light and pose consistent.
Cons
- It reads a single photo, not your face in general, so lighting and head angle can move the score by a few points.
- Faces covered by hair, glasses, or hats, or turned away from the camera, measure less reliably and can skew the result.
- Group photos only measure the largest face in the frame, so anyone further back is ignored.
- There is no API and no way to plug the measurement into another app or workflow.
- The number is not a medical or aesthetic assessment, so it should not be read as a verdict about your appearance.
