Nanorater is a free AI face rating and attractiveness test website. Users upload a clear face photo and receive a 0–100 score, visible reasons behind the score, and one improvement suggestion to try. No registration is required for the first AI result.
[Main capabilities] The tool has two layers. The first layer is the instant face map: completed in the browser in about one second, with no photo upload, no account required, and no limit on the number of photos. It uses Google's MediaPipe Face Landmarker to find 478 points on the face and measures four things—mirror balance of the left and right sides around the midline (after correcting for head tilt), thirds of the visible face, fifths of the width, and facial aspect ratio—and compares them with typical values from a reference set of 1,088 horizontal front-facing face photos from a public face dataset. The comparison formula is shown in the results. The second layer is AI photo scoring: a vision AI model views the photo, scores the visible content from 0–100 against six criteria, and explains the evidence. Before scoring, a separate step reads the photo conditions (camera angle, eye level, light direction, background, and cropping), so a selfie with harsh shadows is judged as a lighting issue rather than a problem with the person. The six criteria include: facial harmony (proportions, symmetry, thirds), symmetry and balance (left-right balance and feature alignment), skin quality (tone, evenness, texture, and healthiness), eyes and expression (gaze, brows, and confidence and approachability in the eyes), lighting and color (whether the light flatters the face and whether skin tone is natural and true), and styling and grooming (hair, grooming, and finishing details). The role or tone chosen by the user only changes the wording of the feedback, not the score.
[How to use]
- Upload a photo: choose a recent, unfiltered photo where the face is clearly visible; front-facing, eye-level, soft lighting gives the fairest result.
- View the instant face map: in about one second, the browser draws mirror balance, thirds, fifths, and aspect ratio on the photo and shows where each item stands compared with the reference set.
- Get the AI photo score: the AI gives a 0–100 score based on six criteria and explains what it sees in plain language.
- Change one thing and rate again: face a window, raise the camera to eye level, or relax your expression, then rate again to see the change. No registration is required for the first result, and visitors receive the score and a short summary; a free account can unlock the full single-photo report, including evidence for each dimension and a retake plan. Free accounts have a rating limit, as shown in the account. There is also an optional one-time payment of $17.49 for the Glow-Up report, which includes an expectedUse the improved AI preview image. The privacy policy explains photo storage and AI processing.
[Use cases] This tool is suitable for users who want to understand how a photo comes across, choose a better photo, or improve their next shot. A high score does not mean a person has high personal worth; it is feedback on a single photo. The score bands have meaning: 90–100 excellent, the photo presents very well with only negligible limitations; 80–89 strong, effective and directly usable; 70–79 good, mostly effective but with one obvious limitation or a few minor limitations; 60–69 mixed, with some merits but one substantial limitation (often lighting or angle) weakens the photo; 40–59 weak, with multiple substantial limitations such as heavy shadows, blur, or extreme angles, and retaking may help the most; 0–39 unreadable, the face is missing, obscured, or unrecognizable in the photo.
[Limitations and notes] The same face scores differently in different photos because camera distance, light direction, expression, and cropping all change what is visible. The same photo may also differ by a few points between runs, and small differences should be treated as noise. The tool clearly states: it scores photos, not a person's worth; it is not medical or psychological advice, does not diagnose conditions, and does not recommend procedures; vision models may carry biases, and some skin tones, face shapes, and features may be overrepresented or misread in the training data. Research shows that symmetry, averaged proportions, skin health cues, and warmth of expression can affect attractiveness ratings, but a photo test cannot see who the viewer is, what they value, or show real-world attractiveness factors such as voice, movement, and warmth. If a low score causes psychological strain, it is suggested to leave the page, retake the photo another day in better lighting, or ignore the score.
