Curious about your face shape? Want to know your exact eye color classification? Wondering how symmetrical your facial features are? AI face analysis tools can answer all of these questions instantly — and for free. Upload a selfie and get detailed analysis of your facial features, proportions, skin health, and more.
In this guide, we cover every AI face analysis tool available on just build things, explain what each one does, and show you how to get the most accurate results.
Modern AI models can detect and analyze facial features with remarkable precision. Powered by deep learning face analysis techniques, when you upload a photo, the AI identifies facial landmarks — eyes, nose, mouth, jawline, forehead, and cheekbones — then measures proportions, symmetry, and characteristics to deliver detailed analysis.
The results are educational and informative. Royal Society research shows that facial symmetry and proportions influence how others perceive us, making these insights practically useful for decisions about hairstyles, glasses, makeup, and personal style.
Understanding your face shape is the foundation for making better style decisions — from choosing the right hairstyle to picking flattering glasses and necklines.
The Face Shape Analyzer identifies whether your face is oval, round, square, heart, oblong, diamond, or triangle-shaped. It explains the characteristics that define your shape and provides style recommendations specific to your face type.
This is one of the most practical tools — once you know your face shape, you can look up hairstyles, glasses frames, and makeup techniques that are specifically recommended for your shape.
The Jawline Analyzer evaluates your jawline structure, definition, angle, and symmetry. It assesses jawline prominence and provides detailed observations about this key facial feature.
The Nose Shape Analyzer categorizes your nose type and analyzes its proportions relative to other facial features. It identifies characteristics like bridge width, tip shape, and nostril size.
The Hairline Analyzer examines your hairline shape, position, and symmetry. It identifies your hairline type (straight, widow's peak, rounded, M-shaped, etc.) and suggests hairstyles that work well with your specific pattern.
The Eyebrow Shape Analyzer classifies your eyebrow shape, thickness, arch, and symmetry. It provides grooming tips and identifies which eyebrow shapes complement your face.
The Eye Color Analyzer is our most popular tool. It goes far beyond simply saying "brown" or "blue" — it identifies specific color variations, patterns, and unique characteristics in your iris. You might discover you have central heterochromia, amber flecks, or a rare limbal ring pattern.
The Eye Shape Analyzer classifies your eye shape (almond, round, hooded, monolid, downturned, upturned, etc.) and provides makeup and styling tips tailored to your specific shape.
The Skin Health Analyzer evaluates visible skin condition including texture, tone evenness, hydration appearance, and common concerns. It provides observations and general skincare suggestions based on what it detects.
The Skincare Analysis focuses specifically on your skincare needs. Upload a clear face photo and get analysis of skin type indicators, visible concerns, and routine suggestions tailored to what the AI observes.
The Skin Type Identifier helps determine whether your skin appears dry, oily, combination, normal, or sensitive based on visual indicators. Knowing your skin type is the first step to building an effective skincare routine.
The Lip Shape Guide analyzes your lip shape and proportions, identifying your lip type and suggesting flattering lip colors and techniques.
The Makeup Style Finder recommends makeup styles, colors, and techniques that complement your specific facial features, skin tone, and face shape.
The Facial Harmony tool analyzes the proportional relationships between your facial features. It evaluates symmetry, the golden ratio, and how features relate to each other, providing an educational breakdown of facial proportions.
The Age Estimation tool estimates your perceived age based on facial features, skin condition, and other visual indicators. It is a fun way to see how old (or young) the AI thinks you look.
These tools analyze how your photos might be perceived by others:
These are designed for self-awareness and improvement, helping you understand the impressions your photos create.
Beyond the face, related tools analyze your full appearance:
Once you know your face shape, coloring, and body type, these tools help with style decisions:
Use a clear, well-lit front-facing photo. Natural daylight works best. Avoid harsh shadows, filters, and heavy makeup for the most accurate analysis.
Keep a neutral expression. For shape and structure analysis, a relaxed, neutral face gives the most accurate measurements. Smiling changes jaw and cheek appearance.
Remove glasses and pull hair back. For face shape and jawline analysis, the AI needs to see your full face outline. Glasses can interfere with eye analysis too.
Try multiple photos. Different angles and lighting can produce slightly different results. Analyze 2-3 photos for a more complete picture.
Use the results for style decisions. The real value of face analysis is applying the insights — once you know your face shape, look up hairstyles and glasses specifically recommended for that shape.
Yes. All face analysis tools are available for free on just build things. Some features may require a free account.
Photos are processed by the AI for analysis and are not permanently stored or shared. They are used only for the duration of your analysis session.
AI face analysis provides well-informed assessments based on advanced computer vision. Results are consistent and educational, though they should be taken as informative guidance rather than medical or definitive assessments.
Start with the Face Shape Analyzer — knowing your face shape is useful for virtually every other style decision. Then try the Eye Color Analyzer for a fun deep dive into your eye color.
Upload a selfie and discover what AI sees in your features. From face shape and eye color to skin health and style recommendations, these tools give you detailed, personalized insights in seconds.
