AI Body Analysis Tools
Our AI body analysis tools give you a fast, photo-based estimate of body composition and physique metrics popular in the fitness community — from body fat percentage to genetic muscle potential. These tools are for general interest and entertainment purposes only and are not a substitute for professional medical, health, or fitness advice. Curious where you stand? Pick a tool below and get your estimate in seconds.
Body Fat Percentage Calculator
Skip the calipers and skip the guesswork. Upload a clear, full-body photo and our AI visually estimates your body fat percentage based on muscle definition, fat distribution, and body shape — the same kind of visual estimation trainers use, powered by AI. Curious where you actually stand? Upload a photo below and get your estimate in seconds.
See your result — freeWhat's My Body Type?
Ectomorph, mesomorph, or endomorph? Upload a full-body photo and our AI analyzes your bone structure, muscle distribution, and overall build to estimate your body type (somatotype) — a classic fitness framework used to guide training and nutrition approaches. Upload your photo below to find out which type fits you best.
See your result — freeHow Good Is My Physique?
Popular in bodybuilding and fitness circles, the "golden ratio" physique standard compares shoulder, waist, and chest proportions to classical ideals of aesthetic symmetry. Upload a full-body photo and our AI scores your proportions against this standard and gives you a physique rating. See how you measure up — upload your photo below.
See your result — freeGenetic Muscle Potential Calculator
How much natural muscle could you realistically build? Upload a photo along with your height, weight, and wrist/ankle size if known, and our AI estimates your natural genetic muscle-building potential using frame-size and bone-structure indicators — the same general logic behind popular fitness calculators like Casey Butt's formula. Wondering how much more you can realistically build? Upload your photo below and find out.
See your result — freeFFMI Calculator
FFMI (Fat-Free Mass Index) is a well-known fitness metric — similar to BMI but accounting for muscle mass — used to gauge how muscular someone is relative to their height, and often referenced as a natural-bodybuilding benchmark. Upload a photo along with your height and weight, and our AI estimates your body fat percentage to calculate your FFMI. Enter your stats and upload a photo below to see your score.
See your result — freeHow's My Posture?
Desk jobs and phone scrolling take a toll on posture. Upload a side-profile, full-body photo and our AI analyzes visual alignment markers — like head, shoulder, and spine position — to flag common posture patterns such as forward head posture or rounded shoulders. Upload a side-profile photo below to see what your posture is really doing.
See your result — freeRate My Body
"Rate my body" searches usually lead to the same place: a Reddit thread of strangers being blunt, or worse. This tool is built differently on purpose — instead of a cold number out of 10, our AI looks at your overall presentation (style, grooming, posture, general vibe) and gives you specific, kind feedback you can actually use. Curious what a first impression of your photo really looks like? Upload it below.
See your result — freeRate My Abs
Most "rate my abs" content online is either a flattering gym-mirror photo with perfect lighting or a harsh stranger's one-line judgment. This tool aims for something more useful: a specific, honest read on your visible ab definition — accounting for lighting and pose rather than taking the photo at face value — plus one practical observation, never a numeric score. Curious where your definition actually stands? Upload a clear midsection photo below.
See your result — freeHow Attractive Am I?
"How attractive am I" is one of the most-searched appearance questions online, and most answers you'll find are either a Reddit stranger's blunt one-liner or an app that locks the actual result behind a paywall. This tool takes a different approach: no score, no ranking against other people — just a specific, honest first impression of what stands out in your photo. Curious what a genuine first impression of your photo looks like? Upload it below.
