Free AI face analysis tools.

Every tool on RealSmile uses the same underlying technology: a TensorFlow.js face landmark model that detects 68 key points on your face directly inside your browser. These landmarks map the precise positions of your jawline, cheekbones, eyes, nose, mouth, and brow ridge. From those coordinates, each tool calculates different metrics — symmetry ratios, the golden ratio, canthal tilt angles, face width-to-height ratio, and overall harmony scores.

Because the model runs client-side with WebGL acceleration, analysis takes roughly two to three seconds on most phones and under one second on a laptop. There is no server round-trip. Your photo never leaves your device — the pixel data is processed in a canvas element, measurements are extracted, and then the image data is discarded from memory. This architecture lets us offer every tool completely free with no rate limits.

For the Photo Ranker and LinkedIn Headshot Ranker, we go a step further. The AI evaluates multiple photos against each other, comparing expression quality, lighting, background composition, and face positioning to rank them from best to worst. This is especially useful when you cannot decide which selfie to use for a dating app or which headshot looks most professional.

Choosing dating app photos? Start with the Photo Ranker. Upload your top candidates and let the AI sort them objectively. Most users find that the photo they thought was their best is actually their second or third best — subtle differences in lighting and expression matter more than you think.

Self-improvement and looksmaxxing? The Looksmaxxing Test gives you 17 individual facial metrics plus a personalized glow-up plan. It identifies your strongest features and the areas with the most room for improvement, covering everything from jawline definition to skin clarity.

Just curious about your face? The Face Score and Attractiveness Test give you a quick overall rating. These are the fastest way to get an honest, AI-powered assessment without diving into individual metrics.

Researching a specific metric? Use the individual calculators — Golden Ratio, Canthal Tilt, FWHR, Facial Symmetry, or Face Shape. Each one provides a deep dive into that single measurement with explanations of what the numbers mean and where you fall on the distribution.

We built RealSmile with a strict privacy-first architecture. Every face analysis tool on this page processes your photos entirely inside your web browser using TensorFlow.js. Your images are never uploaded to a server, never stored in a database, and never seen by another person. The AI model weights are downloaded once and cached locally — after that, analysis works even with a slow connection.

There are no accounts required, no cookies tracking your face data, and no analytics on the images you test. When you close the tab or navigate away, your photo data is garbage-collected by the browser. We cannot recover it even if we wanted to. This is the same privacy model used by password managers and end-to-end encrypted messaging apps — the sensitive data never touches our infrastructure.
