Most people guess their face shape from a mirror or a random online quiz, but StarDoppel's Face Shape Detector replaces guesswork with actual measurement. The AI maps dozens of facial landmarks — forehead width, cheekbone position, jaw angle, and total face length — and classifies your face into one of six categories: oval, round, square, heart, diamond, or oblong. Live since September 2025, the tool has already processed over 100,000 photos. Along with your shape, you get personalized hairstyle, makeup, and eyewear recommendations tailored to your specific structure. Completely free, no account needed, and results appear in about 10 seconds.
