FaceTwin turns one selfie into three answers: who you resemble, how your features measure up, and what you would look like as a drawing. Upload a photo and a compact face model runs entirely in your browser, placing 68 landmarks on your brows, eyes, nose, lips and jaw. From those points it finds your top five celebrity lookalikes from an index of more than 2,300 public figures, with similarity percentages and the features you share, plus a 1-10 face geometry score, your face shape, symmetry by region with a heat map, golden-ratio proportions, facial thirds, eye tilt and a percentile against 1,196 public figures. Every measurement is explained on the photo itself, and nothing is uploaded: the free analysis works even with Wi-Fi switched off. A first AI caricature in one of six styles is free, with further portraits at 10 credits and a full styling report with PDF at 30 credits; credit packs start at $4.99 and there is no subscription. The site is adults only and for your own photo, never generates images of celebrities, and deletes uploaded photos automatically. FaceTwin suits anyone curious about their celebrity matches or facial proportions who wants the analysis done privately on their own device.
