Turn your phone into a drawing guide for real paper. AR Sketch places a sketch over your live camera view, helping you follow the lines directly on the page. Pick a drawing, position your phone above the paper, and start tracing — even if you are completely new to drawing. DRAW ON REAL PAPER See the guide through your camera while your pencil stays on the page. Adjust the sketch until it fits your paper, lock it in place, and follow the lines at your own pace. HOW IT WORKS Choose a sketch from the library or import your own photo. Position your phone above the paper using a stand or stable support. Move, resize, rotate, and lock the guide. Follow the lines and create the drawing on real paper. 2100+ SKETCHES TO EXPLORE Discover more than 2100 sketches across 26+ categories, including anime, animals, chibi, flowers, people, cars, architecture, and more. LEARN STEP BY STEP Follow 20+ guided AR lessons designed to make complex drawings easier to understand. Build the drawing stage by stage and see how each part comes together.
