Training tools
Interactive tools to practice, study references and understand theory. Everything runs in your browser: nothing is uploaded.
Sketchpad
A simple drawing canvas with pressure-friendly brushes, guides and undo. Works with mouse, touch and pen.
Line Trainer
Connect the dots with one confident stroke and get a score for straightness and accuracy.
Ellipse Trainer
Draw ellipses inside a guide and get feedback on smoothness, symmetry and closure.
Gesture Timer
Timed figure-drawing sessions with randomly posed mannequins, from 30-second gestures to 5-minute studies.
Perspective Grid
Drag the horizon and vanishing points to see one-, two- and three-point perspective build a box in real time.
Value Scale Trainer
Train your eye to judge values: match grays, sort a value scale and check the value of any color.
Color Wheel & Harmonies
Pick a base hue and explore complementary, analogous, triadic, split-complementary and tetradic palettes.
Reference Studio
Open a photo to study it: grayscale, simplify into 2–5 values, blur (squint), mirror and add a drawing grid.
Figure Proportions
Compare the human figure in head units: realistic, idealized, heroic, child and stylized proportions.
Light Lab
Move a light around a sphere, cube or cylinder and see the highlight, core shadow, reflected light and cast shadow change.
Drawing Prompts
Stuck on what to draw? Generate a random subject, a twist and a time limit for your next sketch.
