Draw Coach

A drawing coach that checks every line.

Draw the missing lines of a picture. Each one is scored the moment you lift the pen, with a colour that shows which way to correct it. Guide lines fade level by level until you can draw the whole picture without them.

Lessons

Your drawings

Trace each line in one go, the way you'd draw it. The longest line, shown in violet, stays visible on the final level.

Choose an image to trace, or drop or paste one here. You can also trace on blank grid paper.

Settings

Closeness neededLines scoring at least this stay on the paper and count. Each line is scored from 0 to 100 on how close it runs to the right line, where it starts and ends, and how smooth it is. Its worst part counts extra.
ToleranceHow far off a line can be, as a share of the drawing's size. A line drawn half this far off scores about 75. Short lines are judged more tightly. Lower is stricter.
