What is Magic Sketchpad?

Magic Sketchpad is a free online drawing tool that uses machine learning to assist with sketch creation. Built on the Magenta.js library within TensorFlow, it works by predicting and completing drawing strokes in real time based on categories you select. As you draw, the AI offers suggestions for how to finish or refine your lines, creating a collaborative experience between you and the algorithm. The tool is designed for artists of all skill levels, from complete beginners to experienced practitioners. It works particularly well for quick concept sketching, character design, and shape exploration. Because it's open source, the community can contribute improvements and modifications. It's also useful in educational settings where students want to understand how machine learning can assist creative work.
