Magic Sketchpad is an AI tool crafted for creative design that harnesses machine learning to complete user sketches.

The process begins when the user starts to draw and each time the pen lifts from their canvas, a machine learning algorithm springs into action.

This algorithms aim is to finish the user's stroke in a manner that fits their chosen category.

The tool adds an element of exploration as it allows drawing of multiple categories in one setting.

Its core strength lies in the interaction between user input and machine intelligence to create unique outcomes.

The tool was developed by an individual using the online handle '@notwaldorf' and it uses magenta.js, a software library focused towards art and music and built by TensorFlow.

A further feature is Sketch RNN, which is likely a recurrent neural network trained to predict underspecified sketches based on the user's pen strokes.

The code base for the Magic Sketchpad tool is available for public view and modification on Glitch, an online community for developers.
