When you need help — an solution, a figure, a computation, or a hint — tap once and watch it appear line by line, handwritten below your own!  This is Note Completions -- A new interaction paradigm build for the handwriting canvas. ColloidNote can run Python for scientific computing, generate flowcharts, plots and figures, and collaborate on your uploaded PDFs — all without you ever leaving your canvas. ColloidNote is also a complete handwriting application — everything you need to take notes, sketch, and think on paper is available for free!
