Take Handwritten Notes
In addition to drawing diagrams and sketches, you can of course use the Apple Pencil to take handwritten notes as well. Although it’s not quite yet sophisticated enough to turn this into typed text, Apple’s Notes app and built-in iOS spotlight search does have the ability to search for notes based on your handwriting, so as long as it doesn’t look like complete chicken-scratch, there’s a good chance you’ll be able to easily find your handwritten notes again in the future. It’s a very handy feature if you prefer freeform script versus pecking things out on your iPad keyboard.
