I wanted a presentation toolkit I could quickly open and use anywhere on my Mac. Something with the tools I need, but also a way to save and reuse what I draw. Most alternatives I found either focused on annotation or required a cloud-based workspace. So I built TeacherPalette. Draw on any screen, guide attention, move to a multi-page whiteboard, bring in PDFs, and save your work for later. No accounts or cloud required. Just open it and start explaining.
