Show HN: A tree-based replacement for PowerPoint

As a former professor turned industry consultant / frequent presenter in industry, I got sick of Powerpoint: the linear sequence of slides was hard to navigate in live QA sessions, show the whole picture to the audience at once, and divide up for collaboration ... I realized this could all be solved by moving to a tree-based 2D-3D format, based on a source JSON file which holds all the node structure, text and multimedia links, which is what I developed a few months ago and actually presented at a live webinar for INFORMS (https://www.youtube.com/watch?v=vXN2xu4z5qA). Now I have enhanced it with AI (you can generate whole presentations or expand from a given branch in real-time) and would love to have the community try it out.
