The tool, which was presented at an INFORMS webinar, now includes AI features for generating entire presentations or expanding branches in real-time.", "body_md": "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](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.\n\nComments URL: [https://news.ycombinator.com/item?id=48782206](https://news.ycombinator.com/item?id=48782206)\n\nPoints: 1\n\n# Comments: 0", "url": "https://wpnews.pro/news/show-hn-a-tree-based-replacement-for-powerpoint", "canonical_source": "https://presentation.ironactionai.com/", "published_at": "2026-07-04 02:41:57+00:00", "updated_at": "2026-07-04 02:49:28.536056+00:00", "lang": "en", "topics": ["ai-tools", "generative-ai", "developer-tools"], "entities": ["PowerPoint", "INFORMS"], "alternates": {"html": "https://wpnews.pro/news/show-hn-a-tree-based-replacement-for-powerpoint", "markdown": "https://wpnews.pro/news/show-hn-a-tree-based-replacement-for-powerpoint.md", "text": "https://wpnews.pro/news/show-hn-a-tree-based-replacement-for-powerpoint.txt", "jsonld": "https://wpnews.pro/news/show-hn-a-tree-based-replacement-for-powerpoint.jsonld"}}
