We tested MS CoPilot at work and by far the most disappointing application was PowerPoint. Despite repeated attempts, no one could get it to make a decent deck, or even a good starting point.

By far the best AI-built presentations I’ve seen recently were actually HTML, not PowerPoint. Built with Claude Code and hosted on GitHub pages. The LLM easily handled external assets like text, images, and videos, and produced a series of elegant transitions from element to element, and screen to screen.
