Nice and possibly useful down the line. If it's of any interest, there was some work done on the problem of "text-to-powerpoint" some years ago (https://arxiv.org/abs/1903.09308, https://github.com/korymath/talk-generator/tree/dev). Being tailored to the "improvised TED talk" format however it wasn't really trying to do a serious job. It's essentially a random content generator doing a random walk on the ConceptNet graph and scraping data related to the input text (topic or title). It relies on templates, so no juicy GPT action. The demo website is still up.
