Gamma

Gamma generates presentations from a prompt, an outline or a pasted document, then lets you edit the result as structured cards rather than fixed slides. Content reflows automatically when you change it, which removes most of the manual box-dragging that makes conventional slide editing slow. Decks can be presented in the browser, published as a web page, or exported to PowerPoint and PDF. It is the strongest general-purpose option for people who want a finished deck quickly and do not need to stay inside PowerPoint the whole time.
