MAC SlideGenerator is a desktop application for Mac that leverages large language models to produce polished Keynote presentations from user-provided text or bullet outlines. It generates slide titles, bullet points, speaker notes, and visuals, then compiles them into a .key file. Users can choose from predefined themes or customize colors and fonts. The tool streamlines slide creation, reducing hours of manual formatting into seconds by automating layout decisions, graphic insertion, and inline content editing.
