Our Analysis
PPT Master does that. Feed it any document and it generates editable PPTX files with actual design, not just text on slides. The output is real PowerPoint files you can open in PowerPoint, Google Slides, or Keynote and edit normally. It's not a screenshot or PDF; every element is editable. The repo includes 15 example presentations spanning 229 pages so you can see the quality before you try it. MIT licensed, Python. The catch: 'beautifully designed' is doing a lot of work. The output is better than what most people make manually, but it's not going to match a professional designer's work. Complex layouts, custom brand guidelines, and precise formatting still need human touch-up. And it's AI-dependent; the quality of the slides tracks the quality of the model you point it at.
Recordly is the open source alternative to Screen Studio for polished screen recordings, tutorials, and bug reports. It records your screen, lets you edit the footage, and produces professional-looking product videos with zoom effects, cursor highlighting, and clean exports. This is specifically for product and developer content. It's not a general video editor. It's optimized for the 'record my screen, make it look polished, export' workflow that Screen Studio popularized. The catch:. The license is listed as 'Other' which means you need to check the repo for exact terms before using it commercially. And it's newer than Screen Studio: fewer export options, less polish on edge cases.
