PPT Master

PPT Master is an open-source tool that converts source documents into PowerPoint presentations where every element is a native, editable PPTX shape rather than a rasterized image. That distinction matters: most AI deck generators produce slides you can barely tweak afterwards, whereas PPT Master's output drops into PowerPoint or Keynote and behaves like a deck a human built. It ships with template families covering Consulting, General, Creative, and Editorial styles.

The project is MIT-licensed and lives on GitHub under Hugo He, with a marketing landing page on GitHub Pages and a quick-start guide for self-hosting. There's no obvious managed SaaS or pricing page, so practical use means cloning the repo, wiring in your own LLM key, and running it locally or on your own infra. That makes it best suited for developers and power users who want full control over prompts, templates, and model choice rather than a polished web app for non-technical staff.

Because the underlying model isn't fixed by the project itself, you can point it at whichever provider you prefer, and the output is friendly to existing brand-template workflows. The trade-off is the usual open-source one: documentation is light, there's no support contract, and the burden of running it (and paying for the model calls) falls entirely on you.
