PPT Master: open-source AI workflow builds natively editable PowerPoint decks
PPT Master is an open-source Python workflow by developer Hugo He that runs inside any agent-capable AI tool (such as Claude Code or Codex CLI) and turns PDFs, DOCX files, web pages or a bare topic into a natively editable PowerPoint deck — including slide masters and layouts, native shapes and connectors, data-backed charts and tables, transitions, animations and narration from speaker notes, plus support for a user's own .pptx templates. The project bills itself as free and open source with no PPT subscription, with everything except model communication running on the user's machine to avoid platform lock-in. The author recommends a large-context model (Kimi K3 or Claude) paired with an AI image generator such as gpt-image-2 or gemini-nano-banana-2.1, and warns that a single pass will not produce a flawless deck; the page also carries sponsor promotions for Kimi, PackyCode, APIKEY.FAN, RunAPI and APIMart.
A frequent complaint about AI slide tools is that they output flat images or filled-in templates rather than editable objects, and this project offers a locally runnable route to native PowerPoint output.
