What is it?

PPT Master is a workflow, packaged as a skill, that runs inside an agent-capable AI tool such as Claude Code, Cursor or Codex CLI. You give it source material like a PDF, DOCX or web page, or just a topic, and it analyzes the content, designs the slides as SVG, and exports a .pptx file with native PowerPoint shapes, text, pictures and fills that stay editable in PowerPoint.

It can also produce data-backed charts and tables as native PowerPoint objects, add transitions, animations and audio narration generated from speaker notes, and build decks from your own .pptx templates. For existing decks, it can fill new content into a file while keeping the original design and unchanged pages. The pipeline runs on your machine, and only AI model calls leave it. Python 3.10+ is required.

  3. 3

    Drop in your source material and ask the AI in chat to make a deck from it

Things to know

  • Output quality depends heavily on the AI model; the README recommends large-context models and says others show a quality gap.
  • The only cost is your AI model usage, so you need access to a paid or self-funded model.
  • Expect to polish the generated deck yourself; it is not a finished deck in one pass.
  • Beginners without Python or AI agent experience face a learning curve.
