What it does PPT Master is a Python-based workflow you run inside an AI IDE (Claude Code, Cursor, VS Code Copilot). Feed it a document, chat with the AI, and it generates a genuine .pptx — native DrawingML shapes, editable text boxes, slide transitions, entrance animations, and speaker notes that can be voiced as audio narration. You can also point it at your own template instead of starting from scratch.

The interesting bit The author, a finance professional who regularly edits decks, built this specifically because most “AI presentation” tools export flat images stuffed into a PPTX wrapper — useless for actual editing. The README is unusually honest: it calls the project a “harness, not a complete agent” and admits cheaper models mean more cleanup work for you. The real pitch is almost meta: learning to wield Python plus AI agents matters more than the slides themselves.

Key highlights

• Outputs real editable PowerPoint elements, not rasterized slide images
• Supports custom .pptx templates, native animations, and audio narration from speaker notes
• Runs locally; only AI model API calls leave your machine
• Works across Claude, GPT, Gemini, Kimi, etc. — though the README stresses Claude with ~1M context window plus gpt-image-2 hits the quality ceiling
• Free and MIT-licensed; you pay only for model usage, no SaaS markup

Caveats

• Requires comfort with Python, pip installs, and an AI IDE — not a one-click web app
• The author explicitly warns: “Don’t expect it to hand you a finished, perfect deck in one shot”
• Best results are tied to premium models; cheaper alternatives “can run the pipeline but cannot reach the same quality ceiling”

Verdict Worth a look if you regularly build presentations and already live in AI IDEs or want an excuse to learn them. Skip it if you need a polished deck in five minutes with zero setup — this is a power tool, not a wishing well.
