PPT Master — AI-Powered Native PPTX Generator

Introduction

PPT Master uses AI to generate natively editable PPTX files from any document. Unlike screenshot-based tools, it produces real PowerPoint shapes with native animations, making the output fully editable in Microsoft PowerPoint, Google Slides, or LibreOffice Impress.

What PPT Master Does

• Converts documents, markdown, and text into native PPTX presentations
• Generates real PowerPoint shapes, charts, and diagrams instead of images
• Applies native slide transitions and element animations
• Supports multiple layout templates and design themes
• Provides both CLI and web-based interfaces for generation

Architecture Overview

PPT Master is a Python application that parses input documents, uses LLM APIs to structure content into slide layouts, and then renders each slide using the python-pptx library. The rendering pipeline handles shape placement, text formatting, chart generation, and animation sequencing to produce standards-compliant OOXML output.

• Configure your LLM API key (supports OpenAI, Anthropic, and others)
• Customize templates by editing the built-in theme files
• Run the web UI with a single command for interactive use
• Deploy via Docker for team access
