PPT Master — AI-Powered Native PowerPoint Generation

Introduction

PPT Master is an open-source Python tool that uses AI to convert documents or topics into real, native PowerPoint presentations. Unlike screenshot-based or image-only slide generators, it produces .pptx files with editable shapes, transitions, animations, data-backed charts, and optional audio narration from speaker notes.

What PPT Master Does

• Generates native .pptx files with editable text, shapes, and layouts
• Creates data-driven charts and tables from structured input
• Adds slide transitions and element animations automatically
• Produces audio narration from speaker notes using TTS
• Supports custom .pptx templates for brand consistency

Architecture Overview

PPT Master is a Python application that combines LLM-based content generation with the python-pptx library for native PowerPoint file creation. The pipeline works in stages: content planning, slide layout selection, element placement, chart generation, and optional audio synthesis. Each stage is modular, allowing you to customize or replace individual components.
