What is PPT Master?
PPT Master is an AI-driven application created by developer Hugo He and released as open source under the MIT license.PPT GenerationStandardized Workflow, currently at version v2.7.0. It is not a standalone SaaS service, but rather a set of structured workflows that run within an AI IDE equipped with Agent capabilities. Its core objective is to convert various types of document content intoNatively editable PPTX files, which completely resolves the pain point of traditional AI PPT tools generating “image-based PPTs” that cannot be edited element by element. The tool itself is completely free; users only need to cover the token fees for calling the AI model. Furthermore, with the exception of communication with the AI model, all processing is completed locally, ensuring data security and preventing data leaks.
Key Features of PPT Master
- All-in-One Document Parsing: Supports nearly 20 formats as input sources, including PDF, DOCX, XLSX, EPUB, HTML, LaTeX, web links, Markdown, and plain text.
- AI-Powered Outline Extraction: A foundational large language model automatically organizes the content’s logic, divides it into sections, extracts key points, and generates a presentation draft with a clear narrative thread.
- Native PPTX Rendering: Exports files in the standard Office Open XML format; all shapes, text boxes, charts, and vector graphics are native, editable objects.
- Compatible with Multiple Styles and Sizes: Includes over 20 professional templates covering mainstream scenarios such as MBB consulting, academic, and tech styles; supports over 10 canvas aspect ratios, including 16:9, 4:3, and vertical short videos.
- Custom Brand Templates: It can recognize and import existing PowerPoint templates from your company, automatically align them with brand style guidelines, and ensure a consistent visual style across your team.
- AI-Generated Images and Voice-Over Generation: Integrates AI-powered image generation capabilities to automatically match images to content, and can also automatically generate multilingual voice narration from presentation notes.
- Multi-ecosystem compatibility: Not tied to any single platform; supports major large language models such as Claude, GPT, and Kimi; compatible with various AI IDEs, including Claude Code, Cursor, and VS Code Copilot.
PPT Master's Core Technology
- Native DrawingML Rendering Engine: PPT elements are generated entirely based on the Office-standard DrawingML specification, rather than rendering pages as static images; all objects support native PowerPoint editing operations.
- 7-Step Standardized Workflow: Based on a 934-line, 100 KB SKILL.md rule file, the AI agent is driven to complete the full workflow—including content analysis, logical structuring, layout design, and element generation—according to a fixed process.
- SVG Intermediate State Conversion Mechanism: First, generate high-quality SVG preview files, then use a script to precisely convert them into native PowerPoint objects, balancing output quality, human preview, and script controllability.
- Three-Role Relay Scheduling Mechanism: By leveraging the collaborative efforts of the Content Analysis Agent, Design Agent, and Export Agent, we avoid the issues of illogical content and poor formatting that can arise from a single large language model.
- Local End-to-End Processing Architecture: The entire process—including document parsing, SVG generation, and PPTX export—is completed on the local device; only the model inference stage communicates with an external large model, thereby mitigating the risk of data leakage at the architectural level.
Use Cases for PPT Master
- Business Presentation Scenarios: Generate market analyses, strategic plans, and investment reports in the MBB consulting style, tailored to the frequent reporting needs of professionals in the finance and consulting industries.
- Academic and Research Settings: Directly convert your thesis PDF, experimental data, and project proposals into editable PowerPoint drafts for group meetings, grant defense presentations, and literature reviews.
- Corporate Office Scene: Batch-generate PowerPoint presentations for internal training and product introductions, automatically applying the company’s standardized brand templates to ensure visual consistency.
- Content creation scenarios: Quickly organize articles from official accounts, technical blogs, and Markdown notes into presentations, tailored for public speaking scenarios such as technical presentations and industry seminars.
- New Media Scenarios: Generates PowerPoint content directly in a 9:16 vertical aspect ratio, which can be exported as short-form video footage, tailored to meet the content publishing requirements of platforms such as Xiaohongshu and Douyin.
How do I use PPT Master?
- environmental preparation: Install Python 3.10 or later; Windows users must check the “Add to PATH” option.
- Project Deployment: Clone the project repository via GitHub
git clone https://github.com/hugohe3/ppt-master.git, go to the project directory and runpip install -r requirements.txtInstall the dependencies and make sure the project path consists entirely of English characters to avoid errors.
- Tool Configuration: Install an AI IDE with agent support on your local machine (we recommend Claude Code; Cursor and VS Code Copilot are cost-effective alternatives), and configure an API key for a large language model.
- introduction of material: Place the document files you want to convert in the project directory under
projectsin the folder.
- Instruction Generation: Enter a generation prompt in the AI IDE’s chat window—for example, “Please convert the reports in the ”projects’ directory into a 12-page MBB-style business presentation PPT”—and the AI agent will automatically handle the entire generation process.
- Export Edit: The generated PPTX file will be automatically saved to
exportsIf a folder contains SVG-format elements, simply select them, right-click, and choose “Convert to Shapes” to make all elements fully editable.
