Introduction
Making a deck is hard. Making a beautiful one is harder. This article walks you through using ppt-master, an open-source skill, together with Claude Code and Codex, to turn an ordinary document into a natively editable slide deck complete with transition animations and even synthesized audio narration. You don't even need to prep your own material, just hand it a topic and you'll get a polished deck back.
If you've been hunting for a solid Claude PPT skill or Codex PPT skill, or you've searched terms like ppt master skill or html ppt skill alternative, this hands-on tutorial takes you all the way from install to finished deck.
The Designer's Dilemma: Why Beautiful Slides are a Universal Struggle
If you've ever built a deck, these scenarios will feel familiar.
- It's the night before a big presentation and you're staring at a blank slide, paralyzed by a blinking cursor and no clue how to start.
- You're on your eighth draft of a pitch deck. The ideas are solid, but the layout looks amateur—far from the "slick" finish investors expect.
- You can draft a 10-page report in no time, yet turning that same information into a compelling visual deck feels like an impossible task.
You're not alone. On Reddit, this kind of frustration is everywhere. Just a few thread titles capture the shared sense of helplessness:
"How the eff do you guys make so beautiful slides?"
—— r/consulting
"I don't hate making slides, I hate starting them."
"How do academics create beautiful presentation slides?"
AI is already powerful enough to handle plenty of everyday tasks, so why is making a deck still such a pain?
- Content Distillation — You have a massive doc or a broad topic, but you're not sure which points belong on a slide and which should stay in your speaker notes.
- Narrative Structure — You have all the pieces, but you lack a clear "red thread" or story arc to tie the slides together into a cohesive journey.
- Visual Execution — Even with the content ready, you struggle with the typography, spacing, and color palettes that give a deck that high-end, professional polish.
Those three hurdles are exactly what ppt-master aims to clear for you.
Real-World Case Studies
Talk is cheap, so this tutorial runs on a single real example throughout: I'll take one of my past articles, also the most popular on this site, Best PRD Skills Compared: 5 AI Tools for Writing Better PRDs, hand it to ppt-master, and turn it into a deck you could share as-is.
The reason I picked it is simple: it has a clear structure (five skills compared one by one, plus a selection table), which tests both the tool's ability to distill content and its ability to organize a narrative and make it beautiful. Every step below uses this article as the source material.
The second case comes later in the article.
What You'll Learn From This Article
- How do you install and configure ppt-master?
- How do you build a beautiful deck from existing material?
- How do you generate a beautiful deck from nothing but a prompt?
- When should you use ppt-master, and when should you reach for other tools?
What Is ppt-master
ppt-master (also written as ppt master or ppt master skill) is an open-source skill. In one sentence: feed it your raw material, and it generates a real PowerPoint.
- A real deck — what you get back isn't just "editable." It has PowerPoint's native transition and entrance animations, speaker notes that can be synthesized straight into audio narration, and it can even design against your own PPT template.
- Multi-format — beyond standard decks, it can produce social media assets, short-video cover images, Instagram Stories, and more.
- Data security: your files never leave your machine. Source docs are converted locally, SVGs are generated locally, and the PPTX is exported locally. The only external communication is the conversation between you and your AI editor, no different from your normal editor usage. No third-party server stores your source docs or output. For finance, government, and any organization with data-residency requirements, this matters a lot.
Crucially, ppt-master is a harness (a workflow framework), not a standalone agent. It orchestrates the entire deck-building pipeline, but the model you plug in defines the quality ceiling—think of it as harness + model = agent. For peak performance, I recommend pairing a large-context model like Claude with gpt-image-2 for image generation. While GPT, Gemini, and Kimi are perfectly capable alternatives, your mileage may vary when it comes to visual polish.
Capabilities & Limitations
To get the most out of ppt-master, it's helpful to understand its range across three key areas: input versatility, output flexibility, and the specific scenarios where it might not be the best tool for the job.
Inputs: Support for almost any source. Whether it's a PDF, DOCX, PPTX, EPUB, HTML, LaTeX, RST, Markdown, or plain text, ppt-master can digest it. It even supports web URLs and social media articles. If you're starting with nothing but a concept, the tool can trigger its own topic-research phase to gather context before it ever touches a slide.
Outputs: Beyond the standard 16:9. Thanks to its unique SVG → DrawingML pipeline, you aren't locked into traditional widescreen. You can specify various canvas formats directly in your prompt:
| Format | Ratio | Typical Use |
|---|---|---|
| PPT 16:9 | 16:9 | Business presentations, meeting reports |
| PPT 4:3 | 4:3 | Traditional projectors, academic defenses |
| Xiaohongshu | 3:4 | Image-text posts, knowledge posters |
| WeChat Moments / IG | 1:1 | Square posters, brand showcases |
| Vertical Story | 9:16 | Vertical stories, short-video covers |
| A4 Print | 1:√2 | Print posters, flyers |
Beyond basic shape-based PPTX files, it can export native chart/table objects or high-fidelity SVG snapshots on demand. Plus, it automatically backs up the raw SVGs, giving you the freedom to re-run and re-export without losing your work.
However, there are a few trade-offs to consider.
| Trade-off | The Details |
|---|---|
| Local Setup | This isn't a "plug and play" browser app. You'll need Python, the local repository, and an AI editor to get it running. |
| Generation Time | Expect a 10–20 minute wait for a 10-page deck. It processes slides serially to ensure design consistency—a far cry from the near-instant output of SaaS tools. |
| Collaboration | Since everything lives locally, you won't find real-time co-authoring or easy "share links" here. |
| No Visual Editor | While there's a browser preview with annotation support, edits are still AI-driven on the source SVG. It lacks the free-form, drag-and-drop canvas found in Gamma or Canva. |
The bottom line: If you're looking for zero-friction, browser-based slides in seconds, stick with Gamma or Canva. But if you value native editability, data privacy, and zero platform lock-in, ppt-master is a powerhouse worth exploring.
Getting Started: Initial Setup (Two Steps)
Step 1: Install Python (The Only Hard Requirement). You'll need Python 3.10 or higher. All other libraries can be installed with a single command.
I'll demonstrate using macOS and Linux. If you're on Windows, check out this Windows Installation Guide.
# macOS
brew install python
# Ubuntu / Debian
sudo apt install python3 python3-pip
Step 2: Clone the Repo & Install Dependencies.
The ppt-master repository is quite large (~670MB), so a standard git clone might be sluggish. I recommend downloading the source as a ZIP directly from GitHub for a faster start.
Visit https://github.com/hugohe3/ppt-master, click the "Code" button, and select "Download ZIP."
Unzip the folder locally. Open your terminal (or a modern alternative like Tabby), navigate to the ppt-master directory, and run:
cd ppt-master
pip install -r requirements.txt
Pro-tip: I use uv for lightning-fast Python package management, but pip install -r requirements.txt works perfectly for everyone else.
Once the dependencies are set, you just need a capable AI-powered IDE, like the Claude Code, Cursor, Trae, or VS Code with Copilot. Any tool that can read/write files and execute terminal commands will work as your "driver."
Unlocking Advanced Features (Optional)
This step is strictly optional. By default, ppt-master uses a zero-config web search to find images. However, if you want to automate high-quality AI image generation, you'll want to configure your .env file.
Open the project in your preferred AI editor (like Claude Code or Cursor). Copy the example config to create your .env file:
The .env file powers two major visual upgrades:
- AI Image Generation (
image_gen.py) — This allows the AI to dream up context-aware visuals in real-time. It’s the best way to get a cohesive "look." Here’s an OpenAI example:
IMAGE_BACKEND=openai
OPENAI_API_KEY=sk-xxx
OPENAI_MODEL=gpt-image-2
OPENAI_BASE_URL=http://127.0.0.1:3000/v1
Just swap in your own API key and endpoint details as shown below:
Supported backends include OpenAI, Gemini, Qwen (Tongyi), Zhipu, and more.
- Premium Stock Photo Search (
image_search.py) — While Openverse is free, it can be hit-or-miss. For a more "corporate-ready" aesthetic, plug in your Pexels or Pixabay keys:
PEXELS_API_KEY=your-pexels-key # Get one at: https://www.pexels.com/api/
PIXABAY_API_KEY=your-pixabay-key # Get one at: https://pixabay.com/api/docs/
With these set, the AI will automatically tap these capabilities to source or generate the perfect visuals for your slides. If you’re in a rush, feel free to skip this and come back later.
Workflow Case 1: Turning a Document into a Professional Deck
Let’s get to the main event. We’re going to take a raw document and turn it into a structured presentation. It’s a simple three-step process.
Step 1: Add Your Source Material to /projects
Take your source document like my popular PRD Skill Comparison article—and export it as Markdown or PDF. Drop it into the projects/ folder within the ppt-master directory.
Step 2: Prompt the AI to Generate the Slides
In your AI editor (like Claude Code), simply type:
"Generate a full slide deck based on '5 Best PRD Skills Compared'. Include 3 images: one for a high-impact cover and two for the body slides."
ppt-master handles the heavy lifting immediately: reading the source, distilling the key points, and drafting a logical narrative. This instantly solves the "blank page" problem.
Step 3: Review the Design Specification
Before the AI starts "drawing" the slides, it will present a brief design strategy for your approval:
The tool intelligently suggests:
- Aspect Ratio: 16:9 widescreen (standard) or others.
- Target Audience: Who is this for? (e.g., Technical Stakeholders).
- Tone & Style: Professional, minimalist, or high-energy.
- Visual Language: Suggested color palettes, typography, and iconography.
Step 4: Watch the AI Build Your Deck
Once you greenlight the plan, the AI takes over the end-to-end production: content analysis → layout design → SVG generation → quality checks → speaker notes → PPTX export.
It processes the slides serially (one by one) to ensure that the colors, fonts, and "vibe" remain consistent throughout the entire deck. For a 10-slide presentation, this takes about 15 minutes.
Bonus: You can even request a 9:16 vertical version for mobile sharing or social media.
Real-Time WYSIWYG Preview
The generation process isn't a "black box." ppt-master launches a local web server (usually at http://localhost:5050) so you can watch the slides appear in real-time.
The preview portal offers three powerful features:
- Live Rendering: See exactly what each slide looks like as it’s built.
- Direct Manual Tweaks: Don't like a specific font size or color? Click any element to adjust it manually in the side panel. Hit Apply Changes, and it writes directly back to your source files.
- AI Annotations: For bigger changes (like "make this section more visual"), just select the area, add a note, and hit Submit Annotations. The AI will then re-generate that specific part for you.
Understanding the Output: What’s in the Box?
When the workflow finishes, you’ll see a summary in your terminal:
All your files are organized within a timestamped folder under projects/. Here is the breakdown:
| Directory | What's Inside |
|---|---|
sources/ |
Your original docs and the AI-processed Markdown versions. |
analysis/ |
Machine-extracted facts (image analysis, PPTX structure, etc.). |
images/ |
The unified image pool: user images, extracted images, web images, AI-generated images, etc. |
svg_output/ |
The AI's hand-written raw SVG (author source, the only manually editable directory). |
svg_final/ |
Self-contained SVGs derived fromsvg_output/ to serve the preview. |
live_preview/ |
Preview service state, direct-edit history, annotation logs. |
notes/ |
Speaker Scripts: total.md contains your full presentation script. |
exports/ |
The Final Deliverable: Your natively editable .pptx file lives here. |
backup/<timestamp>/ |
Thesvg_output/ snapshot frozen at export time, for easy rebuilds. |
Pro-tip: Most users only need the .pptx in exports/ and the script in notes/.
Congrats! You've just automated your first professional deck. Now, let’s look at a "Zero-to-Hero" scenario.
Workflow Case 2: From "One-Sentence Prompt" to Presentation
What if you don't have a document at all? Say you need a quick briefing on a trending topic. Such as the 2026 World Cup performance of the Cape Verde national team.
You can simply give ppt-master a prompt. The skill will:
- Perform Automated Research: Search the web for facts and data.
- Synthesize Content: Build a narrative from scratch.
- Generate Visuals: Source or create relevant images.
The result is a comprehensive first draft that would have otherwise taken hours of googling and manual formatting.
The Verdict: AI as Your Design Partner
Creating a high-stakes presentation is a marathon. ppt-master handles the "boring" 90%: research, distillation, and layout—so you can focus on the "creative" 10%.
As the developer puts it:
"AI is your designer, not your finisher. The output is a high-fidelity design draft, not a locked file. Use it to eliminate the 'blank page' anxiety and give yourself a professional foundation to build upon. Your taste and judgment are still the secret sauce."
FAQ: Frequently Asked Questions
Q: Do I need to be a developer to use this?
Not at all. You just need to do three things: install Python, prepare an AI IDE, and drop your material into the projects/ directory. The rest happens through conversation with the AI. No coding is required for daily use.
Q: Does ppt-master generate images or a real deck?
A real deck. Every shape, text box, and chart it outputs is a native DrawingML object. You can change colors, fonts, and data directly in PowerPoint, Keynote, or Google Slides—it’s not just a pasted image.
Q: Which input formats does it support?
PDF, DOCX, PPTX, EPUB, HTML, LaTeX, RST, Markdown, plain text, plus web links, WeChat articles, and more. When you only have a topic and no document, it can gather material online first.
Q: Can it only make 16:9 decks?
No. It can also produce 4:3, Xiaohongshu 3:4, WeChat Moments 1:1, vertical 9:16 Story, A4 print, and more. Just specify the format in the conversation.
Q: How long does it take to generate a deck?
Typically 10–20 minutes for a 10-slide deck. Going page by page ensures consistent color, fonts, and rhythm across the whole deck. For faster results, consider a more capable model.
Q: Do I have to use Claude? Will other models work?
Not required. For the best results, a large-context Claude + gpt-image-2 is recommended. GPT, Gemini, Kimi, and others can complete the flow too, though layout precision and visual quality may vary—the harness sets the floor, while the model sets the ceiling.
Q: Can I use it without an image-generation API key?
Yes. There is a zero-config web image search as a fallback by default. Configuring AI image generation or Pexels/Pixabay is strictly optional to enhance image quality.
Q: Will the generated deck open properly in WPS or Keynote?
Yes. The output is a standard .pptx, so PowerPoint, Keynote, WPS, and LibreOffice can all open it. Entrance animations render most faithfully in PowerPoint 2016+ and Keynote; older versions may downgrade some effects to "Appear."
