MaraudersPPT — Turn Markdown into Presentation-Quality Slides with AI
Let's be real: making slide decks is tedious. You write the content in Markdown, then spend hours wrestling with PowerPoint layouts, font sizes, and chart formatting. What if your AI could handle all of that — and produce slides that actually look professional?
MaraudersPPT is a Claude Code Skill that converts your Markdown documents into presentation-quality .pptx and .pdf slides. And when I say presentation-quality, I mean McKinsey/BCG-level design — no rounded cards, no gray backgrounds, no "AI dashboard" aesthetics.
How It Works
You write your content in Markdown. The skill maps it to slides automatically:
- H1 headings become title slides
- H2 headings become section dividers
- H3 headings become sub-headers
- Lists, tables, code blocks, and images are mapped to the most appropriate layout
The skill supports 23 different layout types covering text, tables, code, images, lists, KPIs, charts, timelines, process flows, comparisons, and more.
Design Specs
Every slide is rendered at 1920x1080px (16:9) with strict design rules:
- Clean white background (#FFFFFF) with black text (#1A1A1A)
- Accent red (#D94F4F) used sparingly for bold emphasis only
- 8px grid-based spacing throughout
- Minimum 16px font for content
- Max 1-2 topics per slide, 3-4 bullet points optimal
- Full CJK/Korean font support via Pretendard with proper fallback chains
Auto-Generated Charts
The skill includes 8 chart templates that render automatically from your data:
- KPI Cards
- Bar Charts
- Donut Charts
- Process Flows
- Timelines
- Comparison Tables
- Icon Grids
- Funnels
For decks with 10+ slides, an executive summary slide is auto-generated.
Language Preservation
One detail I'm particularly proud of: the skill preserves your source language. Korean Markdown produces Korean slides, English Markdown produces English slides. No unwanted translation. Full CJK support.
The Pipeline
Under the hood, MaraudersPPT runs a 5-wave parallel execution pipeline:
- AI image generation
- Chart rendering
- Slide layout creation
- PDF rendering (via Playwright)
- Quality assurance checks
All running concurrently for speed.
What's New (v1.3.2 — Feb 2026)
Recent updates have been all about quality and reliability:
- Google Antigravity Support: Added as a supported native image generation environment
- Hard Quality Gates: Stricter validation for visual coverage and markdown sanitization
- Anti-Truncation: Explicit prohibition on content truncation with rewrite mandates
- Deterministic Mapping: Tightened prompt contracts for consistent slide mapping
- 5 New QA Checks: Deduplication, URL handling, H3 mapping improvements
Getting Started
Invoke the skill in Claude Code with the MaraudersMD2PPT keyword. Point it at any Markdown file and watch it work.
The output lands in a clean structure:
docs/
original_pptx/
v1.0_original.pptx (editable)
v1.0_original.pdf (primary output)
assets/ (charts, generated images)
Why You Should Try It
If you're tired of the Markdown → PowerPoint dance, this skill eliminates it entirely. Write your content once, get professional slides out. The design quality is genuinely impressive — these aren't generic AI-generated slides with clip art and gradients. They're clean, structured, and presentation-ready.
