Plan a deck and generate Reveal.js HTML with tailored themes, multi-column layouts, callouts, charts, speaker notes, animations, and custom CSS. The workflow checks for slide overflow and reviews screenshots, while a browser editor lets you revise text without touching the markup. Presentations open without a build step; overflow checks and PDF export require the included Node dependencies.

Markdown Exporter works as an Agent Skill, a Dify plugin, or a Python command-line tool. It converts Markdown into formats including DOCX, PPTX, XLSX, PDF, HTML, Jupyter Notebook, CSV, JSON, XML, and language-specific code files, with processing kept local. Custom templates can style Word documents and PowerPoint decks. Slide conversion expects Pandoc-style presentation syntax, while spreadsheet and other table-oriented outputs are driven primarily by Markdown tables.

Use this Codex skill after a single-slide reference image has established the visual direction. It crops complex illustrations, icons, or maps that are impractical to redraw, while recreating titles, body text, cards, arrows, labels, and conclusion bars with editable PowerPoint objects. The workflow works page by page from individual PNG references and explicitly avoids placing the whole screenshot as a flat slide background, preserving editability where it matters.

SnapDeck drives a running web app with headless Chrome, captures real UI states, reads element coordinates, and renders HTML/CSS slide designs to PNG before assembling a full-bleed .pptx. It can reuse a logged-in session, open tabs or modals, force light mode, and place numbered callouts beside the right controls. The resulting slides are crisp picture slides for demos or training, not editable PowerPoint text and shapes.
