tycoslide

Create editable, on-brand PowerPoint slides from markdown, using your existing .pptx templates.

Getting started

1. Create a tycoslide theme. Install the create-theme skill (npx skills add tycoworks/tycoslide) and give an agent such as Claude Code or Codex your .pptx. You'll get back an npm package of mapped layouts, colors, and visual assets, like the tycoworks-theme.
2. Write slides in markdown. GitHub-flavored markdown is supported; see Markdown support below. tycoslide themes also include an agent skill, so an agent can write the slides for you.
3. Build. npx tycoslide build deck.md compiles the markdown into an editable PowerPoint file.

See it working

how-it-works.md is a deck about tycoslide, written against the tycoworks-theme. Clone the theme and build it:

git clone https://github.com/tycoworks/tycoworks-theme && cd tycoworks-theme
npm install
npx tycoslide build how-it-works.md

Markdown support

• Paragraphs, bullets and numbered lists, with bold, italic and links
• Tables
• Code, with Shiki syntax highlighting
• Mermaid diagrams
• Images, from the theme's asset catalog or a file path
• Speaker notes

Full syntax in syntax.md.

Requirements

Node 23.6 or later. Mermaid diagrams need Chrome on the machine; tycoslide finds an installed one, or run npx playwright install chromium-headless-shell.
