Whitedeck is a TypeScript CLI that converts markdown into Apple Keynote-style slides (HTML, PDF, editable PPTX, and .key) using exact geometry extracted from Keynote's White theme. It is designed as a Claude skill with an opinionated editorial persona to produce clean, content-first decks. The project stands out for its provably exact layout geometry and multi-format output, though its audience is niche.

Target audience: AI agent users, developers, and presenters who want clean, Keynote-style decks from markdown
