RC Markdown

THE AI WORKFLOW COMPANION

Claude, ChatGPT, and other AI assistants produce detailed reports.
But when you open them on iPhone, LaTeX math breaks, Mermaid diagrams disappear, and code looks like a mess.

RC Markdown handles all of it. A dedicated viewer built to read, render, and share AI-generated documents exactly as intended.
