Markdown often contains private ideas, client work, product specs, research, and AI output. markup is built for people who want beautiful previews without making upload-to-render the default.
Your Markdown, filenames, diagram definitions, and math source are not sent to external rendering servers. There is no upload-to-render workflow, and anonymous rendering statistics stay off unless you explicitly turn them on.
A bundled local rendering engine handles Markdown, syntax highlighting, LaTeX math, Mermaid diagrams, and supported PlantUML diagrams on your device, so supported diagrams render locally even when external rendering services are unavailable.
GitHub Flavored Markdown, callouts, task lists, drafts, notes, documentation, and AI-generated Markdown can all move from rough text to a polished preview without changing your writing workflow.
Native rendering, landscape Reading Mode, dark mode, and a battery-conscious preview engine are tuned for repeated mobile use, so long Markdown documents remain comfortable to review.
Choose from 9 body fonts, 7 code fonts, and multiple syntax themes, then export polished previews to PDF when you are ready to share.

markup's callout boxes and mermaid diagram support make it indispensable. I can create comprehensive documentation with attention-grabbing notices and clear flowcharts, all rendered beautifully.

When working with ChatGPT or Claude, markup is my go-to previewer. It perfectly renders the AI-generated Markdown content, making it easy to review and refine outputs before sharing with clients.
