Open any .md from Files, Mail, or another app and read it the way it's meant to look: real typography, code, tables, Mermaid, and math. Fully offline, on-device AI.
Marko is a fast, native Markdown viewer for iPhone and iPad. Open any .md file and read it the way it was meant to look, with real typography, syntax-highlighted code, GFM tables and task lists, Mermaid diagrams, and KaTeX math. Everything renders on your device with no network access, so your documents never leave it.
Marko is a viewer, not an editor. It never changes your files. Open Markdown straight from the Files app, or share it in from Mail, Safari, or any other app, and read it full-screen with an outline, find in page, and adjustable text size.
It is built for the Markdown you didn't write by hand, too: the .md that AI assistants and coding agents produce, generated READMEs, and agent output.
DOCUMENT INTELLIGENCE, ON DEVICE
