Your Mac, iPad, and iPhone still open .md as raw text.
Marko fixes that.

Every AI tool answers in Markdown now, from ChatGPT and Claude to your coding tools. Marko is the free, native viewer that renders it properly, with real typography, tables, diagrams, and math, and reads it aloud to you. Fully offline.

Document Intelligence

Understand a document without leaving it.

Summarize what you’re reading. Ask a question about it. Select a passage and have it explained. It all runs on device, so your document never leaves it.

Summarize

Ask questions

Explain a selection

Explain a diagram

Needs a device with Apple Intelligence. Explaining diagrams needs iOS 27 or macOS 27. Everything else runs on any Mac, iPad, or iPhone.

Marko on a Mac with the Document Intelligence panel open beside a document. The panel shows a summary of the document and a list of its key points.

Fold-aware reading

Made for the iPhone Duo.

On the Duo’s inner display the outline can sit beside the page. Bend it partly open and the outline fills one side of the fold and the page the other, so the hinge never cuts through the text. Closed, Marko reads like it does on any iPhone.
