GitHub Flavored Markdown

Give the details some structure.

Mermaid diagrams

See how it all connects.

Follow the architecture in a plan or the flow behind an explanation. Markitown renders supported Mermaid diagrams right inside the Markdown your agent creates.

Diagram source stays in the Markdown.

Accessibility, by design

Markitown. For everyone.

Care in the details. Choice in how you read. We’ve put thought into how Markitown works with Apple’s accessibility features, so more people can read, navigate and work with their documents.

A free document checker helps you find accessibility issues in your Markdown. The full version adds tagged PDF and semantic HTML export. Read the accessibility statement

Seven accessibility features declared in App Store Connect

VoiceOver: Read and navigate your documents with Apple’s screen reader.
Voice Control: Use your voice to navigate and interact with the app.
Larger Text: More room for reading, with larger text on iPhone, iPad and Apple Vision Pro.
Dark Interface: A dark appearance when that is the way you prefer to read.
Sufficient Contrast: Text and controls designed to stay clear against their backgrounds.
Differentiate Without Color Alone: Meaning that does not depend on color alone.
Reduced Motion: Respects your preference for less motion and animation.

Markitown has been reviewed by Apple. These are its current accessibility declarations in App Store Connect, not an independent certification. Six features are declared across iPhone, iPad, Mac and Apple Vision Pro. Larger Text is declared for iPhone, iPad and Apple Vision Pro; no Mac declaration is currently recorded.

Search & replace

Find the word. Refine the thought.

Find text for free, with regular expressions when a simple word search is not enough. Unlock the full version to replace matches and refine your document precisely.

Find—including regex—is free. Replace and Replace All require the full version.

Native file storage

At home in your own folders.

Open documents from Files, the Finder or iCloud Drive. No import ritual. No proprietary library. Just Markdown, in the locations you choose.

The same ordinary files remain usable with your agents and your other tools.

Auto-save. Stay with the thought.: Native document auto-save takes care of saving your edits as you work, so you can stay with the idea in front of you.
Continuity. Follow the idea.: Start on your iPhone, continue on your iPad and finish on your Mac with Handoff. Keep the document in iCloud Drive and open it on Apple Vision Pro, too—your same Markdown, in a whole new workspace.
Your files. Your Time Machine backup.: On Mac, documents in locations included in your Time Machine backup can be restored with Time Machine. Your Markdown stays an ordinary file, not locked inside an app library.

Handoff requires compatible iPhone, iPad and Mac devices, the same Apple Account, Wi-Fi, Bluetooth and Handoff enabled. Vision Pro access here uses iCloud Drive, not a native Handoff transfer. iCloud availability and Time Machine recovery depend on your settings and existing backups. Editing requires the full version of Markitown.

100% native. No Electron inside.

Not a web app dressed up in Electron. Markitown is 100% native, built with SwiftUI, UIKit, AppKit and TextKit 2, taking advantage of modern APIs in Apple’s 26 and 27 releases. Engineered for responsive performance and careful use of memory and system resources, even with very large documents—so those resources go into your work, not the wrapper.

Edit your documents in spatial computing

Your ideas. A whole new dimension.

Move beyond the edge of a screen. On Apple Vision Pro, give each document its own native window. Keep a plan beside your research. Bring the draft into view. Open more documents as your workspace grows.

As many document windows as you need, within available system resources. No fixed numerical window limit is published by Apple. Reading is free; editing requires the full version of Markitown.

Prefer a screen? Keep documents side by side on Mac and iPad, too.

iPhone Duo

A bigger canvas. Still in your hands.

An adapted workspace makes room for the larger inner display. Your documents feel at home here, too.

Share with the full version of Markitown

From agent output. To a shared document.

Turn a Markdown plan, report or technical explanation into PDF or HTML, or print a copy. Share the result without asking everyone to use the same app.

Type & spacing

Give your eyes a little more room.

Adjust text size and spacing on supported platforms. Find the reading rhythm that works for you, from a short note to the long read.

Writer Mode. When you write at the end of a document, keep the line you’re typing just below the middle of the visible editor—not pressed against the bottom edge. Part of the full version of Markitown. Line numbers. Show optional line numbers in the left margin on Mac, iPad and Apple Vision Pro. Keep your place, or point someone to the exact line.

Mac command-line tool

From your terminal. Back to your agent.

Open a Markdown plan from Claude Code, Codex or any command-line agent that can run a local command. Read it as a document. Refine it with the full version.

Use --wait for an editor handoff: save your changes, then close the document window to return control to the terminal. For tools that honor $EDITOR, make Markitown your editor.

Mac only. Separate CLI installation required. Free to read; the full version of Markitown to edit. Markitown edits your documents—it does not run AI agents or connect to models.
