Mac App Store · Windows coming soon

Three ways to write. One window.

WYSIWYG, hybrid live-preview and raw markdown: the same document, one keystroke apart. Diagrams, maths and export to anything, with nothing to install.

Markdown became the format everything speaks: every README, spec, agent skill and LLM export is a .md file. The editors for it are either abandoned, built for something else, or fifteen dollars. Marko is the maintained one.

Coming soon to the Microsoft StoreWindows 10 and 11. $9.99 once, same as the Mac.

Why now

Markdown is the lingua franca of AI. It deserves a real editor.

Every CLAUDE.md, agent spec, model output and README is markdown. It is the format we now think in, and the tooling never caught up. Word and VS Code are the wrong shape for a document. A plain text editor is the right shape and no help at all.

The free editors that tried are mostly gone: MarkText last shipped a stable release in 2022, MacDown in 2020. Obsidian absorbed the refugees, but it is a second brain, not a document editor. Typora is good, actively maintained, and $14.99.

Marko is the maintained middle: a document-first editor that costs $9.99 once and does not want to own your files.

Three ways to write

One document. Three ways to write.

WYSIWYG hides the formatting symbols, Notion-style. Hybrid gives you Typora-style live preview with the syntax still visible. Raw is plain markdown when you want full control. Flip between them with ⌘1 / ⌘2 / ⌘3, with no mode switcher to fight, no preview pane to babysit. Find and replace, source line numbers and the table tools work the same way in all three.

WYSIWYG mode: the document rendered with the markdown symbols hidden — WYSIWYG

Hybrid mode: headings and emphasis rendered while the markdown symbols stay visible — Hybrid

Raw mode: the same document as plain markdown source — Raw

Themes

Thirteen themes. Pick your mood.

Marko Light/Dark, Sepia, Nord, GitHub, Solarized, Dracula, Tokyo Night, Gruvbox, Rosé Pine, Everforest, Catppuccin Mocha, plus drop in your own CSS. Fifteen fonts ship with the app, or pick any font already installed on your Mac and save the pairings you like.

What it does

Everything you reach for, in one window.

Diagrams from text

Mermaid flowcharts, sequence and gantt diagrams, rendered live as you type, in every mode.

$KaTeX math rendered in Marko$

Math, beautifully typeset

Inline and block equations via KaTeX, set naturally in the page.

Tables that behave

A layout solver, drag-to-resize columns, and widths that survive a round trip through markdown and out to PDF.

Export anywhere

PDF (with bookmarks), Word, OpenDocument, EPUB, LaTeX, MediaWiki. Pandoc is bundled, zero setup. Import the same formats back. Print, too.

Distraction-free writing

Focus mode dims everything but the current block; typewriter mode keeps your line centered.

Typography that ships with the app

Fifteen bundled fonts, one-click pairings, and any font you already own. No theme-hunting required.

Why I built it

Death by a thousand paper cuts.

Marko started as a pile of small frustrations. Writing markdown was fine; everything around it was broken. I wanted to sketch a Mermaid diagram and actually watch it render. Pull a table out of a PDF, or hand a clean Word file back, without a detour. Build a table without counting pipes by hand. Just preview formatting as I typed: fast, snappy, no lag. No single tool did all of that well, and stitching five together was its own kind of misery.

So I built the one I had been wishing for. That was June; it has shipped steadily since, and the things I learned from the editors that died (silent data loss, quiet abandonment, performance rot) are the things I am most careful about.

And Typora? Solid app, but it's a $14.99 ask, and I figured I could just build the one I actually wanted. So I did.

Origin story

It started as a weekend project.

The first version went from empty folder to working app in two days, in June 2026. That is still the honest story of how this began; it just is not the headline any more. What matters now is that it kept shipping.

Want to know when it lands?

Leave your email and I'll write the day Marko is on the Microsoft Store.

One email, when Windows ships. Nothing else, and nothing about the Mac version.

Pricing

$9.99 once. Not $14.99.

Same price I promised during the beta.

On the Mac App Store

$9.99 once, not a subscription. You get every feature. There is no pro tier.

Every 1.x update

Included. They come through the App Store and you never pay for them.

If you help me test it

File a bug or a feature request during the beta and 1.x is free for you, permanently. That is the whole deal.

Builds you already have keep working. Nothing gets switched off retroactively. Marko is made by Aditya Gupta. The Mac App Store version is sold by Aditya Gupta; direct downloads come from Adya Services Ltd.

Questions

The three things people ask.

Why is it 108 MB? Is this an Electron app?: It is. That 108 MB is the Mac App Store download, and most of it is Pandoc, the bundled conversion engine. That is the trade: the download is fat so that exporting to DOCX, EPUB or LaTeX needs no installs, no Homebrew, and no "please install Pandoc first" dialog. Typora asks you to install Pandoc separately. Marko does not.
macOS only?: For now. A Windows version is in Microsoft Store certification, for Windows 10 and 11 at the same $9.99. I can't give you a date because Microsoft decides how long that takes. Leave your email in the box above and I'll tell you when it's out. On the Mac, it needs Apple silicon.
Where do my files live? Do you see anything?: They live wherever you saved them, as plain markdown. There is no account, no vault, no sync, and the app sends nothing anywhere: turn your Wi-Fi off and it behaves identically. The website has analytics; the editor has none.
