Why MarkView?
Markdown is everywhere now. But sharing it with normal people? That's still a mess.
If you use AI coding tools like Cursor or Claude Code, your specs and documentation end up as .md files. Even regular ChatGPT users run into this—click that copy button and paste into a text file, and you've got Markdown whether you meant to or not. The format is everywhere now.
The problem comes when you need to share these documents. Send someone a .md file today, and they'll open it in Notepad. Headings look strange. Formatting codes are confusing. And tables? Completely unreadable—a grid of pipes and dashes that makes no sense to anyone.
There are tools that render Markdown beautifully, but none fit the everyday use case:
- Typora is excellent—but it's paid software. You can't expect friends or colleagues to buy an app just to read a document.
- VS Code, Obsidian, Notion—these are power tools for power users. Way too heavy for "just open this file."
- Online viewers require uploading your files to some website. Privacy nightmare.
There was no "Acrobat Reader for Markdown"—a simple, free, native app that anyone can install and use in seconds.
MarkView fills that gap.
It's a viewer, not an editor. Minimal, not bloated. Free, not paywalled. Built for normal humans, not developers. Designed to make AI-generated documents actually shareable.

Frequently Asked Questions
What is a Markdown (.md) file?
Markdown is a lightweight text format used for documentation, README files, AI chat exports, and notes. The file extension is .md. Tools like ChatGPT, Claude, Cursor, and Claude Code save documents as Markdown by default. Opened in Notepad it looks like text with stray symbols; opened in a Markdown viewer it renders into a clean, readable document.
How do I open a .md file on Mac?
Download MarkView for macOS (Apple Silicon or Intel) from the download section above, install the .dmg, then double-click any .md file. You can also drag a .md file onto the MarkView window. To make MarkView the default app for .md files, right-click any .md file in Finder, choose Get Info, expand Open With, select MarkView, and click Change All.
How do I open a .md file on Windows?
Download MarkView for Windows from the download section above. Both an .exe installer and an .msi package (for IT deployment) are available. After install, double-click any .md file or drag it onto the MarkView window. To make MarkView the default Markdown viewer, right-click any .md file, choose Open With, then Choose another app, select MarkView, and check Always use this app.
What is the best free Markdown viewer?
For viewing .md files rather than editing them, purpose-built viewers like MarkView are the lightest option — free, instant to open, no account required, and available for Mac, Windows, and Linux. Editors like Typora render Markdown beautifully but are paid. General-purpose tools like VS Code, Obsidian, and Notion can also display Markdown but are designed for power users and are overkill for someone who just needs to read a .md file shared with them.
Why do .md files look weird in Notepad?
Markdown files are plain text with formatting symbols like # for headings, * for emphasis, and pipe characters for tables. Notepad and other plain-text editors show those symbols literally, so headings, bold text, and tables appear cluttered and hard to read. A Markdown viewer like MarkView interprets those symbols and renders the document the way the author intended — with proper headings, formatted text, and readable tables.
How do I make .md files open in MarkView by default?
MarkView includes a built-in Set as Default option in its menu that handles this in one click on both Mac and Windows. You can also do it manually: on Windows, right-click any .md file, choose Open With, then Choose another app, select MarkView, and check Always use this app. On Mac, right-click any .md file in Finder, choose Get Info, expand Open With, select MarkView, and click Change All. After that, double-clicking any .md file will open it in MarkView automatically.
Is MarkView a browser extension?
No. MarkView (markview.io) is a native desktop application — you download and install it once on macOS, Windows, or Linux, and then double-click any .md file to open it in its own window. There is no browser involvement, no extension to install, and no internet connection required after install. Browser extensions for viewing Markdown also exist, but MarkView at markview.io is the desktop app described on this page.
Does MarkView work offline?
Yes. Once installed, MarkView runs entirely on your computer. Opening and rendering Markdown files does not require an internet connection, and your files are never uploaded anywhere. There are no accounts, no cloud sync, and no telemetry on file content — the only network activity is an occasional check for new versions of MarkView itself, which you can disable.
