I tested twelve markdown editors over the past month. Some I'd used before, some were new to me. I looked at speed, features, offline support, export options, and whether they respected my privacy. Here's what I found.
What I Was Looking For
Before getting into the list, here's my criteria. I wanted an editor that loads fast — under two seconds. I wanted live preview because I like seeing what I'm writing. Offline support was important because I work from coffee shops with terrible WiFi sometimes. And privacy matters to me — I don't want my documents sent to someone else's server.
I didn't care about collaboration features, team accounts, or cloud sync. If you need those, Notion or Google Docs handle that better anyway.
1. MDtoTEXT — Best for Quick Edits and Privacy
Full disclosure: I built this one, so I'm biased. But I built it because I couldn't find something that checked all my boxes. It loads instantly, works offline as a PWA, has live preview, dark mode, auto-save, Mermaid diagrams, LaTeX math, and syntax highlighting. Everything runs in your browser — zero data leaves your machine.
If you want something that opens and works without any setup, this is it. Try it here.
2. VS Code — Best for Developers
If you already write code in VS Code, you don't need a separate markdown editor. The built-in markdown preview is actually really good. Hit Ctrl+Shift+V and you get a live preview that updates as you type. With extensions like Markdown All in One and Paste Image, it becomes a powerful editing environment.
The downside is that VS Code is overkill if you just want to write a quick note. It's a full IDE. It takes a few seconds to launch and uses a lot of memory. But for serious documentation work, it's hard to beat.
3. Obsidian — Best for Note-Taking and Knowledge Management
Obsidian has become incredibly popular and for good reason. It's a markdown-based note-taking app with a graph view that shows connections between your notes. The plugin ecosystem is massive — there are plugins for Kanban boards, calendars, daily notes, even a plugin that turns Obsidian into a full publishing platform.
It's free for personal use. The sync feature costs money ($5/month) and the publish feature is $10/month, but the core app is completely free. If you're building a personal knowledge base, this is probably the best option.
4. Typora — Best for Distraction-Free Writing
Typora does something different — it hides the markdown syntax. You see bold text as bold text, not as **bold text**. The markdown is there underneath, but the interface shows you the formatted result. It's incredibly clean and minimal.
It costs $15 (one-time, no subscription) and works on Mac, Windows, and Linux. The downside is that it's not open source and development slowed down for a while (though it has picked up again recently).
5. iA Writer — Best for Focus
iA Writer is the gold standard for minimalist writing. It has a focus mode that highlights the sentence or paragraph you're currently working on and dims everything else. The typography is beautiful and the export to DOCX and PDF is the best of any markdown editor I've tested.
It's pricey at $30 for desktop and $20 for mobile. But if you do a lot of long-form writing, the focus mode genuinely helps.
6. Notion — Best All-in-One (But Not Pure Markdown)
Notion deserves a mention even though it's not a pure markdown editor. It supports markdown shortcuts — type / and you get a menu, type # and it becomes a heading. Under the hood it uses a block-based system, not markdown files.
The problem is portability. Exporting from Notion to markdown is messy. You lose some formatting, images get weird, and the output needs manual cleanup. I use Notion for project management but I never write long documents in it.
The Comparison Table
Here's a quick overview of how they stack up on the things I care about:
MDtoTEXT — Free, instant load, PWA offline, live preview, diagrams, math, zero tracking
VS Code — Free, fast but heavy, offline, great preview, needs extensions, Microsoft telemetry
Obsidian — Free, moderate load, offline, plugin-based preview, local files only
Typora — $15, fast, offline, seamless preview, no tracking
iA Writer — $30, fast, offline, focus mode, beautiful export
Notion — Free tier, web app, slow for large docs, limited offline, not real markdown
Which One Should You Pick?
If you want something that just opens and works without any setup or tracking, MDtoTEXT. If you're already in VS Code, use that. If you're building a knowledge base, get Obsidian. If you write for a living and want the best typing experience, try iA Writer or Typora.
The good news is that most of these are free or cheap, and they all produce standard markdown files. You can switch between them anytime without losing anything. That's the whole point of markdown.
