PrettyMD vs MarkText
MarkText is one of the most-loved free Markdown editors on GitHub. It's also built for a job most vibe coders don't do by hand anymore: writing. Here's the honest comparison for people whose agents do the writing.

The 60-second answer
If AI agents write your specs, plans, and docs, PrettyMD is the tool for what happens next. It opens a folder of .md files with zero ceremony, highlights exactly what changed since you last read each one, and turns your feedback into line comments that Claude Code, Codex, opencode, or Cursor read directly and act on. MarkText has no agent integrations, no comment loop, and no sense of what you've already read — it's an editor, and the reading problem it was never designed to touch is now the daily bottleneck.
If you still write Markdown by hand and want a beautiful, free editor, MarkText is genuinely great. It's MIT-licensed open source with 60,000+ GitHub stars, real-time WYSIWYG rendering, focus and typewriter modes, and Linux support that PrettyMD doesn't offer. Free is free — that matters, and we won't pretend otherwise.
Feature-by-feature: the details that matter
| Capability | PrettyMD | MarkText |
|---|---|---|
| Line comments your AI agent reads | PMD Highlight → sidecar comment → compatible agent updates the Markdown | None — single-player editor |
| Change tracking since last read | PMD Automatic per-file highlights | None — no read-state memory |
| Agent integrations | PMD Claude Code, Codex, opencode, Cursor | None |
| Folder-wide review reading | PMD Folder-scoped .md sidebar + tabs | Opens files or folders for editing |
| WYSIWYG editing | Read-only by design | MT Real-time, live-preview editing |
| Price | $19 one-time after 7-day trial | MT Free, MIT open source |
| Linux support | No | MT AppImage, deb, rpm, snap, Flatpak, AUR |
| Mermaid, code, full CommonMark spec | Yes | Yes |
| Themes & focus mode | Light/dark themes, focus mode, keyboard-first | Themes, focus & typewriter modes |
1The agent comment loop — feedback without leaving the page
Your agent produces a migration plan. You disagree with step 3. Highlight it, type why, done — Claude Code picks up the comment in context and revises. The conversation lives inside the document, where the work lives.
You'd copy the section into your terminal or chat window, explain which file and which part, and manage the exchange by hand. MarkText has no integration surface for coding agents — that's not a flaw, it's just not what it was built for.
2Change tracking — attention where it's needed
Agents revise constantly. PrettyMD highlights every line that changed since your last read, so a revised 500-line spec costs you 40 lines of attention instead of a full re-read.
MarkText doesn't track your reading. A file your agent rewrote overnight looks exactly like one you've read ten times — the only way to find what changed is to re-read or open a diff tool manually.
3Reading a folder of agent output
Point it at your project folder. Every .md file renders instantly — Mermaid diagrams, code blocks, tables — in a reading view with outline, tabs, and search. No project files to create, no settings to configure before the first useful read.
MarkText opens the same files, but every pane is an editing surface. Reading is possible; it's just not the center of gravity. For a document you'll never edit — which is most agent output — the editing chrome is overhead.
4Where MarkText genuinely wins
Credit where it's due:
Free and open source. MIT-licensed, no cost at any tier, community-funded through Open Collective and GitHub Sponsors. If your budget is $0, MarkText is a legitimate answer.
A genuinely pleasant WYSIWYG editor. Real-time preview while you type, focus and typewriter modes, theme support. As a hand-writing tool it's among the best free options anywhere.
Linux. AppImage, deb, rpm, snap, Flatpak, and AUR packages. PrettyMD is desktop Mac/Windows only today.
Should you switch from MarkText to PrettyMD?
Only if your bottleneck has moved from writing to reviewing. MarkText assumes you are the author. PrettyMD assumes an agent is the author and you are the reviewer — a different job that needs comments the agent can read and a memory of what you've already read. Plenty of people keep both: MarkText for the docs you write, PrettyMD for everything your agents produce.
Which should you choose?
Choose PrettyMD if…
- Claude Code, Codex, or Cursor writes docs you must review
- You want feedback delivered as line comments the agent actually reads
- Revised files should show you what changed, not make you hunt
- You want to open a folder and start reading — no setup ritual
Choose MarkText if…
- You write Markdown by hand and want a free, polished editor
- $0 budget is a hard requirement
- You're on Linux
- You live in WYSIWYG editing, not review loops
Frequently asked questions
Is PrettyMD a good MarkText alternative?
For reading and reviewing Markdown that AI coding agents write, yes — no setup, automatic change highlights, and line comments that agents read and act on. MarkText stays the right pick if your job is hand-writing Markdown for free.
Is MarkText free?
Fully. MIT-licensed open source, no paid tier, no subscription (checked August 2026).
Is MarkText still maintained?
Development is active on the develop branch with a v0.20.0 release candidate (July 2026), but the latest stable remains v0.19.1 (June 2026), and stable releases have historically lagged the branch. Check the repo before relying on it.
Can MarkText leave comments for AI coding agents?
No. MarkText has no agent integrations and no comment loop — feedback means copy-paste into your chat or terminal. PrettyMD ships that loop as its core feature.
