A markdown note is just a text file with a few punctuation marks — # Heading, **bold**, - a list — that any app, on any device, in any decade, can open. That is the whole pitch. When your notes are plain-text markdown, no single company owns them, and "switching apps" means dragging a folder, not begging an exporter to give your work back.
That single property — portability — is why markdown people care about markdown at all. So the right question isn't "which app has the prettiest markdown editor," it's "which app keeps my markdown mine." Some store real .md files on disk; others just render markdown syntax while locking the actual text in a proprietary database. That difference matters more than any feature.
Why markdown means no lock-in
Lock-in is what happens when leaving an app costs you your notes. Proprietary formats create it by design: your writing lives in a database only that app can read, and the "export" is often a lossy afterthought. Markdown breaks the trap three ways:
- It's readable without the app. Open a
.mdfile in TextEdit, VS Code, or a terminal and it's all there — no app required, ever. - It's future-proof. Plain text has outlived every notes app so far and will outlive the current ones. A 2005 text file still opens today.
- It's portable between tools. The same folder of files works in Obsidian, iA Writer, or a plain editor, so you can change your mind later. That freedom is the backbone of a durable personal knowledge management system.
The catch: markdown-rendering is not the same as markdown-storage. If an app shows you markdown but keeps the source in its own database, you get the syntax without the escape hatch. Always check whether you can find real .md files on disk.
The shortlist
We make one of the apps below, so we'll name the bias and keep the table honest — each pick is the one we'd send a friend to for that need.
| Your situation | Start with | Markdown model |
|---|---|---|
Local .md files, linking, full control |
Obsidian | Real files on disk — the Zettelkasten power tool (vs Notion) |
| Beautiful markdown writing on Apple devices | Bear | Markdown editor; exports clean .md and PDF |
| Outliner-style, open-source, privacy-first | Logseq | Plain markdown files, block-based |
| Distraction-free long-form drafting | iA Writer | Pure .md files, nothing else |
| Fast private capture on iPhone, AI across your notes | Clair Mind | Not a folder of .md files — but plain-text export, offline, on-device |
Where each one actually wins
Obsidian is the honest default for markdown purists: a folder of files you own outright, with backlinks and a graph on top. It's a desk you sit down at, not a pocket tool.
Bear and iA Writer are for people who mostly write — Bear if you want polish and organisation, iA Writer if you want a blank page and nothing else. Both hand you clean markdown on the way out.
Logseq suits outliners and tinkerers who want an open-source, block-based tool over local files.
And the honest limit of ours: Clair Mind is not a strict folder-of-.md-files app, so if editing raw markdown files across devices is your non-negotiable, pick Obsidian. Where it fits instead is the moment those desk apps miss — a thought evaporating while you're standing in line. It's built for one-tap capture, offline and private, with connections and AI answers across your own notes, and it exports to plain text so you're never trapped. If you want the same idea without leaving your files, that's exactly the Obsidian workflow.
How to choose in one step
Open your top candidate, write a note, then go find the file. If you can locate a plain .md you could email yourself, the app respects your ownership. If you can't, treat "markdown support" as cosmetic and weigh the lock-in accordingly. From there, let your actual habit decide — capture-first, write-first, or link-first — using best notes apps by use case or the deeper app comparison criteria to break the tie. Whatever you choose, favour tools that build evergreen notes you'll still be able to read in ten years.
