Marklet: Markdown Editor
Live preview for Markdown
Only for Mac
Free
Mac
Now universal for Intel and Apple silicon. Autosave, linked notes, and formatting that appears as you type. No preview pane, no split screen, no second copy.
Marklet is a fast, native Markdown editor for macOS, built in Swift. Since Marklet is built on TextEdit, it is light, familiar, and instantaneously opens. It
formats your text as you write: bold, italics, headings, lists, and links style
themselves inline, and the raw markers show only when your cursor is on them. No
split screen, no separate preview pane. Just clean rendered Markdown you can still edit.
Tables, code blocks, and LaTeX math render inline as you type, so you never
leave your document to see the result. And it all stays editable: tweak rendered
tables directly, resize images right in place, and shape your document to your
heart's content.
• Native Swift app, not Electron: light, fast, and easy on memory
• Feels like TextEdit, with live Markdown formatting built in
• Formats as you type: bold, italics, headings, lists, links
• Raw markers appear only where your cursor sits
• Tables, code blocks, and LaTeX math, rendered inline
• Edit rendered tables directly and resize images in place
• Work across documents in tabs (Cmd+T)
• Command palette for everything, Obsidian style (Cmd+Shift+P)
• Print your notes cleanly (Cmd+P)
• Make it yours: adjustable appearance, fonts, and more in Settings
• Files stay plain .md, open and edit them in any app
• Fully local: no account, no subscription, no cloud, no tracking
Your writing stays yours: plain .md files on your Mac, with nothing to sign
into and nothing phoning home.

Marklet 1.1
Saving on your terms
Marklet saves when you ask it to, and warns you before closing anything unsaved. Prefer the way most Mac apps work? Turn on Auto Save with Versions in Settings and Marklet writes as you type, keeping earlier drafts available from File then Revert To.
Files changed outside Marklet
Edit the same note in another app and Marklet notices. When both copies changed it shows you exactly what differs and lets you keep yours, take theirs, or combine them. Changes that do not overlap merge on their own.
Linked notes
Write two square brackets around a note name to link it. Links show whether the note exists, and clicking one opens it in a tab. Click a link to a note you have not written yet and Marklet starts it for you, named and ready.
Faster with long documents
Very long files now highlight progressively, so typing stays responsive while the rest of the document catches up.
Picking up where you left off
Marklet can reopen the documents you had open when you last quit, even when macOS is set to close windows for every other app.
Intel Macs
Marklet now runs natively on both Intel and Apple silicon.
Also in this release
New tabs open in properly. Reading Mode bug fix. Ordered task lists keep their alignment. Settings explains what the substitution options actually do, and you can choose whether Marklet opens a blank document at launch or restores your last session.
