Only for Mac
$2.99
Mac
Discover Nord, Catppuccin, and Dracula in the community theme browser. Make Markdown your own with live formatting, editable tables, math, and code.
Marklet is a Markdown editor that formats your writing as you type.
Headings grow, bold turns bold, and links become links. Choose live formatting that reveals Markdown as you edit, True WYSIWYG, direct source editing, or Reading mode. Your document remains a plain Markdown file in every mode.
Write, and it looks right.
Tables, images, math, and code
Tables render as tables and can be edited in place, with Tab to move between cells. Images appear inline and can be resized by dragging. Mathematical expressions written in LaTeX are typeset properly, inline or as display equations. Code blocks are syntax highlighted, with a button to copy the block.
Linked notes
Link one note to another by wrapping its name in double square brackets. Marklet shows at a glance whether the note exists, opens it in a tab when you click, and offers to create it when it does not exist yet. Headings and display names work too, so a link can point at a section or read however you like in the sentence.
Your files stay yours
Marklet edits plain Markdown files in place, wherever you keep them. There is no library to import into, no proprietary format, and no account. Open the notes you already have and start editing. Everything you write remains a plain text file you can open in anything, forever.
Saving that suits you
Leave autosave on and your work is written as you type, with earlier versions available through Revert To. Turn it off and Marklet saves only when you ask. If another program changes a file while you have it open, Marklet tells you what changed and lets you decide, rather than quietly picking a side.
Make it yours
Browse community themes with native previews, save custom colors, and optionally use a theme's typography. The formatting toolbar follows your theme and keeps common editing commands close by. Revisit setup anytime from Help or Settings.
Built for writing
Tabs, a command palette, keyboard shortcuts for every formatting command, a document outline, focus and Reading modes, light and dark appearances, and control over fonts, spacing, and colors.
Built for the Mac in Swift, with native text rendering.
Requires macOS 14 or later. Runs natively on Apple silicon and Intel Macs.

Make Marklet yours with community themes including Nord, Catppuccin, and Dracula. Find them in the theme browser, preview their colors, and choose your favorite.
Marklet 1.8 also brings a formatting toolbar, flexible editing modes, and smoother table editing. This update includes the improvements released since App Store version 1.2.
Themes and colors
Browse community themes with previews, screenshots, search, and popularity sorting. Install themes to keep them available, then choose which one to use. Your custom color changes survive switching themes and updating them.
Save your current colors as a named custom theme. Marklet Warm offers a warm palette, and the native color picker supports a color square, wheel, opacity, HEXA, and RGBA values. Optional theme typography reports unavailable fonts and their fallbacks.
Theme colors now reach document headers, tables, native previews, and the command palette. Tables can also use neutral colors.
Edit your way
Choose Live Formatting, True WYSIWYG, Source, or Reading, with up to three configurable mode buttons and shortcuts. Leave unused positions set to None. With two modes enabled, Command E and Command Shift E both switch between them.
The themed formatting toolbar can float at the top or bottom, or appear near selected text. Format emphasis, headings, lists, links, tables, code, math, images, and callouts. Configure toolbar visibility separately for each enabled mode.
True WYSIWYG keeps typed punctuation literal and carries active formatting forward as you type. Copy preserves formatting at selection boundaries. Paste, Paste and Match Style, and Paste as Literal Text provide different ways to bring text into your notes.
Smoother tables and editing
Insert Table offers a grid size picker. Table columns grow into available space, then wrap without shrinking your font. Individual cells have a width limit, rows grow as you type, and large tables are more responsive.
Cell editing preserves padding and alignment. Shift and the arrow keys select text for copying. Typing with cells selected starts in the table, and dragging near either horizontal edge scrolls to extend your selection. Revealing source clears the rendered grid cleanly.
Link and image editors have separate text and destination fields. Math editing keeps the surrounding delimiters out of the field. Lists keep their indentation and undo steps, bullets align with checkboxes, and leaving inline code no longer carries the wrong style forward. Nested formatting markers and command palette actions behave more consistently.
Setup
Onboarding has native previews of your enabled modes and can be reopened anytime from Help or Settings. Review Setup starts with your current choices. The themed What's New window can also be reopened from Help.
Finder previews
Quick Look follows your theme and offers a choice between formatted previews and styled Markdown with its markers visible. Finder previews remain read only.
Requires macOS 14 or later. Runs natively on Apple silicon and Intel Macs. (Also sorry for the delay, updating through the app store is painful.)
