Click the body — try writing a line

A bookshop, and a way of living

A good bookshop
does more than sell books.

01 Starting with a pause

Let every visit bring something new.
Your words, your pace.Edits in this demo only affect this page
01

Just write — the thought follows.

Edit inside the formatted body. Headings, lists, images, and tables all live where you need them.

Change the mood
Bring that focus back to the desktop

Good expression
is more than finishing a draft.

Sometimes you dive into the writing,
sometimes you step back to see.
Markdeck gives each state the space it needs.

01

Write

Let the words flow

Edit inside the formatted document. Layout happens as you write. Keep attention on the content.

Begin with a single sentence
02

Outline

Trace the shape of your thinking

Spread sections across a canvas. Drag, connect, and drop in a sticky note. Notice what is still missing.

See the whole from the parts
03

Present

Share the thought with ease

Walk through the content in the order you want to tell it. Keep a clear through-line for every conversation.

From thinking to shared understanding

A quiet interface,
attentive details.

The tool should not interrupt your thinking.
Common actions sit exactly where your hand expects them.

ON A QUIET AFTERNOON03

A new angle
on an ordinary day.

Words and pictures can each find a comfortable place.

A place for words & everything around them.
01

Text and images, in easy company

Soft image edges, adjustable sizes, and two- or three-column groups let visuals settle naturally into the prose.

02

Long documents stay navigable

The table of contents follows your heading hierarchy. Search sections, or open a reference doc, and read and write in one place.

03

Every edit, with room to breathe

The body autosaves. Revision history is viewable. Tables, images, and text actions all support undo.

04

Your light, your rhythm

Nine built-in themes for different writing moods. Adjust body size and shape the workspace until it feels right.

Your files,
always in your hands.

Save your work in familiar Markdown.
Writing stays local. Take it with you when you want to share.

A few things
you might want to know.

See the user guide
Is Markdeck an online editor?

Markdeck is a Mac desktop app. The interactive demo on this site shows how writing, outlining, and presentation feel; edits in the demo only apply to this page. Real documents open and save inside the desktop app.

Do I need an account to write?

No. The desktop app opens local Markdown files directly. Writing, outlining, and presenting all work offline. Images hosted online still need a connection.

Will outlining or presenting change my original document?

No. Sticky notes, card positions, connections, and presentation order are stored separately. You can reorganize your thinking or present only a few sections while the Markdown body stays in its original order.

How do I share documents together with their images?

Export a standalone HTML or PDF, or bundle the Markdown and local images together as a ZIP. If you share a .md file directly, include the folder it references for images.

Which systems are supported today?

The current desktop build targets Apple Silicon Macs. Builds for Windows, Linux, and Intel Macs are not yet available.

Can I keep using my existing Markdown files?

Yes. Open UTF-8 encoded .md, .markdown, or .txt files directly, up to 10 MB each. Images should live inside the document folder; if something is missing, you can reselect it.
