Who it is for

People who make a quick throwaway deck every week — sprint demos, status updates, lunch talks — and would rather type than drag boxes in Google Slides or Keynote. If you already write everything else in Markdown, .mdeck lets you write your deck the same way.

How to use it

Open the page and type markdown-ish text in the editor on the left. It comes preloaded with a sample deck so you can see real output immediately.
Watch the preview on the right re-typeset live. Navigate with the arrow keys (or swipe on touch screens); a progress bar tracks your place.
Press Copy deck as HTML to copy the whole deck as one self-contained HTML file. Open it in any browser and present with the arrow keys — offline, no dependencies.

The syntax:

# Title and ## Subtitle for headings
- bullet (or * bullet) for lists
--- on its own line starts a new slide
Inline **bold**, *italic*, and `code`
[text](https://…) for a link
Any other line becomes a paragraph

Everything runs in the page. Nothing is saved, nothing is sent anywhere, no account is needed, and the page is free.

Honest limits

Nothing is saved — close the tab and your text is gone.
One layout and one typeface; no themes or branding.
No images, tables, or nested lists yet.
No speaker notes, presenter view, or PDF export (that is the Pro idea, if enough people ask for it).
The copy button needs a modern browser with clipboard access.

.mdeck Pro (not built yet)

The paid idea: saved decks, themes, speaker notes, PDF export, and shareable links — still plain text in. Early access is collected via a public GitHub issue form; no email, no payment, nothing is charged today. A 👍 on the signal issue counts as interest too.
