How it works
1.
-Type your slides
-Markdown-ish text in the box: headings, bullets, paragraphs, --- between slides. The syntax is the stuff you already type.
2.
-Watch it set live
-Every keystroke re-typesets the deck on the right. Navigate with arrow keys or swipe; the progress bar keeps your place.
-3.
-Take the file with you
-One button copies the deck as a single self-contained HTML file. Open it anywhere, present it offline, email it, done.
-The copied file is a self-contained deck: open it in any browser and use ← / → to present.

-Proof that people want prose in, polished output out — no canvas-dragging required.
-Structured text becoming layout: the same bet MDecks makes for slides.
-Even geometry is going plain-text. Your weekly status deck can too.

-Honest limits
-
-
- Nothing is saved — close the tab and your text is gone. Copy the HTML or paste your source somewhere safe. -
- One layout, one typeface, no themes. The deck looks like this page, not like your brand. -
- No images, tables, or nested lists yet — headings, bullets, paragraphs, and inline emphasis only. -
- No speaker notes, no presenter view, no PDF export. That is the Pro idea, if enough people ask for it. -
- The copy button needs a modern browser with clipboard access; on very old browsers it may silently fail. -
