Most presentation tools are built for a stage.
Big screen. Captive audience. Clicker in hand.
But what about content people consume on their own — on a phone, at their own pace, whenever it fits into their day?
Slideshows weren't designed for that. Vibedeck was.
Remember index cards?
One idea per card. Focused. Constrained. Sequenced to build understanding without overwhelming.
Students have been using them for centuries because they work — not despite the constraint, but because of it.
Vibedeck brings that model to the web.
A platform for creating and browsing card decks authored in plain markdown.
You write a markdown file. Vibedeck turns it into a beautiful, paginated card experience that works on any device — phone, tablet, desktop, or projected screen.
No special software. No complex tooling. Just markdown and a clear idea.
Vibedeck is not a presentation tool.
It is a reading and learning experience that happens to work beautifully in a presentation context.
The distinction matters. The design decisions — mobile-first, paginated, card-constrained — all follow from that.
Vibedeck supports five card types in v1:
Title — the opening card, large display treatment
Concept — one idea, explained cleanly. The constraint is the feature.
Summary — big picture consolidation, bullet points, palette cleanser between concept runs
Graphic — full image or chart with a caption
Quote — a pull quote, styled distinctively
Every deck is a single markdown file with YAML frontmatter.
Cards are separated by ---. Each card declares its type in its own frontmatter block.
That's the entire format. If you can write markdown, you can author a Vibedeck deck.
A deck frontmatter block at the top defines the title, author, topic, keywords, and theme.
Each card follows — separated by --- — with its own type declaration and content.
Title card. Concept cards. Summary cards. Quote cards. Graphic cards. That's the whole vocabulary.
Decks are grouped by topic — a slug that becomes part of the URL.
vibedeck.online/z13 — all astrology decks
vibedeck.online/tok — all Theory of Knowledge decks
Each deck also carries keywords for finer-grained thematic grouping within a topic.
Vibedeck is open source under the MIT license.
The codebase is yours to clone, deploy, and build on. Run your own instance for your own content — your deck content stays on your domain, building your authority, not ours.
vibedeck.online is the proof of concept. Your instance is the point.
Architectural decisions and editorial judgment by a human. Execution assisted by a very carefully guided code djinni.
