A .deck is a folder, zipped. It needs deck.json to name itself, and index.html to show itself. Everything else — images, fonts, scripts — is up to you.
// deck.json — the manifest { "name": "My Talk", "author": "Ada", "description": "A talk about Transformers", "cover": "cover.png", "version": "1.0.0" }
No arrow keys hijacked. No space bar stolen. Deck stays out of your way — you decide what each key does. Only a handful stay with the window itself.
No browser tab. No loading spinner. It opens in its own window, full-screen ready, just like Keynote.
Describe your talk, upload your notes, paste an outline. Your AI turns it into real slides you can actually give.
Animations, videos, live charts, 3D models, tiny games — if the web can do it, your deck can do it.
No account. No upload. No one watching. Your deck sits on your disk — like a document should.
Nothing to learn. Nothing to set up. Tell your AI what you want — and you're done.
"Turn these Q3 numbers into a board deck." Or drop in your notes, your script, your outline — whatever you've got.
Minutes later, a real .deck file lands on your computer. Not a link. Not a web page. A file.
Full-screen window. Arrow keys to move. Esc to exit. The same file works on your laptop, your phone, or a friend's Mac.
A small set of instructions that teaches any AI tool the Deck format — pagination, sandbox rules, what to avoid. Just say deck and your AI picks it up automatically.
No uploads. No servers. No analytics. Your deck never leaves your machine unless you send it yourself.
Each deck runs in an isolated window. It can't read your files or peek at other apps — even if someone sends you a shady one.
By default, a deck can't phone home. Period. If it ever needs to, you'll know, and you'll be the one to decide.
A .deck is not a black box — it's the web, zipped. You can always look inside and see exactly what it does.

Double-click any .deck. It opens full-screen, in its own window, ready to go.
