Show HN: Slidum – A player for the HTML presentations AI writes
Slidum is an online player that turns AI-generated HTML presentations into shareable links, eliminating downloads and sign-ups, with full-screen playback and access control.
The player for AI-made decks
Your AI made the deck. Send a link, not a file.
Paste the HTML Claude or ChatGPT wrote. It plays as a real presentation and turns into a link anyone opens in the browser — no download, no account. You decide who gets in.

The problem
Your best work, stuck as a file.
A deck the AI made in seconds, and nowhere good to send it.

The Downloads graveyard
deck-final-v3.html, deck-final-FINAL.html, deck-real-final.html. Beautiful decks, buried in a folder nobody reopens.

The “just download it, trust me” text
You send a file and a paragraph of instructions. Half your audience never opens it.
The WhatsApp paste that renders as code
Dropped into a chat, your deck shows up as raw HTML. The magic never loads.
Lights down
It just plays.
Open the link and the lights go down — the real player takes over: arrow keys, slide thumbnails, full screen, and the counter in the corner.

Everything after the file
From a dead file to a living link.
Organize
A library, not a Downloads folder.
Every deck your AI hands back lands in one place, named and ready to play — yours and the ones people share with you.
