Beautiful slides & docs from your own AI.

Even if your AI can’t make nice slides yet. unPaper hands it a print-ready HTML format – the one format every AI writes flawlessly – and turns the result into a real, editable PowerPoint when you need one.

Already have the HTML? Convert it

Native to AI. Every AI writes HTML flawlessly – including the assistant you already use at work.
Prints & converts. Pixel-perfect 16:9 slides and A4 pages as PDF – or one click to an editable .pptx.
Yours forever. One private file, no login. Re-edit it with any AI, anytime.

Ask your AI for PowerPoint…

deck.pptx

Unpredictable: overflows, won't print

…or for HTML, with unPaper’s prompt

deck.html

Fits, prints – and converts to .pptx

Privacy by design

Nothing you type, paste or convert leaves your browser. No accounts, no uploads, no servers reading your content – unPaper is static files, and all the work happens on your device. The only place your content ever goes is the AI chat you choose to paste the prompt into.

Don’t take our word for it: load the converter, switch off your internet, convert. It still works.

Or read the code yourself – it’s public: github.com/mitsue-eth/unpaper

One loop, two steps

HTML first · other formats second

01 · Make

Slides & docs, written by your AI

Pick a format – 16:9 deck or A4 document – and unPaper builds the whole prompt: your brief, the rules and a print-ready example file. Paste it into any AI; get back a finished HTML file that prints perfectly.

02 · Convert

HTML → editable PowerPoint

Drop the HTML deck on the converter and get a real .pptx: every text line editable, every card and line a movable shape. Runs entirely in your browser – even offline.

Open the converter

The HTML file stays the source of truth – private, self-contained, re-editable by any AI. PowerPoint is an export; Word and Google formats may follow. How it works
