How it works

Your AI does the thinking. unPaper supplies the capability.

unPaper is not an AI service — it upgrades the one you already use. It hands your assistant a deck format it is flawless at (HTML), then turns the result into a flawless 16:9 PDF or an editable PowerPoint when you need one. Everything happens in your browser, on any device.

1. Create the HTML deck prompt

Choose a deck style, add a short brief, and copy the generated prompt. The prompt includes the complete self-contained HTML template and strict rules for fitting the slide format.

2. Use your chosen AI separately

Paste the prompt into ChatGPT, Claude, Copilot, Gemini, or the assistant approved in your environment. unPaper does not see that chat and does not generate the content itself.

3. Download a PDF or PowerPoint

Paste the deck back into unPaper and download a flawless 16:9 PDF, on any device including your phone, or an editable .pptx where every text box stays retypeable. The self-contained HTML stays yours either way. All in the browser.

Verifiable privacy
