Library · v0.3.5
Extract rendered pages into structured Markdown.
Mantis is a small extraction library that turns rendered web content into clean Markdown for agents.
It runs over the live DOM, so it works after client-side rendering and logged-in state. Nothing is uploaded by default.

Why not normal copy?
Browser copy brings navigation, sidebars, footer text, and no source metadata. Mantis keeps the article-shaped content and emits metadata an agent can use.

Paste converter
For saved HTML or a strict site where you copied the rendered HTML yourself, paste a JSON blob or raw HTML below. This page loads Mantis from the GitHub repo through jsDelivr.
Copy rendered HTML
Run this in the page console when you need the paste fallback:
copy(JSON.stringify({url: location.href, html: document.documentElement.outerHTML}))
