Converts highlighted html elements from most web pages into clean Markdown, expressly integrating conversion and export support for ChatGPT Deep Research reports and similar elements across various web pages, including citation extraction with source URLs from sandboxed iframes and srcdoc-embedded report handling, featuring 6 citation styles, YAML frontmatter support, a visual element picker, live preview editor, and clipboard/file/GitHub/Obsidian export capability.
ChatGPT's Deep Research reports (as of ~March, 2026) are rendered inside sandboxed <iframe> elements on web-sandbox.oaiusercontent.com. Standard web clippers and HTML-to-Markdown tools cannot access these iframes, causing userscript malfunctions and empty or malformed outputs. Saved/exported ChatGPT pages embed the report as HTML-entity-encoded srcdoc attributes with multiple layers of encoding. Citation URLs are stored in React's internal fiber state, invisible in the static HTML. This script rectifys all three challenges, building upon the exceptional work of shiquda and ChinaGodMan's MarkDown Cloud Cut Notes.
This tool is a direct fork of shiquda and ChinaGodMan's MarkDown Cloud Cut Notes (v2025.03.19), with additional inspiration drawn from Chris Kephart's exemplary ChatGPT Deep Research Markdown Exporter. The source code has been substantially refactored, introducing the following revisions:
