ChatGPT export to Markdown
Turn conversations.json from ChatGPT’s data export into one clean Markdown file per conversation: speaker headings, code blocks intact, only the branch you actually saw.

- One .md per conversation
Markdown to X (Twitter) article
Paste Markdown, copy the body once, and drop it into the X Articles editor. Guided markers handle the code, tables, and images the editor cannot paste.

Why these exist
Sensefold keeps the articles, threads, videos, notes, and AI conversations you capture as Markdown, so the AI you already use can read them over MCP. Markdown in, Markdown out is the whole idea, and these tools cover the two edges that come up most: getting an archive of chats into Markdown, and getting Markdown into a platform that does not accept it. If you want the chats captured as you have them, the Chrome extension does that in one click.
