Debugging a broken email template used to mean copying headers, body text, and HTML separately and pasting them into an AI with a long explanation of what you were looking at. LocalMail.dev removes all of that friction.
Click the Copy for AI button in any email's toolbar. LocalMail.dev instantly builds a structured markdown document containing the full email context: subject, from, to, date, size, all headers as a code block, the plain text body, and the complete HTML source. One click, one paste.
The output is formatted so that AI assistants can parse it accurately. Headers appear as a labelled code block. Body content is clearly separated. You can paste it directly into ChatGPT, Claude, Perplexity, or any other assistant and ask your question without any additional setup.
