Mai Chat Exporter for ChatGPT

Save an open ChatGPT chat as Markdown, TXT, or JSON on your device. PDF uses the print dialog. Not an OpenAI product.

Mai Chat Exporter for ChatGPT saves ChatGPT messages that are already loaded and read on the open page, or converts a JSON file you choose on your device. It is not an OpenAI product and not a full-account or full-thread backup. The public developer name is Halun. Privacy and support: eratolabcool@gmail.com. Privacy policy: https://maiverse.cc/privacy/mai-chat-exporter On chatgpt.com and chat.openai.com you can export the messages already read, assistant replies only, messages you select, or one assistant answer. Markdown, TXT, and JSON download in the browser. JSON uses the schema mai-chat-export/v1. PDF opens this extension’s print view and the browser print dialog. Choose Save as PDF. This version does not create a PDF file by itself. A logged-in Chrome check saved one PDF that way; the file included the loaded messages and a completeness warning. Markdown from that check kept the tested headings, Chinese text, lists, code, and tables, and still had extra blank lines and code fences without a language tag. You can copy the messages already read as Markdown. Optional scrolling can try to load more of the same open conversation before a full-page export. It is cancelable, stays inside that conversation, and stops on a time, step, or size limit. If the page has no usable numeric message indexes, the extension does not auto-download. That happened in the logged-in check (missing-orders). Do not describe this as a reliable full transcript. The archive page can import an unzipped official conversations.json, a split JSON file, or JSON this extension exported. It does not open a ZIP archive. Message text is handled in the browser. The extension has no account and no analytics endpoint, and the reviewed code does not upload the conversation to a developer server. The chosen format is stored locally. A preview or print handoff stays in extension session storage until the preview page reads it, the tab closes, or it expires. That local handling is still use of the conversation. Other branches, messages the page has not loaded, images, attachments, canvas, and interactive charts can be missing. Math stays as LaTeX source. Word and DOCX are not supported. Import preview rejects JSON files over 20 MB. A conversation-turn-N value is only an order number. When that number is the only signal, the extension does not guess the speaker. The logged-in check covered one visible user-then-assistant pair and the formats named above. It did not pass a full-thread or full-account export.
