Markdown, PDF, Word or JSON: which format should you use for your AI chats?

Each export format is good at something different. Here is a simple guide to choosing between Markdown, PDF, Word, HTML, JSON, plain text and pictures for your ChatGPT, Claude and Gemini chats.

When you export a conversation from ChatGPT, Claude, Gemini or another AI, the format you pick decides what you can do with it later. A PDF is perfect for sharing, but awkward to edit. Markdown is perfect for notes, but confusing to someone who has never seen it. Here is how to choose.

The quick answer

Format	Best for	Opens with
Markdown (.md)	Notes apps and long-term archives	Obsidian, Logseq, Notion, Bear, any text editor
PDF (.pdf)	Sharing, printing, sending to clients	Any device
Word (.docx)	Editing and turning a chat into a report	Microsoft Word, Google Docs, LibreOffice
HTML (.html)	A faithful copy you can open in a browser	Any web browser
JSON (.json)	Developers and data processing	Code, scripts, data tools
Plain text (.txt)	The simplest copy possible	Anything
Picture (.png)	Sharing a short exchange on social media	Any image viewer

Markdown: for your notes and your archive

Markdown is plain text with simple symbols for formatting, like # for headings and ** for bold. It is small, works offline, never goes out of date, and every notes app understands it.

AI Chat Exporter’s Markdown keeps code blocks, tables and maths (as LaTeX, with $...$ and $$...$$), and adds the chat’s title, date, link and tags at the top of the file. Apps like Obsidian read that information, so your chats become searchable notes you can link and tag.

Choose Markdown if you keep notes in Obsidian, Logseq, Notion, Bear or NotePlan, or you want an archive that will still open in 20 years.

PDF: for sharing and printing

A PDF looks the same on every phone, computer and printer. Our PDF export includes page numbers and keeps code and equations readable, so it is ready to attach to an email or hand to a colleague.

Choose PDF if someone else will read the chat, or you need a fixed record of what was said.

Word: for turning a chat into a document

AI conversations often become the first draft of something bigger: a report, a proposal, a lesson plan. AI Chat Exporter creates a real Word file (.docx), not a web page renamed to look like one, so it opens cleanly in Microsoft Word and Google Docs and you can edit it straight away.

Choose Word if you want to edit, restructure or add to the conversation.

HTML: a faithful copy in your browser

HTML keeps the look of the conversation, with formatting, code highlighting and images, in a single file that opens in any browser. It is a good “just in case” copy when you are not sure what you will need later.

JSON: for developers

JSON stores every message with its role and order in a structured way that programs can read. Use it if you want to analyse your chats, feed them into your own tools, or move them into another app.

AI Chat Exporter Premium also exports special developer formats: OpenAI fine-tuning (JSONL), the ChatGPT official export format, SillyTavern / TavernAI and Oobabooga.

Plain text and pictures

Plain text drops all formatting. It is useful when you want to paste a conversation somewhere that does not understand formatting.

Pictures turn a short exchange into a neat image, great for showing a funny or impressive answer on social media. There is a high-quality option for sharp text.

Our recommendation

For your own archive: Markdown.
For other people: PDF.
For further work: Word.

And you do not have to choose just once. With AI Chat Exporter you can export the same chat in as many formats as you like, for free.
