ChatGPT-, Claude- und Gemini-Verlaeufe als Markdown nach Obsidian sichern

Posted on Oct 14 • Originally published at hexloomlabs.com

Disclosure: this article was written with AI assistance (Claude, by Anthropic) for Hexloom Labs, which makes the extension mentioned at the end.

If you keep notes in Obsidian, you have probably wanted your ChatGPT, Claude and Gemini conversations in the same vault as everything else, as plain Markdown files you can search and link. Here are the routes that exist today, and where each one stops.

Each service has some form of account export.

The limits: you wait for an email, the result is one large file rather than one note per chat, and you still have to turn JSON into Markdown yourself.

Select the conversation, copy, paste into a new note. It works for one chat. Code blocks often lose their fences, roles ("You said", "ChatGPT said") end up as plain text, and you add a title and date by hand every time.

If you are comfortable with a few lines of Python, you can read the ChatGPT conversations.json and write one file per conversation. The format is a tree of message nodes rather than a flat list, so you need to walk it from the current node back to the root to get the messages in order. It is a good afternoon project, and it only covers the one service whose export you scripted.

An extension can read the conversation already rendered in your tab and save it as a file. The things worth checking before you install one:

We make one of these: Hexloom Chat Archive. It saves the open chat on chatgpt.com, claude.ai or gemini.google.com as Markdown or JSON with Obsidian-friendly frontmatter, locally in the browser, with no analytics and no server of ours involved.

The free version exports the chat you have open. Pro ($4 a month or $29 a year) adds bulk archiving of your history for ChatGPT and Gemini, saving into a folder you pick, and local search.

Honest limits, from the product page: it has been tested against recorded copies of the pages rather than logged-in sessions, so it may report "No messages found" on a given site until a fix ships. Images are linked, not embedded, and attachments are not supported. Bulk archiving opens your chats automatically in your own session, which some services' terms restrict, so it is off on claude.ai and is used at your own risk elsewhere. It needs Chrome or Edge 137 or later, and it is available on Microsoft Edge now, with the Chrome Web Store version in review.
