Obsidian works with AI. Your AI chats aren't in it.
The vault is only as useful as the notes you actually put in it. Most AI chats never make it there.
The short version
One conversation becomes one dated Markdown file inside the vault. Chatlog saves new ChatGPT and Claude activity while Chrome is open, site access is enabled and automatic saving is on. Grok is available for manual saves from its open chat.
The gap
People use Obsidian as the place where projects live. The brief, the outline, the decision, the links. Then they do the thinking in ChatGPT or Claude, and that thinking stays in a sidebar. The vault has the conclusion. The conversation that produced it is somewhere else, under a title you will not remember.
That split is easy to ignore until you need the earlier version. The chat was renamed. The account is a work login you no longer have. The thread was deleted. The paragraph you wanted was three scrolls up and you did not copy it.
Obsidian cannot search a chat it never received. Graph view cannot link a note to a conversation that is still trapped on a website. A backup of the vault does not include the thread you had this morning.
A second brain only works if the raw material sits with the notes you already trust. An AI chat is raw material. Filed as a note, it can be quoted, linked, and found the same way as a meeting note you wrote yourself.
What changes when chats are plain files
A Markdown file is boring in the best way. Search finds a sentence. A link from your project note points at the chat that settled the question. The graph shows that connection the same way it shows any other note. A copy of the folder is a copy of the work.
You can open the file in Obsidian, in VS Code, or in anything that reads text. You are not waiting on an export format. You are not logged in. The file still opens.
One conversation should be one file. A single giant export is hard to link to and hard to tell apart from the export you made last month. A file named with the date and the title is something you can find again.
A simple folder layout
Keep the chats inside the vault, in their own folder, split by the site they came from. A ChatGPT thread lands in chatgpt/. A Claude thread lands in claude/. Claude project chats go one level deeper, under claude/projects/. Supported downloadable files sit under each provider’s files/ folder. Available Claude artifact source sits in claude/artifacts/ when enabled.

The note itself starts with a small header: title, dates, source, and a content hash. The body is the conversation, labeled You, ChatGPT, or Claude. You can add your own links under that. If a later save would overwrite an edit you made, your file is kept and the new text arrives as a separate copy.
Keeping it current without effort
After you choose a vault folder, connect ChatGPT or Claude, allow access to that site and refresh its tab, automatic saving captures new and continued chats while Chrome is open. Chatlog does not scan account history. You can save one open ChatGPT or Claude chat from the popup; Grok is manual only. For older ChatGPT or Claude chats, import the provider's official export ZIP or JSON in settings. Gemini is not supported.
Images need accessible download data or a matching file in an imported export. ChatGPT memory and dedicated Canvas recovery are not supported. Claude artifact source is saved when available and enabled; full interactive previews are not preserved, and anything unreadable is marked in the note.
The chats stay on your machine. There is no Chatlog account to create, and the conversation is not uploaded to us. Notion can be a second copy if you want one. The folder does not depend on it.
