User Shows Claude Desktop Organizing an Obsidian Vault
Reddit user HowzoTV demonstrated connecting the Claude desktop app to an Obsidian vault folder without plugins or an MCP server. In a reported test using a 24-note vault, Claude created six client folders, renamed vague notes, added related-note links and an index, and compared the edited notes with a backup. A second prompt reportedly found nine open tasks and placed them in a daily note with links to their source notes, while a third produced an answer with a link to the relevant note. The user says a paid Claude plan, Pro or higher, is required, recommends backing up files first and using a copy for sensitive material, and notes that vault contents are sent to Anthropic like other chat data. These results come from one Reddit post and were not independently verified.
The post provides a concrete, three-prompt workflow for using Claude Desktop's local-folder access to organize, link and query Markdown notes. It also highlights practical backup and privacy cautions, although the demonstrated results are anecdotal rather than independently verified.
I wanted to see if Claude could clean up a really messy vault without any plugin or MCP server. So I made a test vault with 24 notes like a freelancer would have: Untitled, Untitled 2, notes 2, random... no folders, no links. Graph view was 24 loose dots.
Why this works at all: a vault is just a folder of .md files, and the Claude desktop app can open a folder on your computer and read/edit the files in it.
Setup (about 2 min)
- Claude desktop app → new session → choose "This computer"
- Click Choose → Open folder → pick your vault
- It asks if you trust the folder (it can read, write and run files there), so back up first
Prompt 1: sort + link
Back up my notes to a folder on the Desktop called Notes Backup, then sort them into folders, link related notes, and make an Index note.
