Running Claude Code from inside Obsidian is now a one-plugin install. Obsidian AI Copilot, a free open-source plugin built by developer Spencer Marx, routes AI agent CLI tools through Obsidian's interface so you can run them against your vault content without leaving the app.
The plugin detects which AI CLI tools you have installed - Claude Code, OpenCode, or others - and surfaces them inside Obsidian. You pick the tool, give it a prompt, and it operates on whatever content is in your workspace.
For writers, researchers, and anyone who uses Obsidian as a central hub for their work, this removes a persistent context switch. Running Claude Code against your notes previously meant copy-pasting between apps or working from a separate terminal window.
This is an individual developer project, not a company-backed product. Marx is transparent in the documentation that it has been working well for his own workflow - which sets appropriate expectations. Early users should expect the update cadence of a one-person side project.
The plugin is available at github.com/spencermarx/obsidian-ai.
