By connecting the plugin to an AI provider like OpenCode, users can query their notes conversationally, as shown when Rijul asked when he did Teams integration work and received relevant documents. The approach aims to speed up workflows by letting an AI agent act as a librarian for personal notes.", "body_md": "*Hello, I'm Rijul. I'm building git-lrc, a micro AI code reviewer that runs on every commit. It's free and source-available on GitHub. Star git-lrc to help more developers discover the project. Do give it a try and share your feedback*\n\nAre you someone who uses Obsidian day-to-day?\n\nSuppose someone asks you about some work you did a few months ago. Or maybe you want to refer back to how you solved a particular problem.\n\nBut obviously, you won't remember all the details.\n\nYou may need to go through your Obsidian notes just to figure out what you did.\n\nThat sounds pretty cumbersome.\n\nWhen I already had agents doing lower-level work for me, I started thinking, why not get an agent to handle this task as well?\n\nSo here I'll show you how I did it.\n\nThis is a plugin I recently stumbled across.\n\nJust go to **Settings → Community Plugins** and search for **Copilot**.\n\nYou should find the Copilot plugin.\n\nJust install it.\n\nOnce installed, you can connect it to an AI provider. In my case, I connected it to OpenCode.\n\nIn the Obsidian sidebar, you'll see a button for Copilot.\n\nClick it, and you now have an AI agent that can work with your Obsidian vault.\n\nSo let me demonstrate the problem I had.\n\nI did a **Teams integration** for an app recently, but I needed to know the specifics of how and when I did it.\n\nInstead of manually searching through my notes and wasting time, I simply asked Copilot:\n\n```\nWhen did I do stuff related to Teams integration?\n```\n\nYou can see the output here:\n\nNow I can see the relevant documents, and I can continue asking questions about them.\n\nFor example, I can dig deeper into what I did, when I did it, or how I implemented something.\n\nSo this is another way you can make your existing workflow a little faster.\n\nIt's basically another agent working with your notes, acting more like a second brain that can dig through your old information and bring it back when you need it.\n\nKind of like a librarian for your brain.\n\nSee you in the next article.\n\nAI agents write code fast. They also silently remove logic, change behavior, and introduce bugs -- without telling you. You often find out in production.\n\n[git-lrc](https://github.com/HexmosTech/git-lrc) fixes this. It hooks into git commit and reviews every diff before it lands. 60-second setup. Completely free.\n\nAny feedback or contributors are welcome! It's online, source-available, and ready for anyone to use.\n\nGive it a ⭐ [star on Github](https://github.com/HexmosTech/git-lrc)", "url": "https://wpnews.pro/news/turn-your-obsidian-vault-into-an-ai-powered-second-brain", "canonical_source": "https://dev.to/rijultp/turn-your-obsidian-vault-into-an-ai-powered-second-brain-559", "published_at": "2026-08-27 20:26:30+00:00", "updated_at": "2026-08-27 20:49:15.816304+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools"], "entities": ["Obsidian", "Copilot", "OpenCode", "Rijul", "git-lrc", "GitHub"], "alternates": {"html": "https://wpnews.pro/news/turn-your-obsidian-vault-into-an-ai-powered-second-brain", "markdown": "https://wpnews.pro/news/turn-your-obsidian-vault-into-an-ai-powered-second-brain.md", "text": "https://wpnews.pro/news/turn-your-obsidian-vault-into-an-ai-powered-second-brain.txt", "jsonld": "https://wpnews.pro/news/turn-your-obsidian-vault-into-an-ai-powered-second-brain.jsonld"}}
