Copilot for Obsidian is your ultimate in‐vault AI assistant with chat-based vault search, web and youtube support, powerful context processing and ever-expanding agentic capabilities—all within Obsidian's highly customizable workspace.
- 🔒 Your data is 100% yours: Local search and storage, and full control of your data if you use self-hosted models.
- 🧠 Bring Your Own Model: Tap any OpenAI-compatible or local model to uncover insights, spark connections, and create content.
- 🖼️ Multimedia understanding: Drop in webpages, YouTube videos, images, PDFs, EPUBS, or real-time web search for quick insights.
- 🔍 Smart Vault Search: Search your vault with chat, no setup required. Embeddings are optional. Copilot delivers results right away.
- ✍️ Composer and Quick Commands: Interact with your writing with chat, apply changes with 1 click.
- 🗂️ Project Mode: Create AI-ready context based on folders and tags. Think NotebookLM but inside your vault!
- 🤖 Agent Mode (Plus): Unlock an autonomous agent with built-in tool calling. No commands needed. Copilot automatically triggers vault, web searches or any other relevant tool when relevant.
Copilot's Agent can call the proper tools on its own upon your request.
After months of hard work, we have revamped the codebase and adopted a new paradigm for our agentic infrastructure. It opens the door for easier addition of agentic tools (MCP support coming). We will provide a new version of the documentation soon. Here is a couple of new things that you cannot miss!
- FOR ALL USERS: You can do vault search out-of-the-box without building an index first (Indexing is still available but optional behind the "Semantic Search" toggle in QA settings).
- FOR FREE USERS: Image support and chat context menu are available to all users starting from v3.0.0!
- FOR PLUS USERS: Autonomous agent is available with vault search, web search, youtube, composer and soon a lot other tools! Long-term memory is also a tool the agent can use by itself starting from 3.1.0!
Read the Changelog.
- "Copilot is the missing link that turns Obsidian into a true second brain. I use it to draft investment memos with text, code, and visuals—all in one place. It’s the first tool that truly unifies how I search, process, organize, and retrieve knowledge without ever leaving Obsidian. With AI-powered search, organization, and reasoning built into my notes, it unlocks insights I’d otherwise miss. My workflow is faster, deeper, and more connected than ever—I can’t imagine working without it." - @jasonzhangb, Investor & Research Analyst
- "Since discovering Copilot, my writing process has been completely transformed. Conversing with my own articles and thoughts is the most refreshing experience I’ve had in decades." - Mat QV, Writer
- "Copilot has transformed our family—not just as a productivity assistant, but as a therapist. I introduced it to my non‐technical wife, Mania, who was stressed about our daughter’s upcoming exam; within an hour, she gained clarity on her mindset and next steps, finding calm and confidence." - @screenfluent, A Loving Husband

Why isn’t Vault search finding my notes?
If you're using the Vault QA mode (or the tool @vault in Plus), try the following:
- Ensure you have a working embedding model from your AI model's provider (e.g. OpenAI). Watch this video: AI Model Setup (API Key)
- Ensure your Copilot indexing is up-to-date. Watch this video: Vault Mode
- If issues persist, run Force Re-Index or use List Indexed Files from the Command Palette to inspect what's included in the index.
⚠️ Don’t switch embedding models after indexing—it can break the results.
Why is my AI model returning error code 429: ‘Insufficient Quota’?
Most likely this is happening because you haven’t configured billing with your chosen model provider—or you’ve hit your monthly quota. For example, OpenAI typically caps individual accounts at 120ドル/month. To resolve:
▶️ Watch the "AI Model Setup" video: AI Model Setup (API Key)- 🔍 Verify your billing settings in your OpenAI dashboard
- 💳 Add a payment method if one isn’t already on file
- 📊 Check your usage dashboard for any quota or limit warnings
If you’re using a different provider, please refer to their documentation and billing policies for the equivalent steps.
Why am I getting a token limit error?
Please refer to your model provider’s documentation for the context window size.
- Max tokens refers to completion tokens, not input tokens.
- A higher output token limit means less room for input!
🧠 Behind-the-scenes prompts for Copilot commands also consume tokens, so:
- Keep your message length short
- Set a reasonable max token value to avoid hitting the cap
💡 For QA with unlimited context, switch to the Vault QA mode in the dropdown (Copilot v2.1.0+ required).
