- 🖼️ 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.

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!
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/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).
