Copilot V3 is a New Era 🔥

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!

Why People Love It ❤️

• "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

🙋‍♂️ FAQ

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.

⚠️ If you set a large max token limit in your Copilot settings, you may encounter this error.

• 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).
