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
