Copilot for Obsidian
The Knowledge Work Agent Designed for Your Second Brain
Animated demo of Copilot Agent Mode in Obsidian: an agent powered by Opus 5 reads a week of captured readings, folds them into evergreen wiki notes, and flags a claim that newer sources contradict.
From notes to knowledge.
The workflows that make a vault compound: search that understands you, agents that speak Obsidian, and the freedom to run it all on any model.
The free plugin runs on your existing ChatGPT or Claude subscription, or your own API keys. You never have to pay us to use it.
Ask for it the way you remember it, half an idea in plain words. Your agent searches your vault by meaning and comes back with the exact notes.
Found it in [[Sparse attention]]:
Attend to a learned subset of tokens instead of the full window: quality holds while compute drops.
You also captured this in [[2026-08-03 Native sparse attention]] and [[2026-08-01 Longformer revisited]].
Agents write in your vault's own language: wikilinks, canvases, plain Markdown files. Work lands as notes and maps you keep, not chat transcripts that scroll away.
Use OpenAI, Anthropic, Google, LM Studio, Ollama, or any OpenAI-compatible endpoint. Your own keys and custom providers run through the opencode agent, and you can switch models anytime.
Add a skill once, then flip it on per agent: one control surface across opencode, Claude Code, and Codex. No copying configs between tools.
Related notes surface automatically beside whatever you're writing, ranked by meaning. The index behind it is powered by Miyo, our local indexing engine that embeds your notes along with outside PDFs and EPUBs, so connections appear before you go looking.
Premium
Upgrade to a workflow that holds up.
The free plugin is yours forever, on your existing ChatGPT or Claude subscription or your own API keys. A license adds the managed layer: models, search, parsing, and skills that work the moment you open Copilot.
Models Included
Built-in chat models come with the license. Open Copilot and start working. No provider account, no API key.
Multi-Agent Collaboration
Put several agents on the same question and they come back with one summary. Different perspectives on the same subject, without running each agent yourself.
Symposium: One-Click Publish
Publish a Markdown note as a shareable webpage in one click. Share one link, then push new versions until everyone is on the same page.
Better Web Search
Your agents search the web through a backend built for them, not for browsers. More signal per query, so research lands on better sources.
Better PDF Parsing
PDFs become text your agent can work with, tables and layout included, ready to cite into your vault.
Built-In Skills: YouTube, X, and More
Knowledge-work skills run out of the box, including capture of YouTube videos and X threads straight into your notes. No setup required.

Investor & Research Analyst
The first tool that truly unifies how I search, organize, and retrieve knowledge without ever leaving Obsidian. My workflow is faster, deeper, and more connected. I can't imagine working without it.
CTO, Concierge Auctions
I drop meeting transcriptions, personal notes, and architecture ideas into my vault. Copilot gives me a personal assistant that finds missing puzzle pieces and surfaces relevant info during live calls, no manual searches.
Professional Writer
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.
Course Creator
Obsidian + Copilot gives you superpowers while keeping your work in your vault. I use it for course creation, active learning, and vault hygiene, saving me hours at higher quality. Everything stays mine.
Executive VP, ZebPay
Nothing can substitute for Copilot's ability to work with my Obsidian notes. I don't think any other community plugin comes close.
Writer & Journaler
Obsidian with Copilot is now my main text editor. Custom shortcuts let me fix grammar or run commands on highlighted text without ever switching apps. It makes my whole workflow dramatically more effective.
Founder/CEO, MIANCORE Productions
Your plugin is exactly what I have been looking for and would truly finalize my current workflow in Obsidian. I've set my mind on using it.
CISO for a SaaS company
I can quickly summarize YouTube videos and integrate them into my second brain. Often I use it as my primary intelligence-gathering tool. Nothing else quite matches it in capability.

UX Designer & Dad
I introduced it to my non-technical wife 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.
PKM Practitioner
It's the first tool I've tried that actually makes 'thinking in Obsidian' feel fluid. I've been using it regularly and genuinely want to be a long-term supporter. I'm excited about what you're building.
Engineer at Google
Copilot for Obsidian feels like the perfect tool to streamline my note-taking, increase productivity, and enable me to connect ideas more efficiently. Thank you for developing such a fantastic tool.
Global VP of Shared Services
Massive fan of your work. You're onto something big here.
Software Engineer
I dump architecture decisions, PR notes, and meeting summaries into Obsidian. Copilot recently surfaced a design decision I made 8 months ago that was directly relevant to a current bug. That alone paid for the subscription.
Independent Consultant
Client knowledge doesn't live in my head. It lives in my vault. Copilot lets me walk into any engagement and instantly surface insights from previous clients facing the same challenges. It's changed how I deliver value.
Research Scientist
Asking questions across 5 years of annotated papers and research notes has completely changed how I approach new work. It's like having a conversation with my past self. No other tool comes close for academic workflows.
Product Manager
My vault is my product brain: user research, competitor analysis, roadmap rationale. Copilot lets me ask 'what did users say about X in Q3?' and get a real answer. The institutional memory you can't keep in your head.
