Copilot Makes Obsidian the Knowledge Worker's IDE
Rewritten end to end. Copilot V4 puts frontier agents natively inside Obsidian.
Bring your own Claude or ChatGPT subscription and use Copilot for free. The plugin is open source, and each way of bringing your own AI maps to an agent that runs natively in your vault:
| You have | Copilot runs |
|---|---|
| Claude subscription | Claude Code |
| ChatGPT subscription | Codex |
| API keys or local models (OpenAI, Google, Ollama, LM Studio, and more) | opencode |
Prefer not to juggle API keys? The new Lite plan runs opencode on Copilot-hosted models with enterprise-grade privacy for $7.99 a month, and unlocks most paid features.
Provider terms and usage limits still apply.
V4 is an entire rewrite. Instead of a single built-in assistant, real agents plan, search, use tools, and write results back to your notes.
- Speaks fluent Obsidian. Agents write wikilinks, canvases, and Markdown. The work lands in your vault and stays linked to everything around it.
- Tabs, like a browser. Open a different agent in each tab and work several threads at once: one summarizing a paper while another reorganizes your inbox.
- Project Mode, scoped to the work. Give an agent its own project, with a per-project
AGENTS.mdthat steers how it behaves inside that project. - Quick Ask, without leaving the page. Assign a shortcut in Hotkeys (we recommend
Ctrl/Cmd+K) and trigger an inline, turn-by-turn window right from the note area, so you can ask a quick question without losing your place. - Finds that vague thought instantly. Ask in half-remembered language and Copilot searches your vault by meaning, powered by Miyo, our local indexing engine.
- Any model, zero lock-in. OpenAI, Anthropic, Google, Ollama, LM Studio, or any OpenAI-compatible endpoint. Switch whenever you want.
- One setup, every agent. Add a skill once, then enable it across opencode, Claude Code, and Codex.
"Where's that note about attention only reading some of the tokens?"
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]].
Important
Multi-agent collaboration is a Copilot Plus feature, included for Plus subscribers and Supporters.
Mention several agents in one prompt and each works it in parallel. Copilot combines their answers into a single result, so you get three perspectives for the effort of one question.

"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."

More from the community
"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."
Brad Decker, CTO, Concierge Auctions
"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."

How is V4 different from previous versions?
V4 rebuilds Copilot from scratch, with agents as the main interface instead of a single built-in assistant. Frontier agents run natively inside your vault with full tool use, and around them V4 adds tabs for parallel sessions, Project Mode with its own AGENTS.md, and skills you configure once and share across every agent.
What does a license add?
Built-in models with zero setup, multi-agent collaboration, a web-search backend built for agents, PDF parsing that preserves tables and layout, built-in skills such as YouTube and X capture, and Symposium, which publishes a note as a shareable webpage in one click. Lite covers most of these at the lowest price; multi-agent collaboration is included with Plus and Supporter.
I'm a V3 user. What happens to my setup?
V4 arrives as a normal plugin update. Your settings, custom prompts, API keys, and existing Copilot Plus license carry over, and Quick Ask plus vault QA keep working as before.
How is my data handled?
Your notes remain plain files in your vault, and the search index is stored locally. On the free tier, requests go only to the model provider you configure. Licensed features may use Brevilabs services for the processing you explicitly request. See the disclosure below and the privacy policy.
