Copilot for Obsidian

Copilot for Obsidian is an AI tool (by Brevilabs) that adds a conversational agent to Obsidian so students, researchers, writers and knowledge teams can work with their notes without leaving the vault. It bills itself as the number one Obsidian AI plugin, with more than 2.5 million downloads.

How does Copilot find the notes you need?

You can ask for an idea the way you remember it, in loose words, and the agent runs a semantic search by meaning. Indexing is handled by Miyo, a local desktop app from the same team that also embeds outside PDFs and EPUBs, so related notes surface on their own next to what you are writing.

What can it write inside the vault?

Agents work in Obsidian's native format: wikilinks, canvases and Markdown. Output lands as notes and maps you keep, not a chat log that scrolls away. It also offers:

• Projects with their own context, Quick Ask and commands on selected text.
• Local PDF parsing plus YouTube and X thread capture on licensed tiers.
• Multi-agent collaboration that returns a single summary.
• One-click publishing of a note to a public link with OpenArtifacts.

Copilot for Obsidian pros and cons

Model freedom is the big win: it runs on OpenAI, Anthropic, Google, LM Studio, Ollama or any OpenAI-compatible endpoint, with your own keys or your ChatGPT or Claude account, and one skill setup works across opencode, Claude Code and Codex. Project-hosted models run on DeepInfra in the US with zero data retention and no training use. On the flip side, it only makes sense if you already use Obsidian, advanced search depends on installing Miyo and answer quality varies with the model you connect.
