Obsidian Copilot
AI knowledge work agent for Obsidian: chat, search, and automate your vault with any LLM.
Obsidian Copilot is the strongest AI plugin for Obsidian power users. Its model-agnostic approach and deep vault integration set it apart, and v4's agent mode pushes it ahead of simpler plugins like Smart Connections. The free tier is generous; not for non-Obsidian users.

About Obsidian Copilot
Obsidian Copilot is an AI assistant plugin for Obsidian that turns your notes into a knowledge work agent. It lets you chat with your vault using any LLM—OpenAI, Anthropic, Google, or local models via LM Studio/Ollama. The free plugin runs on your existing ChatGPT or Claude subscription or your own API keys. Copilot is built for thinkers who want AI integrated into note-taking, not just a chatbot. Its multi-agent collaboration puts several agents on the same question for a unified summary, and it writes in Obsidian's language: wikilinks, canvases, and Markdown. Related notes surface automatically, powered by Miyo, a local indexing engine that embeds your notes along with PDFs and EPUBs. Features include Projects mode, Composer for rewriting with diff review, Inline Quick Ask, and custom prompts stored as Markdown. Paid tiers add managed models, advanced web search, PDF parsing, multi-agent collaboration, and more. Self-Host Supporter runs models locally for privacy.
Behind the Verdict
Obsidian Copilot excels at integrating AI into your note-taking workflow. Its model-agnostic design means you can use OpenAI, Anthropic, Google, or local models, avoiding lock-in. The vault search is powerful, with semantic and lexical search, and related notes surface automatically via Miyo. Agent mode v4 autonomously multi-step reasons and uses tools, folding readings into wiki notes and flagging contradictions. The free tier is generous, using your existing ChatGPT/Claude subscription or API keys. Paid tiers add hosted models, better web search, PDF parsing, and multi-agent collaboration. Self-Host Supporter offers lifetime self-hosting for privacy-conscious users. The main weakness: if you don't use Obsidian, it's not for you. Also, the free tier requires external API keys or subscriptions, and paid tiers have quotas. But for Obsidian users, it's the most comprehensive AI plugin.
