About Obsidian Copilot

FreemiumIntermediateAPI availablePlugin · Desktop

Obsidian Copilot is the leading AI plugin for Obsidian, turning your vault into a knowledge work agent. With over 100,000 users and 1.5M+ downloads, it lets you chat with your notes using any LLM (OpenAI, Anthropic, Google, local via LM Studio/Ollama, or any OpenAI-compatible model). The newly released v4 agent mode introduces autonomous multi-step reasoning and tool use, enabling AI agents that can search the web, read documents, and maintain long-term memory. Deep Obsidian integration means everything is a Markdown file – chat history, system prompts, custom commands – giving you full ownership and portability. The free plugin is open-source and works with your own API key; Copilot Plus ($11.67/mo yearly) adds a built-in chat model, smarter vault search, AI agents, PDF/EPUB support, and project workspaces. For maximum privacy, Self-Host Supporter ($349.99 lifetime) allows running your own models. No other Obsidian AI plugin offers this combination of flexibility, agentic capabilities, and file-over-app philosophy.

Behind the Verdict

Obsidian Copilot isn't just another AI chat plugin – it's the most complete AI integration for Obsidian, and v4's agent mode makes it even more powerful. We'd reach for this when we need to search, summarize, and generate content without leaving the vault. The free tier (BYOK) already gives you solid chat and search, but the Plus tier is where it shines: built-in model, web-search agents, and project workspaces. Where it bites: you must use Obsidian, so standalone chatbot seekers should look elsewhere (e.g., ChatGPT, Claude). Compared to alternatives like Smart Connections or Text Generator, Copilot offers a richer feature set – agents, projects, composer – but requires more setup. In practice, the agent mode is still evolving; early adopters should expect some rough edges. For privacy-conscious users, self-host mode is a standout, but it's a one-time $350 fee. Overall, Copilot is the best choice for Obsidian power users who want an all-in-one AI assistant.
