Obsidian Copilot is an AI assistant plugin for Obsidian that brings conversational AI directly into your note-taking vault. It allows you to chat with multiple large language models, create and execute custom prompts, and edit notes through natural conversation, all without leaving your workspace.
The plugin distinguishes itself by offering complete model flexibility, supporting OpenAI, Anthropic, Google, local, and self-hosted models with no vendor lock-in. It stores all chat history, system prompts, and custom commands as plain Markdown files in your vault, ensuring full data ownership and portability. An autonomous AI agent can independently perform multi-step tasks like vault search, web search, and YouTube analysis, while long-term memory maintains conversation context across sessions.
Beyond chat, the tool provides AI-powered vault search using semantic meaning, automatic discovery of related notes, and the ability to create project-specific contexts from folders and tags. It supports multimedia analysis of images, PDFs, EPUBs, and web pages, and offers customizable AI workflows that can be triggered from the command palette, right-click menu, or keyboard shortcuts. For users prioritizing privacy, all search indexes and chat data remain local, with support for self-hosted models that keep data processing on-device.
