About ChatGPT-MD
ChatGPT MD is an open-source plugin that integrates ChatGPT directly into the Obsidian note-taking environment. It allows users to chat with AI models within their notes, reference other notes using Obsidian's [[wiki links]], and keep all conversation data stored locally in their vault. The plugin supports provider reliability improvements, agent-based personas (such as a writing coach or code reviewer), and tool calling capabilities that enable the AI to search the vault, read notes, and browse the web—with user approval required for each action. It is designed for users who want a seamless AI writing companion while maintaining full control over their data.
