Overview

chat.md is a Visual Studio Code extension that reimagines AI interaction through plain text files with .chat.md extension. Unlike ephemeral web interfaces, chat.md treats conversations as files that can be edited, version controlled, and shared. The extension supports multiple AI providers (Anthropic Claude, OpenAI, custom APIs) and implements MCP as a client to enable tool calling with any LLM. It features non-linear editing, file attachments, conversation templates, and Git-friendly tracking.

Try asking AI

After installing, here are 6 things you can ask your AI assistant:

you:Code debugging and optimization with AI assistance
you:Technical documentation creation through iterative conversation
you:Multi-model AI collaboration without vendor lock-in
you:Which AI models does chat.md support?
you:Can I edit AI responses?
you:How does MCP integration work?

When to choose this

Choose this when you want editable, version-controlled AI conversations stored as regular files in your workspace, especially if you work with multiple LLM providers.

When NOT to choose this

Don't choose this if you need real-time voice conversations or if you prefer web-based AI interfaces over file-based solutions.
