# CopilotChat.nvim

A Neovim plugin that brings GitHub Copilot Chat into the editor, supporting multiple models, tool calling with manual or automatic approval, and a scriptable Lua API for automation.

CopilotChat.nvim brings GitHub Copilot Chat capabilities into Neovim, focused on transparency and user control. It supports multiple AI models available through GitHub Copilot, such as GPT-4o, Gemini 2.5 Pro and several Claude models, plus custom providers such as Ollama and Mistral.ai; the exact model list depends on a user's GitHub Copilot settings.

Its tool calling lets the model call workspace functions, such as reading files, running git operations or searching, with manual approval or automatic execution for tools a user trusts. It provides an interactive chat UI with completion, diffs and quickfix integration, composable prompt templates with sticky prompts for consistent context, and token-efficient history management using tiktoken counting. Automation and headless-mode operation are supported through a Lua API, and it can be extended with custom functions, providers and integrations such as mcphub.nvim.

It requires Neovim 0.10.0 or newer and is licensed under GPL-3.0.
