What is it?

CopilotChat.nvim is a Lua plugin for Neovim that opens a chat window where you can talk to GitHub Copilot models without leaving the editor. You reference context with a few inline markers: #buffer for open buffers, #file for a specific path, #gitdiff for staged or unstaged changes, #url for web pages, and #selection for the current visual selection. Predefined prompts such as Explain, Review, Fix, Tests and Commit cover common code tasks, and you can define your own prompts and functions in the setup config.

The chat supports tool calling through @copilot, which lets the model run functions like file reads, glob, grep, git diff and bash. Tool calls require manual approval by default, and you can mark specific tools or groups as trusted. Besides the Copilot provider, it can be configured with custom providers such as Ollama and Mistral.ai, and it offers a Lua API for scripting and headless use.

Key features

  • 01Chat with GitHub Copilot models such as GPT-4o and Claude Sonnet from Neovim.
  • 02Add buffers, files, git diffs, URLs and selections to a prompt with #-references.
  • 03Let the model call workspace tools with manual approval or trusted auto-run.
  • 04Reusable prompt templates for explain, review, fix, tests and commit messages.
  • 05Save and load chat history, and add answers or diffs to the quickfix list.
  • 06Lua API for automation and headless operation.
