This Neovim plugin integrates GitHub Copilot Chat, offering AI-powered coding assistance directly within the editor. It targets Neovim users seeking to leverage advanced LLMs like GPT-4o and Claude 3.7 Sonnet for code explanation, review, optimization, and more, with rich workspace context and customizable interactions.

How It Works

The plugin utilizes a modular provider architecture, supporting official Copilot Chat and custom LLM backends (Ollama, LM Studio, Mistral.ai). It features a smart embeddings system for rich workspace context, allowing explicit context sharing via visual selections or specified inputs. An interactive chat UI with completion, diffs, and quickfix integration, coupled with a powerful prompt system using composable templates and sticky prompts, enhances user control and workflow.
