## What it is
LSP-AI is an open-source language server written in Rust that acts as a backend for AI-powered editor features like LLM chat and code completions. Because it implements the Language Server Protocol, it works with any LSP-capable editor such as VS Code, NeoVim, Emacs, Helix, and Sublime.

## Use cases
- add ai code completions to neovim or helix
- self-hosted alternative to github copilot
- chat with llms inside my code editor
- use local llama.cpp models for autocomplete
- custom ai refactoring actions in emacs
- integrate openai or mistral into any lsp editor

## When to choose
- you use an LSP-capable editor and want AI completions or chat without switching tools
- you prefer local or self-hosted models over cloud services
- you want a Copilot alternative that works across many editors

## When to avoid
- you want a polished turnkey product with active new feature development
- you need an IDE plugin with rich UI rather than a language server backend
- you rely on fast completions without a fast backend model or provider

## Facets
- artifact type: service
- maturity: maintenance
- function: llm-inference, chatbot, developer-tools, plugin-system
- domain: developer-tools, large-language-models, text-editors, self-hosted
- platform: cross-platform, cli, editor-plugin
- tags: lsp, language-server, code-completion, ai-copilot, editor-integration, local-llm, llamacpp, openai
