Show HN: qc-ai – Quick Config for Neovim with OpenAI

4 months ago 23

Natural language Vim config powered by AI.

qc-ai is a super lightweight Neovim plugin that lets you configure your editor using natural language prompts like:

:QC use a light theme and turn on line numbers

:QC optimize for viewing large files

You get the idea.

This uses OpenAI’s API to generate and apply valid Lua code that dynamically configures your Neovim environment. Perfect for those moments when you don’t remember the exact Lua syntax.

Instantly apply settings via natural language (:QC)
Caches responses to avoid redundant API calls
Remembers previous conversations (limited to recent history)
Saves history and cache to disk across sessions
Configurable model, temperature, and history length
Commands to clear history and cache

Neovim 0.8+
OpenAI API key in your environment:

export OPENAI_API_KEY="sk-..."
