A Coding Partner Who Knows Everything About Your Code

What if you could have a coding partner who knew every single line of code in your project? Well, I have been developing a tool that does exactly that. It uses a AI technique, such as RAG, allowing you to ask complex questions and get immediate answers.

So, how does this magic work?

It is all in a two-step process. First, the AI agent performs a meticulous scan of your codebase. It reads through the files, breaks them down into smaller, logical chunks, and for each piece, it creates a summary. All of this beautiful data (the code chunks and their summaries) is then stored in a local vector database. This creates a rich, searchable knowledge base of your project. And, of course, for complete privacy and control, the entire system runs locally with Ollama.

Once this preparation is done, you can begin the conversation. For instance, you could ask, How is the authentication middleware implemented? or Show me where the database connection is configured. The RAG (Retrieval-Augmented Generation) system retrieves the most relevant information from its knowledge base and uses it to generate a clear, accurate answer.

This tool gives you a powerful coding partner to help navigate complex projects with more speed and less friction. This project of mine is built with Node.js, TypeScript, and LangChain.JS, and you can interact with the AI through a simple API.
