LLM Wiki

A pattern for building personal knowledge bases using LLMs.

This is an idea file, it is designed to be copy pasted to your own LLM Agent (e.g. OpenAI Codex, Claude Code, OpenCode / Pi, or etc.). Its goal is to communicate the high level idea, but your agent will build out the specifics in collaboration with you.

The core idea

Most people's experience with LLMs and documents looks like RAG: you upload a collection of files, the LLM retrieves relevant chunks at query time, and generates an answer. This works, but the LLM is rediscovering knowledge from scratch on every question. There's no accumulation. Ask a subtle question that requires synthesizing five documents, and the LLM has to find and piece together the relevant fragments every time. Nothing is built up. NotebookLM, ChatGPT file uploads, and most RAG systems work this way.

Multitenancy refers to a principle in software architecture where a single instance of the software runs on a server, serving multiple client-organizations (tenants)

Let's start by enumerating some multi tenant applications and understand how they handle it.

// Now, there are instances where you don't actually care about parameters passed in. A GET route to an about page for example. 
// The normal route might look like:

  Get["/"] = parameters => View["about"];
      
// However, since parameters are not used, the convention is to use an underscore:  

  Get["/"] = _ => View["about"];

// That works, but, frankly, it's a little hard to read and gets lost in the shuffle.
