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.

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.

This guide covers how to customize the Steam overlay browser. For example, you install an adblocker like uBlock Origin (or any other browser extension including Sponsor Block and Darkreader), change the default search engine, change the start/new tab page, and more.

Steam uses a modified version of Chromium for its overlay browser, which means you can use many of the same extensions and settings that you would in a regular Chromium-based browser.
