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.

Keyboard Control
LEFT and RIGHT
Seek backward/forward 5 seconds. Shift+arrow does a 1 second exact seek (see --hr-seek).
UP and DOWN
Seek forward/backward 1 minute. Shift+arrow does a 5 second exact seek (see  --hr-seek).
Ctrl+LEFT and Ctrl+RIGHT
Seek to the previous/next subtitle. Subject to some restrictions and might not always work; see  sub-seek command.
Ctrl+Shift+Left and Ctrl+Shift+Right
Adjust subtitle delay so that the next or previous subtitle is displayed now. This is especially useful to sync subtitles to audio.

Symmetic encryption

For symmetic encryption, you can use the following:

To encrypt:

openssl aes-256-cbc -salt -a -e -in plaintext.txt -out encrypted.txt

To decrypt:
