From the README

# AI Second Brain

A knowledge base that an AI agent builds and maintains for you, in plain
markdown files you own. Everything you read, watch and save gets turned into
linked wiki pages, connected to everything already there, and you can ask it
questions.

This repo is the full version of the guide: the concepts, the setup, the vault
template, the agent skills, the scripts, and the resources. Free, no signup,
nothing to install beyond Obsidian and an agent.

**Read it on the web:** [undefined-ui.github.io/second-brain-os](https://undefined-ui.github.io/second-brain-os/) — the full guide with search and navigation, plus [every vetted link](https://undefined-ui.github.io/second-brain-os/resources.html) in one filterable page.

## The problem it solves

You save things with the intention of coming back. You never do. Bookmarks,
screenshots, read-later queues and half-filled Notion pages accumulate without
compounding, because filing and linking them is boring work that humans stop
doing
