#16 Build With Intention | Building a Second Brain with AI

Hello Reader

A few weeks ago, Andrej Karpathy shared how he uses LLMs to build personal knowledge bases, compiling raw documents into structured, interlinked wikis.

I loved the idea. So I built the tool.

Intention

Here's the problem most of us have:

Knowledge is scattered. Bookmarks, PDFs, notes, saved articles, things we meant to revisit but never did.

And every AI conversation starts from zero. It doesn't remember what you asked yesterday. Nothing compounds.

What if you could change that?

Insight

I built Wikimind: an open-source CLI that turns raw documents into a living knowledge base.

Drop files in. Get a wiki out.

It ingests your sources, extracts concepts, generates linked articles, and lets you query your own knowledge in natural language.

The more you feed it, the smarter it gets. Connections you missed. Patterns across hundreds of notes. A second brain that actually remembers.

Inspired by Andrej's pattern. Built with TypeScript and Claude. Open source.

​GitHub →​

npm install -g wikimind

Action

Most people's knowledge disappears into folders they never reopen.

What if yours was compounded instead? Try the tool and make your own personal knowledge bases.

A Note

If you're building with AI and want help thinking through systems and workflows - I'm opening a few coaching spots.
