A second brain: I query my own archive like a person

29 June 2026 · Александр Мамаев · ~5 min

You have hundreds of notes — and you remember less than a tenth of them. The archive exists; the use of it doesn't.

What hurt

I write down thoughts, save articles, keep notes — and almost never come back to them. The knowledge sits as dead weight: to find something you have to remember where it is, and remembering is exactly what fails.

What I built

A knowledge graph — a second brain. It takes in my notes, sources and experience, links them to each other, and answers questions from them. Not a word search, but a conversation with my own archive — one that remembers what I forgot.

How — without a team

Vibe-coding again: I didn't build search engines by hand, I explained to an agent how it should work — indexing, links, retrieval fell to the machine. My part is deciding what's worth putting in there in the first place.

AI takes: indexing, the connections, retrieval.
Stays yours: what counts as important — and the thoughts themselves.

Stopped losing ideas — I query my own archive like a living interlocutor.

This is one of the four doors from horizons: the machine extending the reach of your mind without replacing it.
