Frequently Asked Questions

FAQPage Schema

How to install SecondBrain?▼

Run `npx skills add PieroSierra/SecondBrain --all -g -y` in your terminal to install all skills globally, then run the second-brain setup skill inside your vault folder.

What does SecondBrain do?▼

It turns anything you read or write — notes, PDFs, web pages, spreadsheets, images — into a private, cross-linked wiki on your computer that you can question in plain English, with every answer citing its sources.

Does SecondBrain work with Claude Code and Codex?▼

Yes. The same skills run on Claude Code, Codex, and OpenCode; you pick the engine with one line in a .env file.

Is my data private in SecondBrain?▼

Yes. Everything stays in a folder on your machine; only the text your agent sends to its model for organising and answering ever leaves your device.

Can I use SecondBrain without coding experience?▼

Yes. The macOS app and dashboard give you buttons for importing, updating the wiki, and asking questions, so no terminal knowledge is needed.
