An open-source, local database which collects all your personal data, hooks it to an LLM (BYO), and gives you an assistant that can answer any question about your life.

It also allows you to vibe-code (or just code) small apps on top of your data (e.g., your custom dashboard for your expenses).

I have a short demo here: https://www.youtube.com/watch?v=gqAyvENDjSA
