Friday is a personal AI that learns from your digital life — email, calendar, documents, health data, habits — and builds a private model of how you actually live and decide. Instead of waiting for prompts like a chatbot, Friday works in the background: spotting patterns across your history, flagging decisions that look like past mistakes, protecting your time, and handling routine tasks on your behalf. It's built on a personal knowledge graph that fine-tunes on your own data, so it gets more useful the longer you use it. Data encrypted, with granular permissions over what it sees and what it's allowed to do. Not an assistant. A second brain that runs alongside yours.
