Braain is the shared brain for your family — an AI-powered space that remembers everything, coordinates everyone, and quietly handles the mental load no one has time for. Tell it once. It remembers forever. A soccer practice. A doctor's appointment. The babysitter's number. The Wi-Fi password. The kids' medication routine. Braain captures it, files it, and surfaces it to the right person at the right moment. WHAT BRAAIN DOES • A shared family calendar with two-way Google Calendar sync • Tasks and reminders, routed to the right person • A searchable home for notes, instructions, and household info • An AI agent that learns how your family runs — and offers to help without being asked • Proactive check-ins ("every Sunday, plan the week ahead") • Voice-first capture — just talk, Braain figures out what to do BUILT FOR HOW FAMILIES ACTUALLY WORK No more "who's picking up the kids?" group chats. No more sticky notes that disappear. No more apps that take three taps to add one thing. Braain is built around a single idea: tell the AI once, and it handles the rest. PRICING Start free.
