Families run on information that has no API, so parents become human routers. FridgeGraph began with an August 11 text from my friend Tori, a single mother: “An assistant built specifically for single moms.” That sparked a bigger question: what if the infrastructure enterprises use to coordinate complex systems could help families coordinate care? Modern families span households, calendars, schools and phones. Single parents, divorced co-parents, grandparents raising grandchildren, and trusted caregivers all carry pieces of a child’s day. The coordination burden often falls on one exhausted person. FridgeGraph connects that fragmented village around the child. Its shared-fridge interface brings family updates and moments together. Rosina, the AI co-pilot, helps turn information into a plan: read a school notice, identify a scheduling conflict, consult permitted family facts, and prepare a pickup request for the parent to review. Rosina prepares. Parents decide. In the demonstrated school-notice journey, confirmation creates a saved pickup request whose same ID appears in Rosina, Today and Mission Control. Calendar changes persist after reload and leave an Activity record. Judges can switch perspectives to inspect what each caregiver is allowed to see and do. Orbit Alert extends that connected village to a more urgent moment: when a parent cannot locate a child or needs a check-in. It provides one parent-controlled place to prepare an alert, review trusted recipients, coordinate responses and close the alert as “Found safe.” It is private village coordination, not location tracking or an official emergency-alert service. Underneath, Apollo Federation connects seven domain subgraphs: Village, Access, Coordination, Schedule, School, Transport and Activities. Authorized tools, server checks and Supabase row-level permissions connect AI assistance to real records while preserving family boundaries. Meta Muse powers reasoning, transcription and creative invitation artwork; Muse Wonder also contributed extensively to development, diagnosis and verification. Built during the hackathon, FridgeGraph combines a human story with a working, auditable system. The hosted demo uses fictional families and requires no installation. Its six-step guide makes the core journeys easy to test. Typed Rosina is the verified interaction path; a faster hybrid voice integration remains experimental, and live SMS is outside the judged path. The goal is simple: less invisible project management for parents, more time to be present with their families.
