We delivered a personal AI that holds every detail of a historic Charleston single house — warranties, contractor contacts, maintenance schedules, renovation history, and appliance manuals — and proactively reminds the owner what needs attention before it becomes a problem

A couple who had just closed on an 1890s single house south of Broad came to us overwhelmed by the volume of information attached to owning a historic home. They had a three-inch seller's disclosure packet, a termite bond folder, an HVAC maintenance contract, a sheaf of paint-color notes from the previous owner's restoration, a plumber's business card stuck to the refrigerator, a roofer's warranty certificate buried in a drawer, and forty-seven emails from their home inspector with photos of every crawlspace joist, every junction box, and every flashing detail — none of it organized, none of it searchable, and none of it connected to any kind of calendar that would remind them when the HVAC filters needed changing, when the termite retreatment was due, when the exterior paint warranty expired, or when the chimney was last inspected. They had a spreadsheet started with three rows in it before they gave up. They also had a stack of appliance manuals — some for equipment the previous owner installed, some for pieces they were replacing during their renovation — and no idea which model numbers matched which serial numbers for warranty registration purposes. They wanted one place that knew everything about their house and reminded them what to do next. We built a personal AI that functions as a living homeowner's manual for their specific property. The ingestion layer consumed every document they had. We scanned the seller's disclosure, the inspection report, the termite bond, the HVAC contract, every warranty certificate, every contractor invoice from the renovation, and every appliance manual. The AI extracted structured data from each: contractor names and phone numbers, warranty start and expiration dates, model and serial numbers, service intervals, paint colors and where each was used, materials specifications, permit numbers, and inspection dates. Everything went into a single knowledge layer organized by system — roof, HVAC, plumbing, electrical, exterior envelope, interior finishes, appliances, pest control, landscaping, and foundation. Each system tracks what was installed, when, by whom, what warranty covers it, when it was last serviced, and when it next needs attention. The conversational interface lets them ask natural questions the way a homeowner actually thinks about their house. They can ask which contractor installed the tankless water heater and get back the name, phone number, install date, model number, and warranty expiration. They can ask what paint color is on the dining room walls and get the brand, finish, color name, and color code. They can ask when the roof was last inspected and whether anything was flagged. They can ask what the HVAC filter size is without climbing into the attic to read the unit label. They can ask whether their dishwasher is still under warranty and get a yes-or-no answer with the expiration date and what the warranty covers. The proactive layer runs on a schedule and sends reminders before maintenance is due — not after something fails. Two weeks before the HVAC biannual service window, it reminds them to call their contractor and includes the contractor's number and the service contract reference. When exterior paint approaches year seven of a ten-year warranty, it reminds them to schedule an inspection so any warranty claim happens within coverage. When the termite bond renewal is sixty days out, it reminds them and notes what the annual retreatment costs. When gutters have not been cleaned in six months — based on their chosen maintenance interval — it nudges them. When smoke detector batteries hit their twelve-month replacement window, it reminds them how many batteries and what size. This is not a generic home-maintenance checklist pulled from the internet. Every reminder is specific to their house, their equipment, their contractors, and their warranties. A generic app would tell them to service their HVAC twice a year. Their AI tells them that Johnson Mechanical is due in October for the fall tune-up on the Carrier 24ACC636A003 in the attic, that the last visit was April 12th and the technician noted the condensate line was slow to drain, and that their service contract covers two visits per year with parts included. As they add to the house — a new fence, a repainted bedroom, a replaced garbage disposal — they tell the AI or forward the invoice email, and it updates the relevant system record automatically. The house's digital memory grows with them rather than decaying into forgotten file folders. The couple told us that within the first month it had already saved them from missing a warranty registration deadline on their new range, reminded them of a gutter cleaning they had completely forgotten, and settled a disagreement about whether the guest bath faucet was Delta or Moen when they needed a replacement cartridge. They said it felt like having a property manager for a house they live in themselves.
