Grandma Buddy is a voice companion for an older adult who lives alone. I built it for my grandma, who is lonely, struggles with her phone, and lives with a lot of pain. She just talks; she never types. Every day Buddy checks in on how she feels, reminds her to take her pills, keeps a symptom diary in her own words, writes plain notes for her next doctor visit, sends a short update to the family member she chose, and checks suspicious letters and messages for scams. It also finds her glasses or keys in a photo of the room, reads her letters and bills aloud, paints a Memory book from the stories she tells, and sends a painted postcard to her grandkids. The AI never gives medical, mental-health, or food advice. A rules-based safety net runs before any AI call on every message: emergency words open a fixed "call 911" screen, poison words open Poison Control, crisis words open a calm screen with 988 and her family. Those screens are plain text, never written by a model. When she asks for advice, Buddy says it can't and offers to call her doctor or family, or to save a question for her doctor. A second check reads every reply before it is spoken. Everything runs on her own computer, with big type, big buttons, one main action per screen, and everything read aloud in a natural local voice. A family page lets her daughter see her day, message her, and get notified if a pill is missed. 850 automated tests and a 42-turn evaluation at three reasoning levels are in the repo.
