Tellhouse: a household coordinator that removes the friction from daily tasks.

Tellhouse is the house that remembers. Everyone in the circle tells it things once: what is running low, what needs picking up, and what a person who needs support has asked for or been promised. The house keeps one shared record of all of it, promises included, recorded as Claims, so someone waiting can see that someone is coming. It passes each thing to the person it names; not everyone hears everything.

Tellhouse coordinates a household: it records, reminds, and relays between the people in its circle. It does not give medical advice, diagnoses, or treatment recommendations; anything health related is written down in the person's own words and handed to a person.

In households looking after one of their own, the person who knows first what is needed is the person who needs support, and most tools give her no way to speak into the system. Tellhouse hands her the front door: she tells the house, and once a person confirms her telling, what she asked to pass on reaches the person it names.

Tellhouse is for any household supporting an adult family member, and for the circle it chooses: family, friends, neighbors, and sitters. Millions of households run this coordination on group texts and memory.

How it works. A person tells the house by voice or by typing. Muse Voice Transcribe turns speech into text; Muse Spark routes each telling to the person it names or onto the shared record. SAM 3.1 checks a photo of the supply shelf, so the shelf's state is seen, not remembered. In the evening Muse Wonder reads the day back and flags clashes and Claims still not done. A household-visible message relayed to an adult gets a Muse Image picture card in the recipient's inbox, so it reads at a glance. Nothing consequential happens until a person confirms it: an agent proposes, a human confirms, a written record of both.

Privacy is built into the shape of the thing, not added on. A telling marked private, or one that touches health, never reaches a model at all. A plain reader writes it down in the speaker's own words and hands it to a person. Messages cross a sealed relay that cannot read what it carries.

Children in the household are members the adults talk about, like "I will get Mia at 3." They are not users: they have no view of their own, they send nothing to the house, and no model output is made for them or sent to them.

The idea comes from how one household already keeps each other informed. The code, data model, and demo were built during the event, October 26 to November 4, 2026, by one developer. The demo household is invented: Margaret, Daniel, and Lisa Ellis and their children Timmy and Mia; no real family's information is in it.
