One memory for the whole house.
Say it to any assistant you already use. Everyone in the house sees the same list, the same bills, the same numbers. Nothing gets lost.

den is by invitation while it is young. Ask and a person answers. Already invited? Sign in. Here for work instead? den for software developers.
The house remembers, so nobody has to.
"Add milk" on one phone. It is on the other.
Two people, two assistants, one list. You say it to the assistant you already talk to, and everyone in the house sees it. There is no app anyone has to remember to open.
"What is due this week?"
The bills live in the house, with what each one is, who pays it, and the day it goes out. Ask, and the answer comes from what the house knows rather than from someone's memory.
Nothing gets lost
Who took eggs off the list, what the plumber charged in March, which vet you used last time. The house keeps what changed and who changed it, so the answer is there a year later.
Add it once. Then just talk.
den for households is added to Claude one time, from a computer. After that it is there in the Claude app on every phone in the house, and nobody installs anything else.
Tell it things in passing
"We are out of milk." "The plumber is coming Tuesday at nine." "The internet bill went up." Claude keeps each one in the right place without being asked to.
It asks before it removes
Taking someone off the list, or a bill out of the house, waits for a yes. A day like "next Tuesday" is confirmed before it is booked. Passwords are never kept.
https://den.pkslabs.com/mcp/householdsign in, and say "start a house" when den asks
Then open the Claude app on any phone in the house and switch den on for the chat. The guide has the steps.
One house, everyone in it.
You invite the people who live with you by email. They join the house, not a company. What is private to one person stays in its own place, shared only with who needs it.
It is yours to take
Everything the house keeps can be downloaded as ordinary files. Nothing is locked in a format only den can read.
Chats end. den remembers.
