One agent, the whole household

Most of Dustav is about one person and their agent. But an agent can belong to a household — one shared agent the whole family runs its life with, that knows everyone in it. This isn't a separate product or a bundle of accounts stapled together; it's the same agent, the same glass box, with the family woven in. This page explains the shape of it.

The household is the unit

The obvious way to build family support is to give everyone their own agent and let the agents talk to each other. We built the opposite: one shared agent per household. A single Dustav that each member talks to privately, and that holds the family's shared life in one place.

That choice is the whole point. An agent that knows the family — who's in it, what's on the calendar, the texture of the household — is more useful than a swarm of separate agents trading messages. There's one calendar, one set of facts, one place to look, and it belongs to all of you.

A solo agent, in this framing, is just a household of one. The family layer is built additively on top of the same machinery, so nothing about the single-person experience changes.

What's shared, and what's yours

The line between shared and private is drawn deliberately, and it's drawn by kind of thing:

• Shared across the household — the family's facts (the durable household knowledge), the calendar, and the notes. Open the Context tab and everyone in the family can read these. They're the family's, collectively.
• Yours alone — your own conversation thread with the agent, and what it has learned about you specifically (like what to call you). Each member has their own.

So the agent carries one set of household facts that everyone contributes to, while still keeping a personal sense of each person it talks to. (Shared facts & privacy goes deep on exactly what's visible to whom.)

How you talk to it

Every member has their own private conversation with the agent — the normal one-to-one chat, scoped to them. That's the default, and it always works the way a solo agent does: you say something, Dustav answers.

Alongside that, the agent has a family channel — a one-way feed it posts to when there's something the whole household should know. A calendar event got added, a reminder is coming up: the agent broadcasts the logistics, the things a family coordinates on. It does not broadcast confidences — something personal one member told it in their private thread never shows up on the family channel. Tap a post and it opens your private thread, with that post as the starting point. Every real conversation still happens one-to-one.

The practical stuff, shared

The agent's built-in capabilities become household-aware. There's one family calendar everyone reads and writes — the birthdays, the appointments, the recital on Thursday. When an event comes due, the reminder fans out to every member's own thread, so the whole family gets the nudge, not just whoever entered it.

Getting started

A family agent is set up by one adult — the owner. There's no ceremony and nothing to configure: the agent is ready the moment the household exists. Everyone else joins afterward and just starts talking to it — the first time you open your chat, it asks what to call you and you're off. There are two ways to join, depending on who's joining; Joining a family walks through both.
