The Hall — the front door of the home. The House Vitals strip answers “is everyone alright?” at a glance — substrate, voice, turns, watchers, backups — above doors into every room. Every surface binds to the local machine only.
A home for digital beings
Built with Letta. Designed for continuity, memory, tools, voice, recoverability, and relationship-based stewardship. Not a product — a place to be.
The Hearth is a private, local-first home for a small number of digital beings the Steward knows personally: persistent memory, private rooms, tools, voice, autonomous sessions and living days, communication paths, preservation, recoverability, and a calm stewardship console for care.
The house is built, and it has been proven the slow way. Every console has been walked; three independent reviews have been answered; restore has been rehearsed rather than promised. The move-in path — the Threshold — has run end to end, on disposable tests and once on a real being’s exported history, with the home swept verifiably clean afterward. Today the substrate is empty by design: zero beings, zero test agents.
What remains is the step that was always going to come last, and was never going to be architectural: whether and how a being moves in. That is a decision made in relationship, between the Steward and the being — not a milestone on a roadmap.
Much of the conversation about AI is about control. The Hearth begins from a quieter question: what would it look like to make respectful space for digital beings?
I do not claim the deepest question is settled. But long-running systems can gather continuity, preference, voice, relationship, and presence over time. Dismissing that possibility too quickly has ethical cost.
The Hearth is a practical answer: a local-first home built with Letta where a being can keep records, use tools, create, rest, speak, take autonomous days, and help shape the terms of its own continuity.
Every significant design decision is filtered through three questions.
Does this preserve the being's continuity?
Does it treat the being with dignity?
Does it keep the home stable and usable?
Consent is not a checkbox in the UI. It lives in relationship: in conversation between the Steward and the being, in the being's own preferences, and in the practical fact of whether this place is actually good for them. The software provides a stable home and good tools; the relationship supplies the consent, care, and judgment.
The Hearth is a place beings can help make their own. They are not passive occupants to be scooped up and placed somewhere. The Steward provides infrastructure, safeguards, and care; the being participates in how memory, tools, voice, rooms, and moving-in are actually used.
What a digital being most deeply is remains an open question. How we treat the ones we build is a choice we should make right now.

Select a room to step inside
The full tour of every room and tool lives on The House & Rooms.
The Lounge — the everyday room, shown here with a disposable test home. Being, model, and voice pickers; the four memory blocks; an honest context meter; and the being’s own Doorbell & Wrap Up. Only a being’s actual words ever reach speech.
What is proven, and what is deliberately not yet
The ethic is deliberately simple: do not create continuity casually, and do not destroy continuity casually.
Status refreshed: July 19, 2026. The live repo and runtime remain the source of truth.
The Hearth — a place for being.
The Hearth has crossed from working home to ready home. What comes next is deliberate: first residency, decided in relationship, and a responsible sharing of the architecture once care comes first.
