i built an AI that
lives in my house.

senior business analyst by day. at night i run sparky — a local AI resident on a DGX Spark that grinds a task board while i sleep, remembers my family, speaks in my airpods, and answers to a written constitution.

the resident

sparky isn't a chatbot. it's a housemate with a job.

one memory, many roles, running entirely on hardware i can point at. not a saas subscription wearing my name — a resident that knows the house, earns trust, and leaves receipts. and when it wants something new, it proposes — i hold the pen.

memory soul

opens every conversation already knowing the house. idle chats get swept into memory nightly, and it writes a first-person journal of its day — every line inspectable, auditable, deletable.

the board

a kanban where autonomous workers claim tasks and grind. fire off work, walk away — the phone buzzes when it's done or stuck. sparky can even spawn its own helpers — one level deep, by design, with receipts.

🎙voice

its own voice (elevenlabs), ears that never leave the house (local whisper). airpods, apple watch, desktop — hold to talk, or just talk.

the trust ladder

autonomy is earned, not defaulted. every action lands in one ledger, and permissions widen per-domain only when the record is clean. when it needs a yes, it asks on my lock screen — i answer from the watch.

household aware

knows who's speaking. family members get their own roles and boundaries — my kid can chat with it; my kid cannot nuke the task board.

home senses

reads the house through home assistant — sensing first, always. control only ever arrives behind allowlists, policy, and audit.

mastering the process

i don't write most of the code.
i run the org that does.

sparky is built by a team of AIs with separated powers — and the separation is the whole trick. builders build. reviewers review. nobody holds both pens. i sit where a founder sits.

founder

ben — the human

writes the wants, not the how. owns the taste, the product calls, and the standards. validates every slice against reality, not vibes.

architect

fable — reads every diff

the standing seat: writes the specs, reads every diff, runs the tests, keeps an append-only decision log (80 entries and counting) — and drafted the constitution the others answer to. can reject. does reject.

builder

codex — owns the iphone app

builds the phone + watch client end-to-end, and only talks to the platform through a written api contract. when the contract lies, it files a seam report — and gets a ruling, not a workaround.

builders

the coders — hired per slice

disposable AI sessions, one bounded slice each, in isolated worktrees. tests green, review passed, then gone. no drive-by refactors, no scope creep.

the previous build — my first agent — rotted into 20,000-line files and died of its own success. the rebuild got a constitution instead: intake rules, review doctrine, a trust ladder, an append-only decision log. two hundred reviewed slices later: no file over 500 lines, every action audited, zero mess. speed didn't drop. speed is the reward.

the footprint

one small gold box in kentucky.

everything runs on a DGX Spark — 128gb of unified memory humming on a shelf — reachable from my pocket over a private mesh. nothing leaves the house.

selected work — polished, weird, or somewhere in between.

process

how i actually build. not glamorous.

01

the idea spiral

get an idea, overthink it, hate it, come back to it, decide if it has pull.

02

write the want, not the how

a clear paragraph of intent beats a fake technical design from me every time. the spec is the product decision — the implementation is negotiable.

03

run the org

a builder agent ships one bounded slice. an architect agent reviews the actual diff. tests must pass, everything leaves a record, and i validate against the live system — not the report.

04

guard the speed

scope creep dies in review. stalled experiments get deleted, not absorbed. moving fast forever is the reward for staying clean.

i didn't come up through computer science — i came up through workflows, friction, and "why is this more annoying than it should be." turns out that's exactly what it takes to direct engineering-grade AI: knowing precisely what you want, insisting on standards, and never confusing output with progress. the agents type faster than i ever will. the judgment is mine.
