A personal AI that lives at your house

This is PuffPAI.

Small, expert AI bots that live on hardware you own. Not one giant AI in a data center.

An AI companion with its own name, its own agent team, and its own memory. Build one to be exactly what you need, or take home the one we built. Either way the model, the memory and the vault sit on a computer in your house. No subscriptions ever.

Good evening, Operator. PuffPAI is awake. Everything you see runs on the box in your hallway.

What's tomorrow look like?

Two things: dentist at 9:40 and Mark's run at 6. The shed camera is still recording.

Private, staying on your device Answered from your vault

It is unrealistic and dangerous to build one giant AI that does everything. That is how you get data centers and mass surveillance. So we build the opposite: small experts, good at your things, running on your hardware, keeping your life in your house.

Two ways to get a Puff

Build your own bot from the base, or take home the one we built. Both ship through the beta today, via GitHub invite; free public downloads arrive with the release.

PATH ONE · BUILD YOUR OWN

Start with BuildBot,
the base.

BuildBot is the base every PuffPAI starts from, and it keeps the contracts: the three zones, the vault, the consent gates, zero telemetry. No build can weaken them.

At setup it says: let's see what we're working with here. It looks at your machine, fits a local model to it, sizes your agent team, and asks what kind of bot you are trying to build. Big box or a laptop, you end up with your bot, not our defaults.

Test the wizard in the beta

PATH TWO · TAKE HOME OURS

Get HomeBot,
the first persona.

HomeBot is the first full persona we built on the base: the household companion. Calendar, smart home, media, your documents, voice, and the self-reliance library, all on the box.

Today HomeBot ships as software through the beta, on a machine you already own. The plug-in appliance is where this is going.

no payments at this time, just a list

Both paths end the same way: you name it, and it introduces itself back.

What's a Puff?

Four things, and none of them live in a data center.

01

A bot you build

An AI bot that you build. It can do anything, but not everything: a small expert in your things, not a giant know-it-all.

02

Three zones, non-negotiable

Every build ships all three, the Vault, the Brain and the Bridge, at a baseline that is always there and always stated. Build any zone out as far as you like: your own firewall, your own vault, your own tools.

03

Works with the internet off

Every PuffPAI keeps working when the internet is off. How much it can do offline depends on how you build it. It never needs the cloud to work.

04

Personalized, deeply

Highly customizable, and it learns your household: it ingests the documents and data you feed it, labels them, and keeps them in the house.

One base.
A family of personas.

Each persona is a subject-matter expert: its own knowledge, tools, agents and abilities, all on the same base. HomeBot is our first full bot build, here now. ReBot is next. The rest are the personas we want to build after that.

A persona is a local model, knowledge packs and tools, and agents for one domain, on the same three-zone base.

Not ready to wait for a whole persona? Its knowledge pack can ride along on one you already run. The self-reliance pack already ships inside HomeBot.

HomeBot

HERE NOW · OUR FIRST FULL BOT BUILD

the household companion

Runs the house day to day: calendar, smart home, media, documents, voice. It carries the self-reliance library too, so water, power, food and repairs are already on the shelf. This is the one in the beta, and the one the waitlist is for.

Try HomeBot in the beta

ReBot

NEXT

self-reliance and quiet defense

Preparedness and personal counter-surveillance, as a bot of its own: the knowledge, the tools and the agents for staying ready and staying private. Its pack already rides inside HomeBot. The full bot is what we are building next.

MedBot

ROADMAP

medical knowledge and eldercare

Medications, interactions and plain-language explanations. Never diagnoses, always informs.

AgriBot

ROADMAP

agriculture and homesteading

Soil, seasons, livestock and the preserving math, for the land you actually have.

LedgerBot

ROADMAP

financial literacy

Budgets, debt and the fine print, worked through without your numbers leaving the house.

CivicBot

ROADMAP

legal and civil rights

Your rights, your leases and your local process, explained before you need a lawyer.

ForgeBot

ROADMAP

engineering and maker

Tolerances, wiring, firmware and the part number you cannot find at 11pm.

The only limit is the hardware you put it on. Off-grid, survival, security, engineering, a clinic's paperwork: build the expert you need.

Ideas, not promises. The order will follow what people actually need.

See it running

Real screenshots, personal details blurred, because that's the point. This is the early build, warts included.

The PuffPAI dashboard showing the day's calendar, house status and a chat panel
The home screen. Weather, the calendar, the house. It greets you before you ask it anything.
The knowledge view listing indexed household documents and offline reference books
The library. Your documents and thousands of reference books, indexed on the box.
The agents view showing which specialist handled each recent request
The agent team, at work. You can see which agent took the question and what it touched.

How it keeps
your stuff yours

Three zones. Your private things, the shared brain, and the one lane that touches the outside world. Everything it learns is about your household, not a demographic it filed you under.

These three zones are the contracts every build keeps. It picks the zone for every request. You never have to.

The baseline is always on, in every build. How far each zone goes is up to you.

ZONE 1 · LOCKED

The
Vault

Your files, notes, camera footage and voice. Anything personal is classified and labeled the moment it arrives, filed into the vault, and wiped from working memory.

  1. 01classified and labeled on arrival
  2. 02filed to the vault, wiped from memory
  3. 03encrypted at rest
  4. 04PIN or fingerprint to open

Even the AI has to ask you. The labels are yours to rename or delete.

ZONE 2 · THE BIG ONE

The Brain

The model, its tool calls, the agent team, the indexing, and the knowledge base: knowledge packs plus a curated offline library of publicly available reference material.

Documents you load are labeled and ingested automatically, so your manuals sit on the same shelf as the reference books. The longer you use it, the more the shelf looks like your house.

ZONE 3 · THE ONE LANE OUT

The Bridge

The internet lane and the house guard, in one place. Weather, traffic and music come in with your identity stripped off the request.

Going the other way it sees every device on the network and manages them, and when you want it to, it acts as a firewall that shuts down the gadgets that tattle. Your TV does not need to report your evening to anyone. A simple firewall is built in, and it can tie into the security gear you already run, routers and firewalls, to go further.

Zero telemetry. Zero phone-home. PuffPAI uses the internet like a utility (weather, music, radio) without reporting you back to anyone. Every outside connection is listed in plain sight and can be switched off. And when the internet goes down, PuffPAI keeps working.

Puff, the PuffPAI cloud

Why we built it

We love security and privacy. We believe they are the foundation of a free nation.

Everyone is building so much cool stuff right now. We wanted a foundation where you can plug any of it in (models, voices, personas, new abilities) and end up with an AI that is personalized, private, and actually yours. Plug and play. Customize everything.

Cloud assistants have a track record of changing the deal after you have bought the box. This one cannot, because the deal is printed on the box. We want this hardware in people's hands now, while it is still ours to buy.

Who it's for

The homesteader, forty minutes past pavement

The satellite link drops most afternoons. The library, the vault and the agent team don't notice.

The smart-home family

Lights, locks, cameras and one Puff watching the network. The kids' favorite feature is the mic-kill switch.

Mom, staying in her own house

Medication reminders in a voice she likes, and a record of her week that no insurer ever sees.

The house two miles from the coast

Runs all day on solar plus battery. When the tower is down, it still knows where the insurance papers are.

Get started

01

Plug it in

Power and network. One shelf, next to the router.

02

It says hello first

No account, no app store, no email address required.

03

It discovers your home

Every device on the network, found and listed for you to approve.

04

You name it, and it introduces itself back.

The demo unit on this page goes by PuffPAI. Yours will not. From then on the memory it builds is about your house, and it stays there.

Puff, the PuffPAI cloud, waving

Those four steps describe HomeBot as a sealed appliance, and that is where this is going. Today both paths ship as software through the beta below: build your own bot with BuildBot's wizard, or install our HomeBot.

Have the hardware? Come break things with us.

The beta covers both paths, as software on one machine you already own. Test BuildBot's setup wizard by building your own bot, or run our HomeBot build and live with it. Tell us which below; you can do both. Two things get you in: hardware that clears the bar, and a GitHub account, since that is how access ships.

You do not need our hardware. You do not need two machines. A Windows laptop with a decent graphics card makes a perfectly good HomeBot.

WHAT IT TAKES ยท ONE MACHINE

memory
The one that decides everything. The model has to fit in RAM, and 32 GB is where we work comfortably. Less still runs: the installer measures your machine and fits the model to it.
graphics
An NVIDIA GPU with 8 GB of VRAM is what we build against. Jetson boards pool memory with the CPU instead, and either shape is fine.
disk
A fast NVMe with room to spare. Models run tens of gigabytes each.
audio
A mic and a speaker, if you want voice.
home
A Home Assistant instance, if you want smart home control.

We have measured two machines: the RTX 2000 Ada laptop we use daily, and the Jetson AGX Orin 64 GB our HomeBot is built on. Neither is a requirement; anything that clears the bar above works. Everything else is untested, so we would rather hear what you have than guess at numbers we have not run.

No payment, no spam, and we never sell the list. That's the whole point. Privacy.

Cypher Sisters

Two sisters building the AI we wanted to live with.

We are not anti-technology. We are pro-people. The question was never whether AI should exist. It is who it serves.

The home build

One machine does the thinking: the appliance in time, your own computer today. Everything else is optional wiring.

THE MACHINE YOU RUN IT ON · brain · memory · vault

The model runs here, the memory lives here, the vault is encrypted here.

MEDIA STORAGE

Your library and camera footage, on drives you can hold.

HOME ASSISTANT

Lights, locks and sensors. Puff talks to it over your own network.
