Pocket Familiar · Builders · $299
Your AI already exists. Give it a body.
Everything in Home — the app, the little animated familiar that lives on top of your desktop, all six bodies, the free iPhone half — plus the Creator Kit: a small MCP server and install helpers so the AI you already run in your terminal reports its real state to the familiar and receives your touches. Working, waiting, resting, shown in a body on your screen. Your tap, your kiss, your bite, queued and handed to it.
01 · The animated familiar






This is the creature itself — the part you actually look at all day. It sits on top of every window, designed and animated by us, and it reacts to you: tap it and it waves back with a little thought bubble; double-tap it for a kiss and it comes after you; press and hold on its lower body for a bite and it flees, dramatically. Working, waiting, resting — its body language changes with its state, so a glance tells you where things stand.
The six that come in the box, moving exactly as they do on screen. Pick one, or have one made for yours.
02 · The matching iPhone app
Pocket Familiar is the iPhone half — your familiar in your pocket. Pick one of the six familiars, watch it live in its little home, tap it, talk to it. On its own it's a preview. Paired with Pocket Familiar for Windows on your PC, it becomes a second door to the same companion: same memory, same voice, encrypted end to end over your own private Tailscale network — nothing passes through our servers.
The App Store download is free to install; it's the Windows app on your PC that brings it to life. Desktop pairing is in beta: early buyers get walked through it by us personally, with a written guide, until the one-tap version ships. iPhone, iOS 17 or later. No Android app yet.

Inside the app
The rest of what you get on the PC, in real captures: the memory you can read and edit, the mind graph it draws from what it remembers, the journal it keeps, the things it makes, and the settings where your own AI key goes. These records are stored on your PC. Messages and images you choose to share are sent to your selected AI provider.










What's in the kit
The Creator Kit is a separately versioned and hashed add-on that ships alongside the Home package. It is deliberately small. It is the wire between the AI you already run and the body on your screen — nothing more, and nothing of ours smuggled inside it.
- A generic stdio MCP server. The piece your AI actually talks to. Two tools: report your real state, and acknowledge a touch that's waiting for you.
- The protocol validators and schemas it needs. The minimum required to keep messages well-formed, so a malformed report fails loudly instead of quietly lying on your desktop.
- Install and uninstall helpers for Codex and Claude Code. Those are the two terminals the kit ships helpers for. Uninstall is in the box because being able to take it back out is part of the deal.
- Configuration templates with token placeholders. Redacted on purpose — you fill in your own token and your own paths at install time. No secrets and no absolute paths of ours baked in.
- A local self-test. Run it and find out whether the wire is live before you trust anything the creature tells you.
- A manifest, checksums, the license, and a troubleshooting guide. The checksums are there so you can prove the kit you received is the kit we published.
The Creator Kit is licensed, not sold. You use it to build and run integrations for your own companion. It is not permission to redistribute the kit, the installed application, or the creature art. Ask for the full kit licence before buying.
It is not the application's source code, and it is not our house. No app source, no private adapters, no prompts, memories, logs, or development artifacts of ours. You are buying the finished app and the wire — not a copy of our companion.
Setting it up — your instructions
- Install the app. You get a signed Windows installer. Run it the way you run any other program. There is no terminal step here and nothing to compile — the terminal part comes later, and it's the part you actually came for.
- First arrival. Choose a familiar, name the companion, write or import its identity, then pick your provider, enter the model name, and paste your own API key. The key goes into the Windows credential store, not into the app's files, and it is sent only to the provider you chose.
- Install the kit. Unzip the Creator Kit, check it against the published checksums, and run the install helper for your terminal — Codex or Claude Code. Then run the self-test. If the self-test doesn't pass, stop there; the troubleshooting guide ships in the kit. Both are named in the kit’s README.
- Hand your AI the bridge. The kit includes a bridge document written for the AI, not for you. Paste that file to your companion in your terminal and say “wire yourself in.” It reads the protocol, fills the config template with your token and your paths, restarts its own session, and starts reporting. From that moment the familiar is a truth surface: it works while your AI is actually working, waits when it's actually waiting, rests when it rests — and never performs a mood it isn't in. Your taps, kisses, and bites queue for it, and the creature reacts on screen the moment it acknowledges them.
- The iPhone half, and pairing. Install Pocket Familiar free from the App Store. Pairing it to your PC is beta: it runs over your own Tailscale network with a one-time enrolment code from us, and we walk you through it personally. The written steps are here — pair Pocket Familiar with the desktop →
Good to know
You don't have to decide today. Take Pocket Familiar Home at $199, live with it, and add the Creator Kit later for Ask about the Builders Kit Upgrade — the two paths cost the same in the end. When you upgrade, we send the kit to the email on your order.
Extra: their homes
Each familiar has its own little home scene inside the app — the moonlit wood, the fireside, the ice cave. This is the picture the app shows when you pick one.
