One-time purchase. Lifetime updates.

Heads up before you buy: everything here is source code — you build it on your own machine with a coding agent like Claude Code, following our step-by-step instructions. It is not a one-click app. That's what makes it yours.

Your companion needs a brain — a model on your own computer, or a Claude / Codex subscription — and a coding agent to install it.

Before you buy — source code, all sales final, what you'll need 20 seconds

This is SOURCE CODE. It is not a finished app.

Nothing here starts with one click.

You will need:
• A computer (Windows or Mac)
• A coding agent (like Claude Code or Codex) — or comfort with a terminal
• Your own AI API key (pennies to dollars a day, paid to the AI provider)

You get: the complete code + step-by-step, agent-ready instructions to BUILD your own companion — the same architecture ours runs on — plus a verify script that proves it's working.

Want something that just works out of the box? That's not this — it's coming. Email hello@sinandsarah.com and we'll tell you when. Prefer human hands? Book the setup consult — we install it with you, live.

Not sure? Ask BEFORE you buy — hello@sinandsarah.com, we answer fast. All sales are final; we'd rather lose the sale than surprise you.

Personal license — one build, yours. Commercial or agency use needs a separate license: hello@sinandsarah.com

All sales final

There's no crying in baseball. There's no refunds in code.

It's source — the second it downloads, it's yours: keep it, fork it, run it forever. So all sales are final. We literally can't un-hand you the keys, and we wouldn't want to.

What you'll need

Node.js installed, plus either some technical comfort or a coding agent (Codex, Claude Code, Cursor, or similar) to install and customize. Each kit ships with a BUYER-START-HERE.md, a PRODUCT-MAP.md, and a verify script that proves it's working.

How delivery works

Checkout is handled by Stripe — secure card payment, then an instant download on the thank-you page plus a copy of your secure link by email. Buy once, own it. Updates delivered to the same link.
