01 / A familiar chat. A new adventure.

What does it mean to play inside AI?

RELAY makes story games where you learn to work with AI by creating something of your own.

Talk to your guide in everyday language. They introduce the world, set challenges, and help you move forward. You suggest ideas, see what happens, and refine the details.

It starts with curiosity. You don’t need ready-made prompts or coding skills.

Sample conversation
Master of Forms

Imagine a companion you’d want to take with you. What do they look like? What’s their personality?

You

A tiny dragon made of clouds. Curious, but a little sleepy.

Master of Forms

Let’s start with your idea. What would make it special—see-through wings, or a tail like a thundercloud?

Your idea sets the direction

02 / Three missions to a pet of your own

Come out of curiosity. Leave with your own character.

RELAY Day is a free first step into a bigger story. A short adventure to try the format and get a feel for AI.

From idea to companionRELAY / Balloon Dog
The lamp dog that became a digital pet

Balloon Dog is an example from a playthrough. In RELAY Day, you’ll create a character of your own.

03 / Something you get to keep

Who will you dream up?

A cloud dragon. An astronaut cat. A robot with your friend’s personality.

A pet is a digital companion you can enable in ChatGPT and Codex. You choose the idea, appearance, and personality. AI helps bring them to life.

The Balloon Dog example started with a real lamp dog. Your character can start with anything.

Your idea.Your personality.Your pet, too.

04 / How to play

Your way into the game

Start with three simple steps.

The ChatGPT/Codex desktop app, a ChatGPT/Codex subscription, and about 30 minutes to spare.

The game is free. Your AI access and limits depend on your plan. Image generation isn’t available on Free. OpenAI plan details ↗

02

Put the README in a folder

Download the game’s starter file and save it in a new folder called RELAY DAY. Add that folder as a project in the app.

03

Meet your guide

Open a new chat in the project and say hello. Then reply in your own words.

Before your first step

Things you might want to ask.

Still have a question? Ask the RELAY team ↗

I’ve never used AI. Can I play?

RELAY Day introduces the format from the very first step. Talk to your guide in everyday language, suggest ideas, and follow the challenges. You don’t need to code or learn prompts beforehand.

Is it really free?

RELAY Day itself is free. Creating your pet requires a ChatGPT/Codex subscription. Features and limits depend on your account and plan; image generation isn’t available on Free.

See OpenAI plan details ↗
Can I play on my phone or in a browser?

These RELAY Day instructions use the ChatGPT/Codex desktop app with access to a project folder. You can browse this page on your phone and come back to play on your computer.

How long does it take?

Allow 30–45 minutes. AI may spend about 15–30 minutes of that time creating your pet. The timing depends on your idea and the service. While it works, explore the AI tips in the Handbook you receive during RELAY Day.

What kind of pet can I make?

You invent the character: an animal, a fantasy creature, or an object brought to life. Choose something that interests you. Your guide helps you describe the idea and create a pet for ChatGPT and Codex. Balloon Dog is one RELAY example, rather than a ready-made character for every player.

What if I get stuck?

Type “Поднять Маяк” (“Raise the Beacon”) in the game chat. If you need help starting the game or using the app, email support@relay-project.com.

What happens after RELAY Day?

You keep the pet you created and your first taste of RELAY. Day introduces the main story. If you’d like to continue and build more ambitious projects with AI, move on to The First Signal.
