Brickbrain – new game
I want to make a horror game where a monster chases you.
Love it! A few questions first:
  • Where does it take place – a school, a forest, a hospital?
  • Solo or with friends?
  • How long should one round last?
… and a few more.

Brickbrain

One AI for the whole game.

How we work

Four rules we don't break.

Problem first

Every project starts with a real problem we ran into ourselves – not with a technology looking for a use case.

Build it ourselves

We use our own products every day before anyone else does. If it doesn't help us, it won't help you.

Privacy by design

Swiss values: your data stays under your control. Local-first wherever possible, transparent everywhere else.

Stay focused

A small team with clear priorities. We bring one project to maturity before we scale the next.

What does RR stand for?

Rusty&Ruffy

from Switzerland to the world

Two founders. One studio.

We started with a simple observation: today's AI tools are powerful, but rarely made for the work we actually do.

So we build our own. Clear problem, focused product, AI that is made for exactly that job – and proven in our own work first.

Our story

Frequently asked questions

What is RR International Studio?

An independent AI product studio from Switzerland, founded by Rafael Ethan Kuhn and Lucas Canales. We build focused AI tools – starting with Brickbrain, an AI that builds complete Roblox games.

Is it a registered company?

Not yet. We are an early-stage startup project and not entered in the commercial register. We plan to incorporate once our first product is ready.

Why do you need cloud credits?

Training and evaluating a specialized model needs GPU compute. Credits let us train Brickbrain's model and test it on real Roblox projects without outside funding.

Can I use Brickbrain?

Not yet. A first internal prototype is running, and we use it for our own games. A closed beta for other Roblox developers is planned once it has proven itself.

Are you affiliated with Roblox?

No. We are independent developers building for the Roblox platform. Roblox is a registered trademark of Roblox Corporation.
