About the studio
Rusty & Ruffy International Studio.
An independent AI product studio from Switzerland, founded by Rusty and Ruffy. We build focused AI products for problems we know from our own work.
Our story
We saw the problem in our own work.
We started as two developers who wanted to build Roblox games – and quickly learned that modern game development relies heavily on AI. But general-purpose models aren't made for Roblox: they mix up Luau with plain Lua, suggest APIs that don't exist and forget everything about a project between sessions.
So we started building what we were missing: one AI for the whole game – from the plan to 3D models, scripts, UI and graphics – with its own memory that learns from experience. That became our first project, Brickbrain. The same approach drives everything we do – next up is RR Lingua.
Mission
Specialized AI that gives small teams real leverage.
Real work needs tools that understand the specific field and remember the context. We build exactly those tools – privacy-conscious, and proven in our own work before anyone else gets them.
