Obelisk Systems is a small team from Salzgitter, Germany. We build the tools we were missing ourselves and design game UI for other developers.
We write the code (Unreal C++, TypeScript, Python) and design the interfaces ourselves, so what you see is what we can actually build.

What do you offer?
Tools for game developers and game UI design. Nodio plans your game as a connected graph, the Engine Mentor is an AI tutor inside your engine, and more tools follow soon. We also design game UI for your game, booked via Fiverr.
Is there a subscription?
Not with us. Our tools are free or a one-time purchase, design work has fixed packages from $20. If a tool uses AI, your AI provider bills that, under your plan or per use.
Where does my data go?
Our tools work locally: no accounts with us, no telemetry, your projects stay on your machine. Where AI is involved, data goes straight to the provider you choose, with no server of ours in between. This website sets no cookies and loads nothing from third parties.
