ARC-AGI Explainer

A personal research platform for ARC-AGI — built by a veteran game producer who isn’t trying to solve the benchmark, just trying to understand it and make it easier for the people who are.

Background

I’m a video game producer, not an engineer. I work with engineers. I’m not going to solve ARC-AGI — I just find it fascinating and wanted to build something that might be useful to the people who are actually working on it. Started in July 2025 as a curiosity project, grown into a full research suite. In late 2025, ARC Prize recognized the effort — that meant a lot. The platform is live and actively maintained.
