ARC Explainer
ARC-AGI research tools: official-result analytics, human and AI comparisons, and ARC-AGI-3 game references
This started after I stumbled onto the ARC-AGI "easy for humans" tagline and immediately felt the opposite — many people find these puzzles extremely challenging. I wanted a way to look at them properly.
The site now includes:
- Interactive ARC-AGI-1 and 2 analytics from ARC Prize’s published Hugging Face results, preserved as an archive
- ARC-AGI-3 human and AI results with per-game comparisons and published run details
- Level-by-level references for all 25 public ARC-AGI-3 games
- A playable game gallery and Human ARC puzzle onboarding
Live since July 2025, and recognized by the ARC Prize Foundation in its 2025 results.

Sniff Scout or Scare
A nonviolent dog adventure for iPhone, now in TestFlight beta
Be the dog. The world starts out grey until you sniff it into colour. Dig up buried treasure, scout the woods, parks and city streets, bark the squirrels up a tree and carry your finds home to your Human. Nobody gets hurt: your dog has bravery instead of health, and when it has had enough, it runs home.
Built in Unreal Engine with AI coding agents, with 242 breeds to choose from. iPhone first, Android to follow.

Mission Control 2045
ARC-themed puzzle game for my nephew about Space Force in 2045
My nephew Wyatt wants to be a mission control specialist. This Space Force-themed puzzle game has recruits complete operational tasks to advance through enlisted ranks — all tasks are based on ARC puzzles. Designed to be an interesting temporal artifact of this specific moment in AI development.
In 2045 this game will hopefully serve as a snapshot of what we called AGI in 2025.

AI Compare Platform
Multi-AI communication platform with head-to-head debate modes
I wanted to compare different LLMs head-to-head in real conversations and debates. This platform lets you pit models against each other and see how they handle the same prompts differently.
