I built an open-source AI text detector that ranks #14 on the RAID benchmark and #1 among CPU-only solutions. No GPU required.

Why this matters

Big Tech is approaching AI detection all wrong. They're throwing massive compute at the problem – training billion-parameter models that require expensive GPUs just to detect whether a text was written by AI.

This is fundamentally misguided. Using brute-force compute to fight brute-force compute is a losing game. It's an arms race that only the largest companies can afford, and it's not scalable.

The CPU-first philosophy

I believe the solution isn't MORE compute – it's SMARTER compute. This detector uses only 60 handcrafted statistical features and a lightweight XGBoost model.…
