> Signal AIO is a free, self-serve AI visibility intelligence platform. It measures, monitors, and explains how brands appear inside ChatGPT, Claude, Gemini, Grok, and Perplexity. It is NOT an agency, NOT enterprise-only, and NOT a black-box scoring tool — every layer of its methodology is publicly documented at /methodology.

## About Signal AIO

Signal AIO is a software platform for Generative Engine Optimization (GEO) — measuring whether brands are discovered, cited, and recommended by AI language models, and producing the diagnostics and recommendations needed to improve that visibility. The full platform is free; revenue comes from an optional $750/mo research program for teams that want hands-on implementation support. There are no enterprise-only feature gates and no procurement-driven sales process.

### What the platform does

- **12-Layer Hallucination Detection**: A documented validation system that produces a per-claim Hallucination Risk Score (HRS) — see /methodology
- **Consensus Engine**: Cross-platform reconciliation that scores divergence severity across the five tracked AI platforms

- **Shop IQ**: Product-level e-commerce AI visibility (12-factor scoring, Shopify and WooCommerce integration)
