AISEO-Audit is an open-source tool that analyzes any URL and scores how well its content can be fetched, understood, and reused by generative AI engines like ChatGPT, Claude, Gemini, and Perplexity. It measures AI Readiness or GEO signals across 30+ research-backed factors, giving fast, deterministic audit scores you can use locally, in CI/CD, or for optimization insights. Code and CLI are on GitHub.
