CitableHub is the free AI-readable directory that structures software projects so AI assistants like ChatGPT, Perplexity, Claude, and Gemini can discover, verify, and recommend them. Traditional landing pages are built for humans, so AI crawlers cannot reliably extract what a product actually does. CitableHub fixes this by turning each project into a clean, machine-readable entity profile with structured features, tech stack, use cases, and verifiable proof, plus schema and an llms.txt feed built for Generative Engine Optimization (GEO). The result: your product becomes citable, gets recommended in AI answers, and earns qualified traffic from the tools people now ask instead of Google.
