Fanout

Fan-Out analyzes web pages to figure out which user queries your content actually answers and which ones it misses. It scrapes a URL, then generates 15-25 query variations using Google's patented fan-out methodology (equivalent phrasings, specs, comparisons, follow-ups, clarifications). For each variant, it uses Self-RAG to check if your content covers it and pulls exact quotes as evidence. You get a coverage score, gap-by-gap recommendations, and a visual dashboard. The hybrid mode is the sweet spot: point it at your article with a target keyword and it shows you exactly what's missing for GEO and AI search citation. Built on Anthropic's API, runs via stdio, outputs interactive markdown reports.
