Robin, an AI-powered dark-web OSINT tool shown at DEF CON 33 by Apurv Singh Gautam, consolidates search, filtering, scraping and LLM analysis into one pipeline. It queries 15 onion search engines, narrows ~100–200 results to the top 20 using an index-aware LLM filter, scrapes those sites, then uses a final LLM prompt to extract artifacts (crypto addresses, PII, actor aliases) and produce investigator-formatted Markdown reports in ~30–45 seconds.
