DeepWiki, a free tool from Cognition AI (makers of Devin), automatically generates Wikipedia-style documentation for GitHub repositories. By replacing 'github.com' with 'deepwiki.com' in any repo URL, developers get a project summary, module-level explanations, architecture diagrams, and a conversational Q&A interface powered by RAG. It analyzes source code, config files, and READMEs to produce grounded, context-aware answers rather than hallucinated responses. Public repos are free; private repos require a paid plan. Over 50,000 top GitHub repos are already indexed.
