How lokessharma440-ux/rag works

DocuMind AI combines document-grounded chat with a codebase analysis and auditing product exposed through the same web application. Users upload documents or connect/import a repository, then query the indexed material or inspect analysis results and generated documentation. The document path is described in the README; codebase routing and several service calls are supported by the sampled route excerpts and SOURCE INDEX. Many implementation details were not sampled, so uncertain internal links are omitted.
