DocuMind AI: Multi-Source Hybrid Retrieval.

DocuMind AI is an intelligent technical documentation research platform designed to help developers, students, and technical researchers find reliable answers without manually searching through extensive documentation websites. Traditional documentation research often requires users to navigate multiple pages, follow links, compare API references, and search for relevant code examples. This process can become time-consuming, particularly when working with unfamiliar frameworks, libraries, and technologies. DocuMind AI addresses this challenge through a combination of live web crawling, Retrieval-Augmented Generation (RAG), semantic vector search, and PostgreSQL full-text search. Users can provide a documentation URL, specify a research objective, and optionally identify a target version. The system discovers relevant pages within permitted website boundaries, extracts and processes their content, and builds a temporary searchable index for the research session. Using hybrid retrieval, DocuMind AI combines semantic similarity search with keyword-based retrieval to identify documentation passages relevant to a user's question. These passages provide context for generating answers grounded in the retrieved technical information.
