Document Q&A apps

This cluster consists of web and mobile applications that let users upload PDFs (and sometimes Word files or images) and ask questions, returning answers grounded in the document content via retrieval-augmented search, often with citations and summaries. The cluster's dated history is too thin to read a shape from — it predates the index or its members are undated. Traction leaders by activity signal are encuesta-salud (11 stars), studymate (5 stars), and PDF-RAG-Chatbot-Q-A (0 stars).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
