PDF Q&A with source citations

This cluster consists of web apps that let users upload PDFs, ask questions, and receive answers with citations to the source page. The dated history before the index start is too thin to read a shape from, with zero dated entries, so the cluster either predates the index or its members are undated. Among traction leaders, ai-document-assistant leads with 2 stars, followed by nanodoc with 1 star and oraculo with 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.
