AI document Q&A assistants

This cluster consists of AI document assistants that let users upload files (often PDFs) and ask natural-language questions, with answers grounded via retrieval and source references. Entries before the index start were sparse and irregular, appearing in seven different months from January 2025 to July 2026, with July 2026 having two entries. ollmo leads traction with 17 stars, followed by smart-city-gigahack2026 and ai-knowledge-workflow-assistant at 2 stars each.

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.
