CLUSTER SEARCH-POWERED-CONTENT · 46 ENTRIES · EARLIEST ENTRY 2025-01-07

AI search and answer engines

The cluster consists of AI-powered search engines, answer engines, and knowledge bases that use retrieval-augmented generation and semantic search to answer queries with citations. Pre-index dated history is thin and irregular: a single entry in 2009-12, then sporadic entries from 2025-01 through 2026-06 with counts of 1, 1, 2, 2, 2, and 1, showing no consistent growth pattern. Traction leaders are DeepSearch (8 stars), RAG-Document-Agent (3 stars), and smart-fetch-style (2 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.
