AI browser page assistants

This cluster consists of browser extensions that embed an AI assistant to interpret the current page—answering questions, summarizing, explaining, rewriting, or turning content into a searchable knowledge base. The cluster's dated history is too thin to read a shape from—only one dated entry exists before the index start, and two members have no source date. On traction, SideAsk leads with 49 stars, followed by arex-reader (3) and Archiver (1).

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.
