AI email management assistants

This cluster comprises AI-powered email assistants that summarize threads, draft replies, prioritize messages, and extract action items or deadlines. Dated entries are sparse from 2013 through early 2025, then become more frequent from February 2025 onward, with the largest monthly counts in April and June 2026. Traction leaders include heyflare, which ranks highest in activity signal, and taskuary, which holds the highest star count at 45.

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.
