CLUSTER BROWSER-EXTENSION-EMAIL · 11 ENTRIES · EARLIEST ENTRY 2026-08-18

AI email productivity tools

The cluster comprises browser extensions and AI tools that assist with email tasks such as composing replies, generating responses, dictation, classification, and productivity features for Gmail and Outlook. The cluster's dated history is too thin to read a shape from, with only 4 dated entries before the index start, predating the index or with undated members. Traction leaders are tone-twist-ai-19, ai-email-reply-generator, and Smart_Labeler, each 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.
