CLUSTER BEFORE-BROWSER-EXTENSION · 10 ENTRIES · EARLIEST ENTRY 2026-01-18

AI privacy masking extensions

This cluster consists of browser extensions that automatically detect and mask sensitive data—such as API keys, tokens, and personal identifiers—before it is shared with AI chatbots or tools. The cluster's dated history is too thin to read a shape from, with only four dated entries predating the index start. On traction, Secureintent-Extension leads with 8 stars, followed by fab-mask with 3 and hide-and-sneak with 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.
