AI prompt data redaction tools
The cluster comprises privacy tools that detect and redact sensitive data—like API keys, tokens, passwords, and personal identifiers—on-device before it reaches AI models or other untrusted destinations, often as browser extensions or desktop utilities. The dated history is too thin to read a shape from, as only 4 dated entries exist, none before the index start, with additional members undated. Traction leaders are openmasq, shim-guard, and Secureintent-Extension, each with 6 activity stars.
Entry timeline
ENTRY TIMELINE
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.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 3 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
