Editorial interest 78/100 Selection signal · not a rating of the site

A Claude Code plugin and Chrome extension that the site says replace detected personal data with placeholders before prompts reach Claude or ChatGPT, then restore values locally.

Landing page captured for the 2026-09-28 issue.

For: Claude Code, Claude.ai, and ChatGPT users handling sensitive data
Worth noticing: The page says card numbers pass Luhn checks, IBANs use mod 97, and timestamps and private IPs are left alone.

Field notes

The page documents separate setup paths: a Claude Code marketplace plugin requiring Node.js 18 or newer, and an unpacked Chrome extension requiring Chrome 111 or newer. Its examples show checksum checks for card numbers, IBANs, and Turkish national IDs, while timestamps, private IPs, and package names are left untouched; the page says the browser placeholder map disappears when the tab closes.
