Overview
Catches emails, phone numbers, SSNs, and API keys before they leave your browser to Claude. One click to redact or send anyway.
It's easy to paste more into Claude than you meant to — a client's email thread, a phone number, an API key sitting in the code you're debugging. Once it's sent, it's sent. ClaudeShield watches every message before it leaves your browser. If it finds something sensitive, it stops the send and shows you exactly what it caught — you choose to redact it or send anyway. HOW IT WORKS Type your message on claude.ai as normal. If ClaudeShield finds nothing sensitive, it stays out of your way completely — no delay, no popup. If it finds something, a quick confirmation appears before the message sends. FREE PLAN — detects and lets you redact: - Email addresses - Phone numbers - Social Security Numbers - Credit card numbers (checksum-verified to cut down false positives) PRO PLAN ($4.99/mo) — adds: - API key and secret detection for major AI, cloud, and dev-tool platforms, plus generic high-entropy secrets - Unlimited redaction history Built for developers, freelancers, and agencies who use Claude for client work and can't afford a copy-paste mistake. 100% local — all detection happens in your browser. ClaudeShield never sends your message content anywhere; it only intercepts the send action already happening on claude.ai.
