Profile

Hey HN,We just shipped PII detection for CyberCage.The idea: builders move fast, copy-paste doesn't think. Sometimes sensitive stuff ends up in AI tools — SSNs, API keys, customer data. Not intentional, just momentum.So we built something that catches it before it leaves the machine.What it does:- Detects SSNs, credit cards, phone numbers- Catches API keys (AWS, GitHub, OpenAI...)- Custom patterns you define- Works on images too — all processed locallyML powered detection runs on-device. Nothing gets sent anywhere for scanning.You choose what happens: log, block, or auto-redact.Works with Claude Web, ChatGPT, GitHub Copilot, x.AI.See it in action: https://www.youtube.com/watch?v=FiibtTUSqU8W
