Profile

Hey HN, I built SafeKey because I was handling patient data as an Army medic, then doing AI research at Cornell. Every time we tried to use LLMs with sensitive data, something leaked. Existing tools only covered text at ~85% accuracy. Nothing worked across modalities. SafeKey is an AI input firewall. It sits between your app and the model, redacting PII before data leaves your environment. What we built:PII Guard: 99%+ accuracy across text, images, audio, video AI Guard: Blocks prompt injection and jailbreaks (95%+ F1, zero false positives) Agent Security: Protects autonomous AI workflows RAG Security: Secures retrieval-augmented generation pipelinesSub-30ms latency. Drop-in SDK for OpenAI,

The company sits in the show hn launch segment, where it competes on its core product or service.
