MaskedPII is the AI data leak prevention tool your compliance team has been waiting for.
As employees use ChatGPT, Claude, and Gemini for daily work, sensitive data — Social Security numbers, credit cards, dates of birth, API keys, internal project names — is leaking to public AI models every day. Most companies have zero visibility into it.
MaskedPII fixes that. It runs silently in your browser and intercepts sensitive data before you hit Send.
What it detects: ✓ Social Security Numbers ✓ Dates of Birth ✓ Credit Card Numbers ✓ Phone Numbers & Email Addresses ✓ API Keys & Secret Tokens ✓ IP Addresses ✓ Custom keywords & internal codenames you define
Key features: ✓ Real-time block modal — stops the message before it sends ✓ Custom secrets — add any word or phrase to block ✓ Full audit log — every blocked attempt timestamped and stored locally ✓ CSV export for compliance reporting ✓ On/Off toggle — disable instantly when needed ✓ Works on ChatGPT, Claude.ai, and Google Gemini ✓ 100% local processing — no data ever leaves your device
Built for teams operating under GDPR, HIPAA, SOC 2, and the EU AI Act.
