PiiBlocker
Chrome extension that masks sensitive data before it reaches AI chatbots
Visit piiblock.com ↗What is PiiBlocker?
PiiBlocker is a free Chrome extension that detects and masks personally identifiable information before it's sent to AI chatbots like ChatGPT, Claude, and Gemini. The tool identifies 15+ types of PII—including names, email addresses, and API keys—replacing them with placeholders like [PERSON_A] before submission, then restores the original text in the AI's response. All processing happens locally in your browser with no server involvement or data collection.
Designed for workers and teams concerned about accidentally sharing confidential information with AI services, PiiBlocker offers a free tier with core detection, plus Pro and Enterprise plans with advanced features like automatic soft-PII masking and admin dashboards. The maker built it using Claude Code.
