Built this because I was tired of manually redacting PII before sending user data to ChatGPT. What it does: • Replace "John" → [[SP_P_xxx]] before sending to any LLM • Restore original values after getting the response • Supports 20+ PII types (names, emails, phones, credit cards, SSN, etc.) Simple API - integrate in 3 lines of code. Free tier: 500 requests/month Try it (no signup needed): scrubprompt.com/playground Questions? I'm the founder - ask me anything!

What inspired me to build this? I was working on an AI project that needed to process user data for training. But manually redacting PII (emails, phones, names, etc.) was incredibly tedious and error-prone. I kept thinking: "There has to be a better way." The problem I tried to solve: - Developers waste hours manually hiding sensitive data - Regex is fragile and misses many cases - Existing solutions are expensive or enterprise-only How it evolved: 1. Started with simple regex-based detection 2. Realized regex wasn't enough 3. Added reversible placeholders so data can be restored 4. Built simple REST API for easy integration Why free tier? I believe every developer should be able to secure their data without paying. The free tier (100 requests/month) is enough for testing and small projects. Would love your feedback!
