What it does
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!
Free PII redaction API for developers. Replace emails, names, phones with reversible placeholders before sending to ChatGPT. 500 requests free. Data masking for GDPR compliance.
Replace emails, names, phones with reversible placeholders before sending to ChatGPT/LLMs. Restore the original values after getting the AI response. 5-minute setup. 500 requests free. No credit card. # Redact PII before sending to LLM curl -X POST https://api.scrubprompt.com/api/redact \ -H "Content-Type: application/json" \ -H "X-API-Key: your-api-key" \ -d '{"text": "John lives at [email protected]"}' # Response: {"text": "[[SP_P_abc123]] lives at [[SP_E_xyz789]]"} # Restore after LLM response curl -X POST https://api.scrubprompt.com/api/restore \ -H "Content-Type: application/json" \ -H "X-API-Key: your-api-key" \ -d '{"text": "Hello [[SP_P_abc123]]"}' # Response: {"text": "Hello John"}…from scrubprompt.com

Hi HN, I’m one of the maintainers of Bridge Anonymization. We built this because the existing solutions for translating sensitive user content are insufficient for many of our privacy-concious clients (Governments, Banks, Healthcare, etc.). We couldn't send PII to third-party APIs, but standard redaction destroyed the translation quality. If you scrub "John" to "[PERSON]", the translation engine loses gender context (often defaulting to masculine), which breaks grammatical agreement in languages like French or German. So we built a reversible, local-first pipeline for Node.js/Bun. Here…

Local Privacy Firewall-blocks PII and secrets before ChatGPT sees themDec 2025 · github.com · ▲111OP here. I built this because I recently caught myself almost pasting a block of logs containing AWS keys into Claude. The Problem: I need the reasoning capabilities of cloud models (GPT/Claude/Gemini), but I can't trust myself not to accidentally leak PII or secrets. The Solution: A Chrome extension that acts as a local middleware. It intercepts the prompt and runs a local BERT model (via a Python FastAPI backend) to scrub names, emails, and keys before the request leaves the browser. A few notes up front (to set expectations clearly): Everything runs 100% locally. Regex detection…

NICH: GPT Anonymizer2025 · nichtech.uk · ▲14I built NICH after realising I couldn't use ChatGPT for my conflict research work without risking data leaks. It's a browser extension that: - Anonymises names, emails, and addresses in one click - Preserves context for AI to understand - Restores original data in AI responses - 100% browser-based (no cloud, data never leaves your device) Built it for researchers, lawyers, HR professionals or simply anyone handling confidential data who wants AI assistance without compliance nightmares. Free to use: https://www.nichtech.uk Would love feedback from the HN community!

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
