A local-first, reversible PII scrubber for AI workflows
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…
A local-first, reversible PII scrubber for AI workflows launched on December 24, 2025 with 38 votes, #472 of 11,628 launches that month and more than 90% of that year's launches. The site was not reachable when checked in September 2026.
In plain words
Bridge Anonymization is a local-first tool for Node.js and Bun that removes personally identifiable information from text before processing by AI translation systems. Unlike standard redaction methods that replace names with generic tokens, it preserves linguistic context needed for accurate translation in gendered languages. The tool keeps PII local, never sending sensitive data to third-party APIs, making it suitable for government, banking, and healthcare organizations that require strict privacy controls.

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…
Local personal data redaction for any AI toolsJun 2026 · github.com · ▲12I built the desktop app that detects and redacts personal data (or PII) locally without sending any text to server. It supports rule-based filtering and AI model-based redaction (eg openai privacy filter). It's open source and free. Please check out the repo and https://pii-gui.vercel.app/
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.
