OP 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…

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…

Needed this in my own work, anonymizing PII/PHI and decided to build this because presidio didn't really cut it for our use-case. Try it and maybe let me know if you have any feedback :)

I 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/

I made FingerprinterJS, a small library with no dependencies that creates browser fingerprints from signals like canvas, WebGL, audio, fonts, userAgent, and screen info. It’s written in TypeScript, lets you enable/disable collectors, add custom data, and includes a simple suspicious-activity score. Would love feedback.

I 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!

Hi HN, I'm Andrios, founder of hoop.dev (YC W21), we build runtime controls for agents. We just released Alcatraz. We built it because our product is written in Go and we do real time Data Masking, but we were using MS Presidio (Python) for PII detection and it made connections slow. There was a good discussion here a few months ago when OpenAI released their Privacy Filter: (https://news.ycombinator.com/item?id=47870901). A lot of questions were built into our design. Structured identifiers (credit cards, SSNs, etc) are deterministic and you can verify them with checksum.…

PII Detective is a web application designed to identify, classify, and protect Personally Identifiable Information (PII) in data platforms such as BigQuery and Snowflake. It leverages LLMs to identify PII column names, and with human-in-the-loop validation, uses Dynamic Data Masking Policies to easily enforce Access Control Limits (ACLs) while minimizing user friction. For comparison, GCP has a "Sensitive Data Protection" service which promises similar functionality, but it can become extremely costly since it runs hundreds of regex queries on the entire contents of the table. For…

What PII-Shield does: It's a K8s sidecar (or CLI tool) that pipes application logs, detects secrets using Shannon entropy (catching unknown keys like "sk-live-..." without predefined patterns), and redacts them deterministically using HMAC. Why deterministic? So that "pass123" always hashes to the same "[HIDDEN:a1b2c]", allowing QA/Devs to correlate errors without seeing the raw data. Key features: 1. JSON Integrity: It parses JSON, sanitizes values, and rebuilds it. It guarantees valid JSON output for your SIEM (ELK/Datadog). 2. Entropy Detection: Uses context-aware entropy…

Hello Hacker News! I’m Tomasz, creator of Privacy Thing, a browser extension for Firefox and Chromium-based browsers. I’ve just released its Preview version. Privacy Thing aims to reduce browser fingerprinting—the tracking of users without cookies. It began as an internal project: a simple location simulator. Over time, I expanded it to cover more fingerprinting surfaces. It now has 13 protection categories affecting 50+ browser APIs and methods: Geolocation, time and locale settings, Canvas, WebGL, Audio, Navigator, Screen, Client Hints, Battery, WebRTC, Dedicated Workers, Service Workers,…

Hi HN, I'm the creator of LogLens. Like many of you, I spend a lot of time digging through massive structured (mostly JSON) log files. I've always relied on grep for its speed and then piped to jq for the actual filtering, but I find this workflow gets slow and complicated, especially with multi-GB files or complex queries. LogLens is my attempt to fix this. It's a single, fast CLI tool written in Rust that's designed specifically for structured logs. It combines a simple SQL-like query language (e.g., loglens query './logs' 'level == "error" && status >= 500') with parallel,…
