Pseudonymize personal data before pasting into AI cats

Alright so if you run a self-hosted blog, you've probably noticed AI companies scraping it for training data. And not just a little (RIP to your server bill). There isn't much you can do about it without cloudflare. These companies ignore robots.txt, and you're competing with teams with more resources than you. It's you vs the MJs of programming, you're not going to win. But there is a solution. Now I'm not going to say it's a great solution...but a solution is a solution. If your website contains content that will trigger their scraper's safeguards, it will get dropped from their data…

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…

Hello HN, I’m Kamil. The past months have been filled with news about ChatGPT, Bard, etc. Thankfully, there are some heroic attempts to bring that power to the users. I wanted to contribute to that effort with my side project, an extension for Chrome: it makes searching the history by meaning – instead of the exact words – possible. This is only a proof of concept, building on the excellent transformers.js[0], and running entirely in the browser. My goal here is to explore the possibilities unlocked by a client-side AI. I would love to have your feedback, to know which direction that project…

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…

I've been researching the bot & proxies space for years. I slowly incubated a service to protect public forms, contents and APIs. It recenty reached a few million daily requests and I now dare to bring it to light. Truesign detects bots, proxies/vpns and fake emails, through a single request from the browser, without challenges or user interaction. It can block the request based on rules you choose, or grant a token with encrypted information about the visitor for you to decide. I created a few pages to showcase how it works: - https:/demo.truesign.ai/protected-form : a form…

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/

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,…
