    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…

    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/

    Hey folks, so I built a chrome extension called [name redacted], an AI assistant that automatically completes your browser tasks for you. You simply enter your task, and [name redacted] uses GPT-4V to figure out the best browser action to perform next repeatedly until the task is accomplished. The idea is that you can delegate your personal tasks like online shopping or making reservations to [name redacted]. You can also use him professionally to find leads on LinkedIn, send status updates to your boss, or research your competitors and write an analysis document. I’m wondering if you would…

    Sharing screen is really scary today with all PIIs and secrets sprawling around your screen, so I built [name-redacted], a small Chrome extension that spots API keys, tokens, emails, and throws a blur overlay on them in real time. The goal is to make screen-sharing feel safe again without adding steps to a demo. Everything runs locally—regex + entropy heuristics compiled to WASM—and the extra CPU cost averages ~1 ms per mutation on my M1. Custom rules can be added with a JSON file for teams that have proprietary token formats. visit [url-redacted] Feedback please <3

    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&#x2F;Bun. Here…

    We’ve built the Cape API so developers can keep sensitive data private while prompting LLMs like GPT-4 and GPT 3.5 Turbo. With Cape, you can easily de-identify sensitive data before sending it to OpenAI. In addition, you can create embeddings from sensitive text and documents and perform vector searches to improve your prompt context all while keeping the data confidential. Developers are using Cape with data like financial statements, legal contracts, and internal&#x2F;proprietary knowledge that would otherwise be too sensitive to process with the ChatGPT API. You can try CapeChat, our…

    Hi HN, I built Redactify, a native macOS app that automatically scrubs sensitive personal and financial data, faces, and metadata from documents and images. The motivation: I frequently use Claude and ChatGPT to analyze invoices and contracts, but I hated the friction of sanitizing them first. I also didn't want to blindly trust the "we don't train on API data" promises of model providers when dealing with actual client data. How it works under the hood: Redactify flattens the document and permanently destroys the underlying text and EXIF metadata. It runs entirely on-device using Apple's…
