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!

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…

AI Hotkeys▲78I caught myself copy-pasting into ChatGPT like 50 times a day. Too lazy for that, so I built a shortcut. Select text anywhere on Mac, press a hotkey — text gets rewritten / translated / summarized / whatever, right where you are. No tabs, no copy-paste dance. Native Swift app, hooks into macOS accessibility APIs. Bring your own API key and calls go straight to OpenAI / Anthropic. Or just use the free tier — 20 requests/day, no signup. https://aihotkeys.tech Curious for the feedback

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/proprietary knowledge that would otherwise be too sensitive to process with the ChatGPT API. You can try CapeChat, our…

Hi HN, I’m the founder of Pangea. We’ve built a developer platform where you can easily add security to your code through a simple set of APIs - features like authentication, secrets management, audit logging, redaction of PII, restricting embargoed countries, known threat actor intelligence, etc. With the ChatGPT and LLM explosion, we thought of ways to reduce the risk of both the inputs and outputs from these services. Our NextJS sample app adds a security layer on top of ChatGPT with various security services that you can implement quickly. It’s basically a front end to the OpenAI API…
