What it does
Most AI tools help you talk to AI more. OmniShield helps you stop leaking to AI. ChatGPT extensions organize chats or add sidebars. We mask secrets at send time — inside ChatGPT, Claude, Gemini & Cursor — before they leave your browser. On-device. No prompt upload. API keys,env dumps, JWTs, emails: gone before send. Free core masking. Pro adds OCR, healthcare patterns, block mode. Other launches give you a better assistant. We give you a seatbelt for AI.
OmniShield masks API keys, passwords, and PII before they reach ChatGPT, Claude, Gemini, Perplexity, and Cursor — 100% on-device. Free Chrome extension.
OmniShield intercepts your prompts before they leave the browser, replacing API keys, passwords, and PII with safe placeholders — on your device, zero servers. Developers, founders, and security teams who use LLMs daily without leaking credentials or customer data. Hooks the send path so the raw secret never reaches the AI provider's servers — not just a visual blur or warning. Free and Pro process prompts locally. Your chat content never touches OmniShield's infrastructure. Masking runs in microseconds at the browser level — no round trip, no perceptible delay. OpenAI, AWS, GitHub, Stripe, GCP keys + emails, cards, phone numbers, and custom rules (Pro). Healthcare pattern pack detects PHI…from omnishield.app

Clipto MCP▲655Hey HN, We recently built Clipto. It’s a tool that lets you search over terabytes of video, audio, and images on your computer, without relying on the cloud. Motivation: we probably all had this similar experience, we know a moment exists in a video or audio, but finding it takes hours scrubbing the timeline. You can send all the media to process in the cloud, but it’s slow, expensive and raises privacy concerns. So we decided to build our own on-device media search engine. How it works (high level): 1. We ingest video, audio, image; normalize formats via ffmpeg; run content analysis to…

Hello HN! I found that picking out plausible but diverse skin tones for my digital art and game development projects was kind of difficult, and I got curious about if there was a way to define a color space that made it easy. I've built a color picker and procedural generation algorithm based on the space as well as a bunch of other fun js features and demos throughout the page that use the equations. If you find it interesting, I have lots of explanations of how I built it and what properties the space has. The methodology might be a bit shaky, but hopefully the result is as helpful for…
