CopyCat

What it does

Every time you copy text, some websites silently register clipboard event listeners to read what you copied — without asking. Medium does it. News sites do it. You'd never know. CopyCat is a Chrome extension that catches them in the act. It shows you exactly which sites are monitoring your clipboard, blocks them from reading it, and optionally watermarks your copied text so you can detect if it ends up in an AI.

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
