Vein

Quick and efficient knowledge structuring capture tool

Vein is a locally-first browser knowledge capture layer. Vein was born from a very specific problem. Many high-frequency information workers don't lack knowledge tools. What they lack is a more convenient way to save. Today's web-saving methods typically have two problems: Either they're too light — leaving behind a link that will never be opened again. Or they're too heavy — requiring you to enter another system for full organization. Vein aims to occupy the middle ground. It is not your second brain, nor a new reading container. It is a knowledge intake layer within the browser. When you come across something worth keeping on a webpage, Vein lets you do it on the current page: - Capture a fragment - Edit and modify - Preserve the source - Apply minimal structure The point isn't to be "cooler," but to better fit real workflows. You don't need to organize the moment you capture — just securely hold onto the information first. Later, it can flow into Obsidian, Notion, or any system of your own. Vein's goal is not to replace all tools. It is to become the default entry point you use without thinking.
