writenode is a Chrome browser extension that gives your browser persistent memory by connecting notes, highlights, saved pages, and AI context across sessions. It links newly encountered information to things you have previously saved, helping you avoid re-researching the same topics or reconstructing lost context. writenode surfaces relevant connections over time so you can pick up research or projects exactly where you left off. It is designed for people who juggle many open tabs, scattered notes, or repeated AI conversations that require re-explaining context.
