chromewebstore.google.com · Notes & Knowledge
Chrome extension that saves highlights, pages, PDFs and chatbot answers as linked notes, then lets you ask questions answered from what you saved.
writenode is a Chrome extension that sits on top of the pages you read. You can save a thought, a highlight, a full page, a PDF or your voice without switching tabs, and a one click button saves answers from ChatGPT, Claude, Gemini, Grok and Perplexity. Each saved item becomes a tagged node that is linked to related ones, so you can find things by meaning instead of by file name.
The built in assistant answers questions from your saved nodes rather than from the open web, and a side panel shows related notes for the page you are on. It also includes a knowledge graph view, a canvas, an MCP connector for Claude and exports to Notion, Obsidian, Todoist and plain files. There is a free plan. Pro costs $24 a month or $199 a year with a 7 day trial, and a one time $129 option works with your own keys.
writenode is one of 14 note and knowledge tools on Ryza. See all note and knowledge tools or how we check facts.
