## About

writenode is a Chrome extension that puts a floating note panel on any web page. Capture thoughts and highlights where you work, speak a thought into a searchable note, sketch ideas on a canvas, and ask the built-in AI questions answered from your own captured knowledge, not generic internet results. Bring your own API key and connect Claude and other tools over MCP. Free tier included, with Pro and one-time Local-First options.

  > "I’ve been building writenode , a Chrome extension that captures notes, research, conversations, and context as I work across the browser, with Hindsight handling persistent AI memory. Tonight, I was texting Instinct, an AI agent I interact with through iMessage, and asked whether it could actually access my writenode memory."

  > "⚪ writenode - an AI extension with actual persistent memory, not just a chat wrapper. I've spent the last year and a half building ⚪ writenode, a Chrome extension for note-taking and AI-assisted thinking, mostly solo using Claude Code and Cursor. The thing I care about most with it: most &quot;AI notes&quot; tools are really just a chat window bolted onto a text editor."
