AI Second Brain, Meet Claude: The Setup I Use Every Week

TL;DR

  • Cluing is an AI second brain app that saves, organizes, and utilizes information.
  • New features include MCP integration for direct connection with AI tools (Claude, ChatGPT, Gemini), AI organization through chat, document import into AI chat, a visual knowledge graph, and X (Twitter) mobile integration.
  • The app offers three core functions: saving anything from anywhere (web pages, posts, videos, newsletters, notes), letting AI organize knowledge using structures like PARA, and using saved knowledge within AI tools like Claude, ChatGPT, and Gemini without tab-switching.
  • Five weekly workflows are presented: turning testimonials into landing page copy, researching new topics over time by collecting resources, extracting key ideas from PDFs, creating a ranked shortlist from saved ideas, and getting weekly recaps of saved content.
  • Setup involves creating an account, installing browser extensions (desktop) or using the mobile app/mobile extensions (mobile), and forwarding newsletters to a unique Cluing email address.
  • Cluing's value lies in its ability to maintain context from years of reading and notes, making saved information usable and providing AI tools with relevant context.
