# Cluing Cluing is a knowledge capture and organization platform by Collabwriting Inc. The pitch: save content with one click from anywhere (YouTube, Reddit, PDFs, LinkedIn, X, Kindle, ...), let AI organize the snippets into topics and clusters automatically, then use that curated knowledge base as context for frontier AI models. Their top tier includes unmetered [[Model Context Protocol (MCP)]] requests, which says a lot about where this category is going: your captured knowledge as a first-class data source for AI assistants. Freemium model: a free Hobbyist tier with unlimited snippets, a Professional tier at $12/month, and a $120/month Superhuman tier. Team collaboration, shared clusters, and PDF collaboration round out the feature set. Around 18k users as of mid-2026. Worth watching from a [[Personal Knowledge Management (PKM)]] angle. It competes with [[Readwise]] on the capture side, and the "AI organizes everything for you" promise targets exactly the audience that finds manual organization overwhelming. My skepticism is the usual one: capture is the easy part; tools that organize FOR you tend to produce archives nobody revisits. ## References - Website: https://www.cluing.io/ ## Related - [[Personal Knowledge Management (PKM)]] - [[Readwise]] - [[Model Context Protocol (MCP)]] - [[Gray Box]]
