Epitree: Save Words, Build Concept Trees

Save any word with its definition, context, and source link. Turn any article into a connected concept tree.

Most of what you read online is gone within a week. Epitree catches it while you browse and files it into a growing tree of connected concepts. SAVE FROM ANYWHERE Highlight any word or phrase and click Save, or right click a selection and choose "Save to Epitree". Every entry keeps a definition, a context sentence, and a link back to the page you found it on, so months later you still know where the idea came from. TURN A PAGE INTO A LEARNING TREE Import Page reads the article you're on and builds a structured tree of 30-50 concepts from it, adapting to the kind of page it is: • Job posting → required and preferred skills, interview topics, what to study • Research article → core concepts, methodology, findings, related theories • Tutorial or docs → key concepts, APIs, patterns, best practices, gotchas • News and analysis → key entities, events, background context • Comparison or review → the items compared, the criteria, the trade offs SEE HOW IDEAS CONNECT Saved terms don't sit in a flat list. The side panel shows your library alongside the semantic connections between concepts, so related ideas reinforce each other rather than compete for memory. REVIEW ON THE WEB Study sessions and your full concept tree live on the Epitree web app, a click away from the extension. The popup shows your library size and retention rate at a glance.
