Epitree by Epitree

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.
