Product — Structure
A structure shaped by your judgement
Annotate passages, leave notes in the margin, and draw links between related sections across different sources. What accumulates is a map of your own connections and judgement — not a flat document dump or a generic folder tree.

What you can do
Annotations
Highlight and annotate specific passages — the marks live on the source itself.
Margin notes
Leave notes anchored where the thought happened; jot longer ideas as they come.
Links across sources
Draw connections between related sections in different documents, and follow them later in either direction.
Citations
Pin a claim to the exact location of its supporting evidence — every citation opens to its passage.
In practice
- Notes and annotations anchored to a passage, not to a whole file
- Links connect sections across sources — the relations you saw, kept
- In shared collections, every contribution is attributed to its author
- Structure exports with everything else — it stays yours
