Nested Collections
Organize your research your way
Collections 2.0 lets you build a structure that matches how you think. A tree view shows your nested collections at a glance—move papers between them with simple drag-and-drop. Group by project, topic, or timeline. Filter files by status, source, or collection so you see exactly what matters. Add flat tags for quick cross-cutting labels without deep nesting.

Collaborate at the collection level
Start discussions at the collection level and add inline comments on passages to keep feedback anchored to the text. Invite your team to contribute—each collection can be private, shared, or public. Collections 2.0 turns your library into a flexible workspace where structure, discovery, and collaboration work together.
