Shelf feature
Chat across your library
The /study-ai workspace is multi-turn chat with scope filters — LIBRARY, NOTEBOOK, TOPIC, or PAGE — plus optional relevancy documents.
What you get
- Compare themes across multiple PDFs in one thread
- Attach an outline to focus answers on selected topics
- 30 messages per thread free; 300 on Premium
- Server-side history with automatic trimming
When revision spans an entire subject folder, page-level ask is not enough. Library-scoped chat retrieves the right excerpts from every indexed document in that scope.
