Shelf feature
Share Shelf with classmates
Invite Shelf users by email with view or edit access. Recipients see Shared with me in their library; owners keep control of rename and delete.
What you get
- Share individual pages — not whole collections
- View vs edit per collaborator
- Optional link access for signed-in users
- Save a copy, or send the PDF back to Telegram
Search for “share Shelf” when you need controlled PDF sharing instead of chat attachments. Study groups pass coaching PDFs; teachers share lesson handouts. Annotations stay per person, and recipients can fork a copy when they need their own highlights.
