Field notes
The page describes several ways to feed material into a session: X bookmarks, a Chrome extension, an iPhone share sheet, or a PDF upload. For shorter sessions, it says the tutor can choose a saved item based on a requested time limit. The site also describes a user-correctable record of understood ideas, and says phone controls remain available from the lock screen during a call.
