About Knowledge Observatory
Knowledge Observatory writes a researched book on your iPhone. Describe a topic. The app outlines chapters, writes prose, and adds illustrations. Your first book is free. Later books cost one credit. Buy credits as a consumable in-app purchase (1, 3, or 10 books). Sign in with Apple or email. Books stay in your library so you can read, jump the table of contents, and zoom illustrations.
