Your Goodreads, with the ideas back.

Sign in on Goodreads' own page inside the app and your shelves come along: what you are reading, what you have read, what you want to read. Books you finished but never summarized wait in their own row, so the next one is obvious. Your Goodreads login stays on your device and never reaches Kernel.

Keep every chapter.

Your summaries stay in your account. Nothing is public unless you share it.
