Kernel
Chapter summaries, read aloud
USD 0.99
Chapter summaries of the books you read.
You finish a book and a month later you remember one idea. Kernel keeps the rest. Every chapter, in plain words, readable in a minute.
Open a book and see its chapters. Open a chapter and read it, or press Listen and hear it explained by two hosts while each word lights up as it is read.
Your summaries are yours. They live in your account, sync across iPhone, iPad, Mac and the web, and deleting your account deletes all of it.
Sign in with Apple or email. Share any summary with a link.

Bookrank is now Kernel. A new gold look and our own typeface, a short welcome for first-time readers, and one narrator who explains each chapter. After you update, sign in once. If you use email, reset your password once.
