Description

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.
