Kernel
Chapter summaries, read aloud
$0.99
Every chapter of your books in plain words. Read it in a minute or hear it explained, in English, French, Spanish or German.
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. Read one, or press Listen and hear it explained by a narrator while each word lights up. Download a book and it plays with no connection. Set a sleep timer that fades out.
Highlight a line and it comes back in Today's five. Search finds words inside your chapters, or ideas close in meaning. Write a note under any chapter. Export everything as Markdown.
Bring what you already have: your Goodreads shelves, Kindle highlights, Readwise, EPUB and PDF files, or photos of the pages.
Your summaries are yours. They sync across iPhone, iPad, Mac and the web, and deleting your account deletes all of it.
