Kern

About

You complete a meaningful book and feel transformed, yet weeks later you struggle to recall its key elements. Kern solves this. Submit a book title and it generates a concise deck of memory cards. For non-fiction, it extracts the central concepts. For fiction, it captures the characters, plot twists, and significant moments. There are no highlights, exported notes, or manual card creation. The reviews are delivered on a spaced schedule, designed to reach you just before you would forget each one. It functions with both physical books and library copies. The service does not use streaks. You can try it with two books at no cost.
