Frequently asked questions
Is the Litheca book summarizer free?
Yes, completely free, with no account required to generate a summary. Signing up (also free) adds extras like a synced library, ratings, and commenting.
How are the summaries generated, and can I trust them?
Each guide is AI-generated, but only after the book is verified against real catalogs (Google Books and Open Library). Our rule is simple: no data beats wrong data. Anything we can't verify (awards, ratings, quotes, free-ebook links) is left out rather than invented.
What do I get besides the summary?
A full study guide: chapter-aware deep summary, character profiles, key themes, notable quotes, reading-time planner, similar books, reader ratings and comments, plus a comprehension quiz whose answers are backed by quotes verified against the source text.
Which books does it work for?
Anything findable in the major catalogs we search (over 20 million records spanning fiction, non-fiction, and classics), plus popular web novels and manga through curated community wikis.
How long does it take?
Popular books open in a few seconds. A book being summarized for the first time takes up to a minute, and if the free server was asleep, the first request may add a short wake-up wait. We show progress the whole way.
Do summaries replace reading the book?
No, and we don't pretend otherwise. Litheca works best as a companion: decide whether a book deserves your time, refresh one you read years ago, or test your understanding after finishing it.
