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.
