Billing rules

Cache hits do not consume credits; credits are deducted only on a cache miss that triggers the full pipeline. Requests with prohibited words or that are not book searches are blocked, but credits are still deducted.

You don't need the title or the author. Just describe whatever you remember about the book in one sentence, and let AI do the rest.

Write down the clues you remember

A plot fragment, a character's name, the era or setting, the cover color, how the book felt, or even half a title or just the author's surname — anything goes. The more specific you are, the better the match.

Say which kind you want

To find one particular book, describe it. To get a stack of books on a theme, say "give me a reading list about…" or "recommend a few…". The system detects the type automatically.

Open a result for details

Every card opens a detail page with the summary, rating, author and publisher, so you can decide whether to read it. If nothing fits, rephrase and try again.

Book lookup: find one specific book

e.g. "A sci-fi novel about time travel — the hero goes back in time with a clock, and the author seems to be French."

Reading list: get a stack of books

e.g. "Give me a beginner reading list on AI ethics" or "Recommend a few gentle short-story collections for bedtime."

Click a card under “Others are searching” to reuse a result someone already searched — it is faster, and cache hits usually cost nothing.
One account (or one IP when signed out) can run only one search at a time. Waiting in the queue is free; credits are charged when your turn comes: 1 for a book lookup, 2 for a reading list.
You get free searches every day: 1 without signing in, 3 when signed in, 5 after daily check-in. They reset at 00:00 (UTC+8). After that, credits are used, and credits never expire.
If nothing turns up, rephrase and try again: add the author, era or genre, or say “something like <book>”, and your hit rate will improve.

AI results may be incomplete or off. Please rely on the book detail page for the author, publisher and year.
