As answered by people managing Code Effects and Hunch Books.
Hunch Books's answer:
Most book apps show you what other people thought — an average star rating from thousands of readers with different taste. Hunch predicts what you will think. You describe your taste once, then photograph any book cover or type a title, and Hunch gives a personal score out of 5, broken down across eight factors (genre, themes, writing style, pacing, characters, length, similarity to your favourites, and your dealbreakers), with the reasoning for each. It also shows the book's moods and content warnings, and it gets more accurate as you rate the books you finish.
Hunch Books's answer:
Many readers use it alongside Goodreads or StoryGraph: a tracker to log what they read, and Hunch to decide what to read next.
Hunch Books's answer:
Book lovers who buy or borrow books often and are tired of picking ones they don't finish — people who browse bookshops, library shelves and book sales and want a quick, honest "is this for me?" before committing. It also suits picky readers with clear dislikes who want to check a book's content and mood before starting.
Hunch Books's answer:
I kept buying highly rated books and abandoning them halfway. A 4.3 on Goodreads said nothing about whether I would like a book — the crowd's taste wasn't mine. So I built the tool I wanted: one that learns what I actually enjoy and tells me, standing in the bookshop, whether a book is likely to work for me. Hunch is made independently by one reader in Malaysia and is in early access, shaped by feedback from its first testers.
