Will you like this book?
Hunch learns your taste, then predicts how much you — specifically — will enjoy any book. Point your camera at the cover, or type the title.
Try it on a book
No account needed. Two quick answers, then the book you're wondering about.
The book you're wondering about
Add the author if you know it — it's the quickest way past two books with the same name.
How it works
- 1
Tell it your taste
Pick the genres you love, the moods you're after, and the things you can't stand. Takes about two minutes.
- 2
Add a book
Photograph the cover in a shop, or type the title. Hunch works out which book you mean.
- 3
Get a score that's yours
A prediction out of 5, broken down across eight things that decide whether you'll like it — and the reasoning behind each.
Rate books as you finish them, and the predictions get sharper.
Same book, three readers
This is the whole idea. One book, and it is a different recommendation depending on who's asking.
Loves sci-fi and adventure · big, epic, funny · avoids romance

A worked example, not a live prediction — real ones are written for your profile once you're in.
Your data, plainly
- What's stored
- Your email, the books and ratings you add, and basic usage events — which screens get opened, which buttons get pressed — so I can tell what's confusing people.
- Who can see it
- Your library is locked to your account in the database; nobody else signed in can read it. I can see the usage events, because working out what to fix is what they're for.
- What your email is used for
- Confirming your account and resetting your password. There is no newsletter and no marketing to opt out of.
Fair questions
What do you keep when I try it without an account?+
Nothing about the book or your answers — the result is shown to you and then it's gone. To stop free tries being abused, Hunch keeps a scrambled version of your internet address for a day, which it can't turn back into the address itself.
Is my reading data used to train an AI?+
Each prediction sends the book's title and a summary of your taste to OpenAI's API, which is what writes the score. Data sent through their API isn't used to train their models by default. Your library itself stays in Hunch's own database.
What happens to the photo I take of a cover?+
It's sent once, to identify the book, and never saved. What gets stored is the title, the author, and the score — not your picture.
Will it stay free?+
Free for the whole alpha. If it ever costs anything, testers will hear it from me first — and nothing can charge you in the meantime, because there's no payment system built yet.
How accurate is it, really?+
Usually predictions are less than 0.5 stars off. But don't take our word for it — try it yourself.
