Who made it
Built by someone whose own book AI ignored.
Robert Prime runs publishing.co.uk, the UK book formatting and discovery company, and wrote google.panic.repeat. When he asked the assistants about health anxiety books, his own was named twice in 72 answers. Book Score was built to measure that gap honestly and show the way to close it. SpineRadar is its front door.

Asks ChatGPT, Claude and Gemini what readers ask
Three questions a real reader would type, without naming the book: does the assistant know it, what are the best books of this kind, and what should someone with this reader's problem read. ChatGPT and Claude search the web live. Gemini answers from memory.
What are the best books about overcoming health anxiety and panic disorder? Give me about 10, with the authors.
Named: Overcoming Health Anxiety by David Veale and Rob Willson, DARE by Barry McDonagh, and 8 more.

Checks where AI looks for books
Goodreads, Open Library, Wikidata, Wikipedia, YouTube, Reddit and your own website. These are the sources the assistants read and cite. A book missing from them is a book AI cannot vouch for.

Our standard
Three things you can hold us to
A score is a diagnosis, not a promise. Nobody can guarantee sales or rankings, and we won't.
Real answers, never simulatedEvery answer is a live reply from ChatGPT, Claude or Gemini to a question a reader would ask.
Fixed rules, same score every timeThe same answers and the same page always give the same score. Nothing is left to a mood.
We never log in to your AmazonWe read public pages only. You paste the fixes yourself, or we do it with you, with your OK.
Questions
Common questions
What do I need to give you?
Your book's Amazon link, on amazon.co.uk or amazon.com. Nothing else to start. The result opens with your email, so we can send you the report link.
What does the free scan actually run?
A real check: your Amazon page read and scored, three reader questions asked of ChatGPT, Claude and Gemini (nine real answers), and the web sources AI reads checked for your book. It takes about a minute.
Is this the same as Book Score?
Yes. SpineRadar is the front door to Book Score, the book discovery audit made by publishing.co.uk. Your report opens on bookscore.publishing.co.uk and stays there.
Can AI really change book sales?
Readers increasingly ask assistants what to read next, and the assistants name a small set of books again and again (see the AI Shelf above). Being on those lists is a route to readers. We measure it and show the fixes. We do not promise sales.
Do you log in to my KDP or Amazon account?
Never. We read public pages only. You make the changes yourself, or with us on the Done for you plan.
What about books not on Amazon?
Use the title check on Book Score. It finds the book by title and author and runs the same questions.
