It is a way to stop wondering what Anthropic's Claude says about you and your book. It is for any author, indie or traditionally published, fiction or nonfiction. The section above shows what goes in and what comes out. It checks Claude only, and it does not write or fix anything.

Wondering is harder than knowing, so run the tool to find out. Claude tends to know popular books in depth and lesser-known books thinly or not at all. A thin answer is common and says little about the quality of your writing.

It is easy to assume readers still search the old way. Many now ask AI for something to read, often describing the book they want without naming a title. If your book is not part of what Claude already knows, it cannot offer it to those readers. Seeing the gap now gives you time to work on it.

A made-up detail can feel like a punch, and it is also the most useful thing the tool can show you. When an AI does not know a book well, it fills the gaps with plausible guesses, even a made-up plot or ISBN. Read the wrong details as a map of where your online footprint is thin, and do not repeat them anywhere as fact.

It stings to hear nothing, and it is useful information rather than bad news. A blank is common for newer books and midlist authors. You know where to focus: your Amazon page, your Goodreads profile, and your author website, the places an AI is most likely to learn from next.

A friendly answer in the Claude app can be misleading, because Claude's own apps can search the web, which can make Claude look better informed than it is. Here you get a fair read on whether a reader's chat would mention you.

It is natural to want a way to simply tell Claude about your book, and you cannot submit it. You can strengthen the pages an AI is most likely to draw from, such as a dedicated book page on your author website, your Goodreads profile, your Amazon page, and reviews and media coverage. You can check those pages with Book Page Scanner and SEO/GEO Optimizer. Expect any change to take months to show up.

Yes, because one answer is only part of the picture and each AI knows a different set of books. You can see where your book is known and where it is invisible by trying ChatGPT Knowledge Checker and Gemini Knowledge Checker too.

Yes, and a backlist deserves it. Run the tool again with a different title. You can check your whole backlist one title at a time to see which titles Claude already knows and which are still invisible to it.

Waiting for results is hard, so it helps to know the pace. It depends on when your book and its reviews were published relative to Claude's training, and on how much has been written about it online. An AI's general knowledge updates on a training cycle, not in real time, so expect changes to your author platform to take months to show up.

It is natural to want to check early, and you can, but expect Claude to know little. Claude will not know an unpublished book. The tool is most useful once your book or your author name has something online for Claude to have learned from.

Yes. Author Media does not store, track, or view anything you post to this tool. The tools reach each AI through its business API with privacy set to the maximum, so the AI companies do not train on your words.

Claude Knowledge Checker is included with any Novel Marketing Patreon membership of $10 per month or more. That membership also unlocks more than 80 other author tools in the Patron Toolbox.
