Free tool
Free comp title finder
Tell it your genre, audience and premise. It suggests comparable titles for your query letter, checks each one against a book catalog and shows the publication year, so you can see which are recent.

What you get
Up to six comparable titles for your query letter, each with its author, the publication year where the catalog lists one, and a sentence on what your book shares with it.
It takes about half a minute, and you don't need an account. Books older than 5 years are flagged, so you can pair them with something recent.
Every title is checked before you see it
An AI model on its own will sometimes name a book that doesn't exist, or give a real title the wrong author. Put one of those in a query and an agent will notice.
So the model only suggests. Each suggestion is then looked up by title and author in Google Books and in our own catalog of comparable titles. A book neither one has is left out, and the result tells you how many were.
If the catalog can't be reached at that moment, a suggestion is shown with a "Check this book exists" label instead of being marked as found. Treat those as leads, not facts.
What makes a good comp
- Recent: published in roughly the last 5 years, so it shows where your book sits in today's market.
- Same category: the same genre and age group. A young adult novel needs young adult comps.
- Not a phenomenon: skip books with film franchises or decades on bestseller lists.
- True: you've read it, and the comparison holds for tone, premise, structure or readers.
How to use them in your query
Comps usually go in the same paragraph as the title, genre and word count. Name two or three, and say what your book shares with each one, not just two titles and a "meets".
A comp is a positioning signal, not a claim about quality. It tells an agent where the book would sit in a bookshop and who would buy it.
The full guide to comp titles
Our guide collects what agents have published about comps: how recent is recent enough, how big is too big, and how to phrase them.

Frequently Asked Questions (FAQ)
Is the comp title finder free?
Yes, with no signup. Free tools share a fair-use limit of 6 runs every 12 hours.
Are the books real?
Each suggestion is looked up in Google Books and in our own catalog before it's shown, and books neither one has are left out. If the catalog can't be reached, a suggestion is labeled "Check this book exists" instead.
Why did I get fewer than six?
The finder asks for six and shows only the ones it could confirm, each once. A shorter list means some suggestions were left out, which is the point.
How recent should comps be?
Agents quoted in our comp titles guide ask for books from roughly the last two to five years. Books older than 5 years are flagged here.
Should I read the books before naming them?
Yes. A comp tells an agent your book shares its readers, so you need to know it does. Use this list as a starting point for your reading.
Is my premise stored or used for training?
No. It's sent to our AI provider to suggest the books, and only the suggested titles are looked up in Google Books. StoryWith AI doesn't save it, and we don't use it to train AI models.
Can I use it in another language?
Yes. Write your premise in any language and the reasons come back in that language. Titles are shown as the catalog lists them.
