List any book, lot or set in seconds, without scanning or entering ISBNs. No need to link your eBay or Amazon account.
Snap a few photos. Our AI writes the whole listing, with a suggested price, and hands you an upload file. You upload it yourself, so no app ever gets inside your seller account.
No card needed. Plans from $9.99/month.
Your selling account stays locked in the vault.
Most listing apps make you sign in to eBay or Amazon and give them permission to manage your account. That's a stranger holding the keys to your store. BooksOnFly never asks for the key. It can't touch your account, because it never connects to it.
Connected apps work through sign-in and permissions. BooksOnFly never asks for either.
Private by design, not by promise.
We can't touch your seller account because we never connect to it. There's nothing to hack, revoke or worry about.
Nothing to hand over
No eBay or Amazon password, no sign-in screen, no "Allow access" button. Your seller account never meets our app.
Nothing to go wrong
No third-party app can post, edit or end listings in your store, or break when its access expires.
You stay in charge
You see the file first and upload it yourself. Nothing goes live until you say so.
Odd lots used to mean a lot of research. Now they take a minute.
Listing a set or a lot meant looking up every title and working out how to fill in each field. The AI does all of it, and it's just as good with the lots other tools choke on.
- Incomplete setsIt works out which volumes you have and which are missing, and says so clearly in the title and description. No surprised buyers.
- Lots you put together yourselfA shelf of random mysteries, a box from an estate sale, three cookbooks and a novel. It reads every spine and builds one clean listing.
- Antiquarian and collectible booksEditions, printings, bindings and flaws described the way collectors expect, in eBay's Antiquarian & Collectible category.
- No waiting aroundStart your next listing while the AI writes the last one.
Made for eBay and Amazon sellers who list from their phone.
Pick eBay or Amazon at the top of the screen. Either way, you get a file to upload yourself.

Frequently asked questions
Why doesn't BooksOnFly connect to my eBay or Amazon account?
Because it doesn't need to, and you shouldn't have to give any app the keys to your store. BooksOnFly writes your listings into an upload file. You upload that file yourself, so your seller account stays locked.
Will you ever ask for my eBay or Amazon password?
No. There's no eBay or Amazon sign-in anywhere in BooksOnFly, and no "allow access" screen. If anyone asks for those passwords in our name, it isn't us.
How do my listings get onto eBay?
When your batch is finished, tap Done and send the file to your email. On a computer, upload it in eBay Seller Hub (Reports → Uploads). All your listings are created at once, as scheduled listings you can check before they start.
How does it work for Amazon?
Amazon matches a used book to its existing page by ISBN. The AI reads the ISBN from your photo, checks it, writes your condition note and suggests a price. Once, at the start, you add the blank spreadsheet Amazon gives you in Seller Central. After that BooksOnFly fills it in for every batch, and you upload it in Seller Central.
Can it handle incomplete sets or lots I put together myself?
Yes, just as well and just as fast. For an incomplete set it lists which volumes are included and which are missing. For a made-up lot it reads every title and writes one clear listing for the whole group. Those go on eBay; Amazon lists books one at a time.
What about old, rare or collectible books?
Choose Antiquarian & Collectible. The AI describes the edition, printing, binding and flaws the way collectors expect, and the listing goes in eBay's Antiquarian & Collectible category.
Are the suggested prices based on live sales?
No. They are the AI's starting estimates. Every listing has a one-tap link to eBay's sold listings or the book's Amazon page so you can check and set the final price.
How does the free trial work?
You get 2 weeks free, up to 20 listings, with no card. After that, choose Starter ($9.99 a month for 40 listings) or Plus ($19.99 a month for 100). Pay yearly and get 2 months free. Cancel anytime.
What counts as a listing?
One listing is one book, set or lot the AI writes for you. Editing it, making the file again and asking for help don't count.
