Romance novels for Amazon KDP

Write a romance novel with AI

Before the chapters you set up the couple: what each one carries, what binds them and the kind of story. The app checks what romance readers expect: an early meet, a breakup near the end and a happy ending.

An excerpt written by CoAutor

This excerpt was written by CoAutor for a sample book, unedited. In your book, the text follows your tone, your material and your revisions.

Sample excerpt

The ladder was wrong. Anyone could see it—two legs sunk in the soft dirt of the flower bed, the whole thing leaning toward the bakery's front window like it had somewhere better to be.

"You're going to put your elbow through that glass," June said.

The man on the top rung didn't look down. "I've got it."

"You've got about four seconds."

He got three. The ladder slid, he caught the gutter, and the string of café lights he'd been hanging came down across her shoulders in a tangle of warm bulbs and wire.

He landed in the mulch beside her. Dusted his hands. Looked at the lights draped over her like a shawl.

"Could've been worse," he said.

"Could've been you under them."

Frequently asked questions

Can I write a romance without a happy ending?+

In this format the app checks for an ending with the two together, because that is what romance readers expect. For another kind of love story, use the Fiction format, with no genre recipe.

Does the text sound like it was written by AI?+

The automatic review strips out repeated phrasing, overstatement and the "not X, but Y" formula, the most common tell of AI text. You set the tone and your own voice before writing, and review each part before moving on.

Do I need to keep the tab open while the AI writes?+

No. Writing runs on the server: you ask for it, close the tab, and an email tells you when it is done.

How much does it cost?+

You pay once per book, by size: up to 15,000, 30,000 or 50,000 words. No monthly fee, and the package does not expire. The account is free: you can create the book and see the path before paying.
