Adventure novels for Amazon KDP

Write an adventure novel with AI

The hero sets out, faces trials and comes back changed. Before the chapters you set up the journey: what the hero lacks, the mentor, the ordeal. The app checks that it closes, and the AI writes scene by scene.

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 skiff was already half in the water when Ines heard the dogs come up from the levee road.

She threw her pack over the gunwale and pushed. Mud took her boot and kept it. She let it keep it.

"You come back by Sunday," her uncle said from the bank. He didn't move to help. "Or you don't come back."

"I know how it works."

"You don't." He held out the lantern, then pulled it back an inch, the way he did with everything. "They watch the far side at night. You'll want to be across before the moon."

Ines took the lantern. The current grabbed the bow and turned her toward the dark water, and the dogs reached the top of the levee behind her, barking at a place she wasn't anymore.

Frequently asked questions

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.
