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
You came home tonight and the kitchen table was still covered. Mail, a charger, two bags you meant to unpack Sunday. You moved a stack to eat, and that was dinner.
Here's what I want you to notice: you're not lazy, and you're not disorganized in some permanent way. You're running a house with no system for where things land when they come in the door. Everything you own is sitting in the last place you set it down.
By the end of this chapter, you'll have one surface in your home that stays clear — chosen deliberately, cleared in under forty minutes, and protected by a rule you can follow when you're tired. One surface. That's the whole job.

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.
Does the AI make up stories about me?+
No. It only uses the stories you tell it. Without them, it illustrates with situations from the reader's life, not episodes from yours.
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.
