Sample excerpt

Day 1 — Before the Coffee

You wake up and your mind is already running the list: the lunches, the text you forgot to answer, the thing you said last night that you wish you hadn't. Gratitude doesn't stand a chance against a list like that, not if you wait until the list is finished. So don't wait. Before your feet touch the floor, name one thing — the warmth of the blanket, the sound of someone breathing in the next room, the fact that you woke up at all. One thing, out loud or under your breath. You're not pretending the list isn't there. You're deciding what gets the first word.

Lord, before I ask You for anything today, let me thank You for one thing I almost walked past.

AI-generated, unedited.

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.
