Simple plans

Free to write. Paid when you want the grounded co-writer.

Questions writers ask

What is an AI credit?

One credit is roughly one assistant message. Bigger jobs cost more: expanding a chapter is 4, a quality report is 3, a generated cover image is 5. Your Account page shows exactly what you have used.

Is the free plan really free?

Yes. One book up to 15,000 words, the editor, version history, Book Bible, 25 uploads and one quality report a month. The AI co-writer is the part you pay for.

Can I try the paid features first?

Every account gets a 14-day Author trial without a card. When it ends you keep your work and drop back to the free limits until you subscribe.

What happens to my books if I cancel?

Nothing is deleted. Your books stay readable and exportable as a watermarked sample; upgrading again restores full exports.
