Start with Chapbook

What Chapbook makes

Chapbook turns a short brief into an outline, editable chapters, a designed interior, a cover, and files you can take elsewhere. The finished downloads are a digital PDF, an EPUB 3 file, and a 1600 × 2560 cover JPEG.

You approve the plan and can edit every word. AI output can be inaccurate, so checking facts, rights, and the final manuscript remains your responsibility.

Create your account

Start with your name, email, a password of at least eight characters, and agreement to the terms. Google sign-in also appears when it is enabled. After email sign-up, open the verification message Chapbook sends before continuing.

Already have an account? Sign in with your password or choose Email me a sign-in link. Forgot password? sends a reset link. A brief begun on the landing site survives the sign-up redirect, so you do not need to type it again.

What you can do free

You can judge the plan and sample before deciding whether to subscribe. The Free plan includes one project, a complete editable outline, a sample chapter of up to 2,500 words and one redo—or the whole book when it is that short—one batch of cover candidates, every look, and watermarked PDF and cover previews.

Paid actions show their Book Credit estimate before work starts. See current plans and prices when you are ready for the full manuscript or clean files.
