The walkthrough
7:48 · Home, Write, Characters, Preview, Design, Publish and Listen, start to finish.
01 How it works
Four steps, in the order a book is made.
In Standard mode there are only a dozen tools, named in plain words. A gold speech bubble appears next to the one to click next, and it can speak the hint aloud. When you want everything, switch to Advanced. Your book is never changed by switching.
Write
Draft chapters with notes, snippets, goals, Focus mode and writing sprints.
Add pictures
Bring in your artwork. Originals are copied safely and never changed.
Design pages
Place words and pictures on true-size pages, with styles for every genre.
Publish
Check the whole book, then export for print, ebook or Word.
02 See it
The real app, on a real book.
Every picture here is the finished app running on a sample book. Click any screenshot to enlarge it.

Everything you need to finish a manuscript, and nothing shouting for attention.

Natural voices
A natural voice is built in: Read Aloud works offline with nothing to install. Turn chapters into audiobooks and podcasts, and optionally use your own ElevenLabs voice.
AI on your terms
Use your own Claude, OpenAI or local Ollama. You see exactly what is sent, nothing is changed without your approval, and any chapter can be kept private.
