Getting started looks bigger than it is. Chaptrix takes you in clear steps from idea to print-ready book — this guide shows the shortest path so your first chapter is ready in about half an hour.
1 · Enter or validate the idea
Start with a topic. If you’re sure, move straight on; if in doubt, your idea runs through the essay assessment and is checked against real Amazon demand. The viability score says plainly: write, differentiate or skip.
2 · Attach your sources
Upload documents, transcripts or notes. Through retrieval the agent writes from your material instead of inventing — so the book stays in your substance and your voice.

Why the agent doesn’t make things up (RAG)
RAG is simpler than it sounds. Before the agent writes a sentence, it first looks things up in the sources you uploaded — like an author reaching for the shelf instead of guessing from memory. “Retrieval” means exactly that: look it up first, then phrase it.
That brings two benefits. Your book stays factually correct, because every statement is backed by something in your material. And it sounds like you, because the agent draws on your wording and examples instead of generic filler. Without this step an AI would sound plausible but invent facts — with RAG it stays anchored to your substance.
3 · Generate & review
The agent produces chapter by chapter. You review, correct outliers and set the direction. Typesetting, cover and export then run automatically — including verified citations and an accessible PDF.
The hardest part of a book is the start. Chaptrix takes exactly that off your hands.
The result is an EPUB3 plus print-ready PDF with best-7 keywords and an EAN-13 cover — ready to upload to KDP.
