Everything to master Chaptrix.
Understand the pipeline, learn the features in depth, and automate everything via the API.
How Chaptrix works
Five phases, one continuous agent.
Validate
The agent checks your idea against real Amazon demand. Keepa and BSR data give a confidence band and a viability score: write, differentiate or skip.
Write
Your sources become the manuscript — chapter by chapter, in your voice, with RAG instead of robotic prose.
Design
Publishing-grade typesetting (Typst) and the pixel-parity cover studio produce a print-ready book.
Verify
Citations are verified against Crossref/OpenAlex, and export is PDF/UA and PDF/A compliant.
Publish
KDP launch kit plus 200+ marketing assets — from finished book straight into the campaign.
