Kosmos is a structured methodology for producing a book. From concept to first manuscript. Your AI organizes, researches, and reviews. You write every word.
I built Kosmos from the systems I used to produce four books. The pattern was the same every time: define what the book needs, gather material, track what you have against what you need, and let the gaps drive your next research round.
Define your book concept. Research the genre. Design a coverage framework: the themes and questions your book needs to address.
Gather material. Extract atomic entries. Track coverage against your framework. Gaps tell you exactly what to research next.
Study books you admire. Lock your outline. Create chapter briefs that describe what each chapter needs, including what is still missing.
You write the chapters. The AI surfaces source material, reviews your drafts, tracks progress, and checks for consistency. Your words, your book.
AI never writes prose. It organizes your research, tracks what is covered, helps you design your outline, and reviews your drafts. You write every word of the manuscript.
A methodology proven across four published books. Not a template. A system.
A coverage-driven feedback loop that prevents aimless research. You always know what the book needs and what is missing.
Four research frameworks for different book types: interview extraction for memoir, the Greene notecard method for research-heavy nonfiction, structural analysis for studying admired books, and source material indexing for existing writing archives.
Templates for chapter briefs, coverage maps, book spines, and a voice guide that helps you define your own writing style.
Everything runs inside your own Claude Code. You bring your AI subscription. Kosmos brings the methodology.
