Write your first great book.
CoWrite is an AI co-writer that talks your book out of you. It remembers every discussion, captures your decisions and themes, and turns them into a chapter-by-chapter structure you can actually write from.

I keep telling clients the same onboarding story — maybe that's my opening chapter?
That story shows up in almost every conversation we've had — it's clearly a recurring theme. Last week you decided the book is for founders in their first two years. What does that story teach them specifically?
A co-writer, not a text generator
Most people don't fail to write a book because they can't write. They fail because the ideas stay scattered. CoWrite fixes that.
Talk it out
Threaded conversations per book. CoWrite asks the probing questions a good editor would — and pushes back when an idea is thin.
It remembers
Decisions, themes and insights are captured automatically into your book's memory. Pin the ones that matter; delete the noise.
Structure on demand
One click turns months of conversations into a versioned outline — parts, chapters, key points — grounded in what you actually said.
Take it anywhere
Export your outline and conversation-derived notes as clean Markdown, ready for Scrivener, Word, Notion or your editor.
How it works
- 1
Start a book project
Give it a working title, pick a category — business book, memoir, how-to or thought leadership — and say who it's for.
- 2
Talk through your ideas
Chat whenever inspiration strikes. CoWrite keeps the thread, remembers your decisions and connects the dots across sessions.
- 3
Generate your structure
When you're ready, CoWrite drafts a full chapter outline from your conversations. Refine it, regenerate it, export it — then write.
Simple pricing for serious writers
Start free. Upgrade when the book gets serious.
Frequently asked questions
Does CoWrite write the book for me?
No — and that's the point. CoWrite is a collaborator: it interviews you, remembers what you say, challenges weak ideas and organises your material into a structure. The voice and the stories stay yours.
What kinds of books does CoWrite support?
CoWrite is built for non-fiction first: business books, memoirs, how-to guides and thought leadership. Fiction support is coming soon.
What does CoWrite actually remember?
After each exchange, CoWrite captures decisions, themes, insights and references into your project's memory. You can see everything it remembers in the sidebar, pin what matters and delete anything that's wrong.
Can I export my work?
Yes. On the Solo Writer plan you can export your chapter outline and conversation-derived notes as Markdown, which opens in Word, Scrivener, Notion, Obsidian and virtually every writing tool.
Is my writing used to train AI models?
No. Your conversations and outlines are yours. We use them only to provide the service to you — see our Privacy Policy for the details.
Can I cancel anytime?
Yes. Manage or cancel your subscription from the billing page any time; you keep Solo Writer features until the end of the paid period.
