AI Assistant
Chaptery includes no AI model. An optional Assistant connects to OpenAI or Claude on your own API key, paid to that provider, or to a local Ollama model. It automates tasks in Chaptery, not your story, and runs only when you send it a request. One request can change or delete chapters, scenes and world entries without the app stopping to ask at each step. The text it reads, which can include your open chapter, goes to the model you choose.
Writing dashboard
Set a daily word goal, watch your streak and see how many words you wrote each day.

Free trial
The full product for 30 days with one book. No credit card needed.
Cloud Sync
Your books sync, so you can open them in Chaptery on any Mac or Windows computer you sign in on. You need to sign in to create or edit a book.

By day I'm a software architect at a large software company, and I've been building software for over 30 years. Chaptery started at home, though.
Both of my kids love stories. My son dove into a sprawling fan fiction and quickly outgrew Word and Google Docs. He was managing his characters, locations and lore outside his manuscript, and keeping it all in sync took more time than the writing. It got discouraging. My daughter makes up funny short stories, and her characters had nowhere to live from one story to the next.
We looked around for something that tied the drafting to the world behind it. Nothing we found quite fit them, so I built Chaptery for them.
You write in a desktop app for Mac and Windows. You build your characters, locations and events in your browser, and you can keep them open in a window beside the chapter, on a map showing how you've connected them. They can carry across a whole series. The editor shows your book's fonts and chapter openings as you write, and you can print or export a PDF, EPUB or Word file.
There's an optional Assistant too, which automates tasks in Chaptery rather than writing your story. It runs on your own AI key or a local model and only when you send it a request. One request can change or delete text without the app stopping to ask at each step, and the text it reads goes to the model you choose.
After I built it, I started following authors online and saw a lot of them having the same problems. So Chaptery is for any author now, not just my kids. I'm still building it, and authors can request features and vote on them.
The desktop app is written in C# on .NET, with Avalonia for the interface, so the Mac and Windows apps are built from largely the same code. The editor is built with TipTap. trychaptery.com, including the World Builder and Storyboard, is built with React and TypeScript, and the cloud services run on AWS.
