AI co-author for books + every edit is a diff you approve
Pinery is the self-publishing studio for Mac. 2.0 adds Prose, an AI co-author that works from the pages you've already written — every edit arrives as a diff you accept or reject. Write, design, and export ePub 3 or PDF. Your files stay plain Markdown.
Pinery 2.0 is out today — and it's our biggest release yet 🎉
Prose is an AI co-author that lives beside your manuscript instead of in a browser tab. It doesn't start from a blank prompt — it works from the pages you've already written, so a new chapter or a continuation comes back in your pacing and your vocabulary, not the flat, over-polished register you get from pasting three paragraphs into a chat window.
Three decisions shaped it:
You see exactly what changed. Prose edits happen inside your manuscript, and every one arrives as a labeled diff — grammar, word choice, formatting — that you read and accept or reject on its own. No copy-paste, no guessing or using another app.
Your files stay yours. Plain Markdown on your Mac or iCloud — cancel me tomorrow and your book still opens anywhere. Prose pulls in only what a request needs: a paragraph for a line edit, the whole manuscript when you ask for a structural critique. The privacy page spells out where it goes.
Not locked to one model. Leave it on Auto, or pick per task from Anthropic, OpenAI, and Google — something fast and cheap for a line edit, the strongest one for a first draft.
Around that: skills for the ways writers actually get stuck (/beta-reader, /line-edit, /developmental-edit, /drafting-partner, and /create-skill to teach it your own), illustrations that read the scene before they draw, chapter notes, real typography, a Kindle e-ink preview, and ePub 3 / PDF export.
