Mac writing app
A writing IDE for Mac, not another blank page.
ronoo is a native Mac writing workspace for people who need structure, sources, and recoverable drafts in the same place as the prose. One project holds the work. You decide what leaves it.

Capture ideas in Inbox, shape chapters in the Project Map, and keep notes and research beside the manuscript without silently promoting them into the draft. The Navigator, continuous manuscript, and Saved Views share one structure.
- Organize long manuscripts without turning every draft into a dashboard.
- File supporting material when you are ready — not when you first catch the idea.
- See the work as outline, continuous prose, or focused writing surface.

Every save stays a Moment
ronoo treats revision as history you can browse. Each save creates an immutable Moment you can compare, branch, merge, or restore. Old drafts are not overwritten out of existence.

Evidence stays fastened to the sentence
Pin documents, sources, and claims to the ranges they support. Pins survive edits, feed annotated editor copies, and keep publishing locked while a claim is flagged, unsupported, or orphaned.

Compile finished editions from one trusted project
Compile Recipes and Production Profiles produce editor, ebook, print, web, fact-check, and archive editions. Outputs include Markdown, plain text, DOCX, PDF, HTML, and EPUB.

Agents propose. You decide.
ronoo is not an AI writing app. On Mac you can optionally connect a supported agent with your own account or key. It receives only the context you approve, cannot see the Vault, and returns edits as proposal branches for review.
Built for Mac, sold once
$50 Direct purchase. No subscription. Free updates for a while after you buy; same-major updates stay free after that; a later major is a $30 upgrade when offered. Writing stays on your machine.

What is a writing IDE for Mac?
A writing IDE is a native workspace that holds the manuscript, research, revision history, evidence, and publish outputs together — not a separate notes app, word processor, and folder of exports.
Is ronoo only for novels?
No. ronoo is built for longform nonfiction, journalism, books, and any Mac project where structure, sources, and revision history matter as much as the prose.
Does ronoo replace my word processor?
ronoo is the place you draft, organize, pin evidence, and compile finished editions. You still export Markdown, DOCX, PDF, HTML, or EPUB when an editor or printer needs a specific format.
