50+ Tiptap extensions — pagination, citations, footnotes, track changes, comments, bookmarks, math, and more.
Scrivener import
Bring an existing Scrivener project in with its binder structure, documents, and formatting intact — and keep writing.
Story bible
Characters, locations, and facts — auto-generated from your draft, kept editable, mentioned in chat as @-context.
Project-wide search
Full-text search across every document with regex, case-sensitive, and whole-word modes. Find passages in milliseconds.
Multi-format export
PDF, DOCX, EPUB, Markdown, TXT — compile entire manuscripts or selections with full formatting control.

AI authoring
Ghost text continuations, inline rewrites with diff review, and batch authoring across multiple documents at once.
Focus modes
Typewriter mode, read mode, distraction-free composition, and word-count goals — for the days when the page needs to disappear.
Polyz for iPhone
A writing surface that lives in your pocket. iPhone-only, portrait-locked, designed for the way novelists actually use phones. Launching after the desktop app stabilizes — your Pro subscription will already be on it the day it ships.
Three-panel swipe carousel
Binder, editor, AI chat — swipe between them. Designed for thumbs.
Offline-first
Edits land in local SQLite first. Sync drains when you're back on the network.
Full sync with desktop
Every project, snapshot, and note stays in step across devices.
Native rich text editor
Headings, lists, blockquotes, footnotes, links. AI ghost text inline.
Universal account — when iOS ships, you'll sign in with the same Polyz account you already use on desktop.
