# Quill

> Quill is a local-first book IDE for serious authors: it takes a book from first draft to
> typeset print PDF and ebook, and keeps the whole project as plain files on your own disk —
> no cloud, no account, no lock-in. Published by Mauricio Longo under the Greisson imprint.

Quill is desktop software you download and run on your own computer. It is in open beta on
**Windows and Linux** today; **macOS is planned** (no date set). A license covers every
platform Quill runs on.

**Price:** buy once for **$75** today; the price becomes **$149 for new buyers on 1 December 2026**,
and a license bought at $75 stays $75. A purchase is a **perpetual license with every 1.x update
included — not a subscription**. Try free for **30 days of actual use** (days you don't write don't
count), no account and no credit card; after you buy, a **14-day refund** applies, no questions asked.

## What Quill does (the facts only we can state)

- **A project is a folder of ordinary files** — Markdown for prose, YAML for structure, on your own
  disk. You can open, read, edit, back up, and version-control them with any tool; there is no export
  step and nothing to unlock. Quill works fully offline: no account, no cloud, no activation server.
- **Everything you can do to the book in the app, you can also do from the CLI.** The bundled
  `quill` CLI is a 1:1 surface over the same core the app uses, so any AI agent you already use
  can drive Quill from outside — reading and writing the book directly. There is **no AI inside the
  editor**; your AI policy stays yours.
- **A typed story bible** — characters, places, things — with structured fields, and entries that can
  be **scoped to one book or shared across a whole series**.
- **A plot board** that lays the chapter spine against thread and obligation lanes.
- **A promises ledger** that tracks setups and payoffs through their lifecycle as open, kept, or broken.
- **Check Packs** — deterministic, rule-based style and prose-mechanics checks (echoes, repetition,
  pacing, dialogue mechanics) you can read, edit, and share. No black boxes. A separate built-in
  offline grammar checker runs alongside them — English, Portuguese, Spanish, and French, sixteen
  regional variants as downloadable packs — and is not itself pack-editable.
- **Native Scrivener (.scriv) import** — preview what will import, then apply.
- Plus: binder, corkboard and outline; parts and acts; a WYSIWYG editor with Markdown underneath;
  offline spell-check in English, Portuguese, and Spanish (five dictionaries); a free brainstorming canvas; annotations with a
  review inbox; snapshots with visual diff; and built-in typesetting to print-ready PDF and EPUB
  (KDP trim sizes, house styles, large-print, multiple editions in one export).
