The Draftline editor: manuscript panel, floating page, and Writing Dashboard

What Draftline does.

A novel is a set of chapters in three sections, a cast that has to stay consistent across all of them, and a manuscript that eventually has to leave as an EPUB or a print PDF. Each tool below works on the whole book rather than on the page in front of you. If you are here looking for a free alternative to Scrivener, Atticus, or Reedsy that works offline, the comparison covers the differences.

The page
You write on a floating page set in Merriweather, with paragraph indents, a ruled chapter heading, and the ⁂ scene break already in place, so the draft reads the way the printed book will. Front matter, body, and back matter are separate sections in the manuscript panel, and you can drag chapters between them.
Characters Codex
Once a cast grows past a dozen names, remembering who was in which chapter becomes its own job. Draftline reads the manuscript and builds the codex for you, with a chapter-by-chapter presence map for every character, the people they share scenes with, and their first appearance, all detected on your machine and corrected with a merge or a split when a name comes out wrong.
Read Aloud
Reading a chapter aloud is the oldest editing trick there is, and most writers skip it because it takes an hour. Read Aloud does the reading with a neural voice that runs entirely on your computer, underlining each sentence as it goes, and in cast mode each character gets their own voice while the narrator keeps the tags.
Writing Dashboard
You set a daily goal and a target length, and the dashboard shows how today went, how many of the last seven days met the goal, and how fast this session is moving in words per minute. A per-chapter breakdown with the average, shortest, and longest chapter is usually enough to find the part of the book that needs another pass.
Spelling and grammar
Word processors have checked grammar for thirty years, and most manuscript editors still do not. Draftline checks spelling, grammar, and a separate layer of usage and style as you type, with deterministic rules that run on your machine, and confirmed character names join a project lexicon so an invented surname is never flagged as a typo.
Import and export
Your book is one file on your disk that you can back up, keep in a synced folder, or open ten years from now. You bring an existing manuscript in from EPUB or DOCX, and when it is finished you export an EPUB for storefronts, a DOCX for an editor's track changes, or a print-ready PDF with trim size, bleed, and crop marks.

Automatic light and dark theme.

If you write in the evening, the bright page that suited the afternoon is the wrong page by nine o'clock. Auto theme follows sunrise and sunset at your location, crossfades the studio to dark as the light goes and back at dawn, and plays a short sky animation in the title bar while it happens. You can also pin light or dark and ignore the clock.

Import.

If the book already exists as an EPUB or a DOCX, you import it and Draftline rebuilds the chapters, the front and back matter, and the scene breaks on the way in. The same three formats come back out when you export.

An optional plugin for editing prose you already wrote.
The editor contains no AI. The AI Studio is a separate plugin, disabled on a fresh install, and until you connect a provider of your own it cannot send anything anywhere. Once you switch it on, it runs line and copy edits over a passage you select and shows each change as a diff you accept or reject.
