Plain files, all the way down.

Files

Readable in any editor, yours to back up.

Everything Quill knows about your book lives in Markdown and YAML on your disk — readable anywhere, versionable, yours.

✓Works offline, forever. No connection required — not at install, not ever.
✓No account. Not even an optional one.
✓Downloads, not uploads. Optional update checks and language packs only — your book never leaves the machine; an update check sends just your license ID and app version.
✓No lock-in. Walk away any day; your book comes with you.

A visual diff between two snapshots of a chapter in Quill.

Versions

Your history, kept.

Save a version when it matters, snapshot the whole book at a milestone, and see exactly what changed — down to the word — between any two points. Deleted documents go to Quill's trash — those are always recoverable.

Versions per document, snapshots per book

Deleted documents always come back from the trash

Sync-safe

Plays fair with your sync folder.

Keep your project in Dropbox or any file-sync — Quill's on-disk journal is built for it, and if your sync tool forks a file, Quill notices and heals instead of silently losing an edit. It also tells you when something else edited your files while it was away.

Safe under file sync
Conflict copies detected and healed
Outside edits flagged on open

Quill's Scrivener import preview, showing exactly what will land before anything is written.

Arrive with your book

Bring the book you already have.

Import a Scrivener project — preview exactly what will land before anything is written — and start where you left off. Leaving is the same courtesy in reverse: your files are already yours.

Scrivener (.scriv) import with preview
Markdown projects open natively
No export ransom — there is nothing to escape

Sit in it for 30 days.

The trial is 30 days of actual use — days you don't write don't count. Buy once; every 1.x update is included.
