Lore & LilacCo-authoring
Two writers, one book, no lost sentences
Invite a co-author to a book by email. You both write in the same chapters and scenes; the studio shows who is in which scene, records who saved each version, and never lets one person's words quietly replace the other's. It works scene by scene, not keystroke by keystroke.
No AI involved Co-authoring involves no AI. Only the book's owner can start AI runs, so a co-author never spends the owner's allowance.
What you get
Co-authoring, in detail
- Invite a co-author to a single book by email from the book's People page; the link works once and expires after 14 days, and you can withdraw it
- Co-authors per book, set by the owner's plan: 1 on the trial, 2 on Core, 5 on Studio. Pending invitations count
- Your co-author needs a free account, not a plan. The book appears in their library under “Shared with you”
- Presence: small markers in the binder show who has which scene open. Open a scene someone is writing in and it opens read-only — “Maya is writing in this scene” — with Edit anyway
- Clear ownership of each change: version history says who saved each version, and comments show who wrote them
- Co-authors write, edit, add chapters and scenes, comment, and work on the story bible, plans, notes, saved views and the revision desk
- Owner only: AI runs, exports, imports, publishing, reading links, deleting the book and billing
- The owner can remove a co-author at any time, and a co-author can leave; deleting the book ends everyone's access
How it works
In practice
Invite
Open the book's People page and enter your co-author's email address. They get a link naming you and the book — and nothing from the manuscript.
Accept
Your co-author signs in or creates a free account, then accepts. The book joins their library under “Shared with you”; nothing else of yours is visible to them.
Write side by side
You can both work in the book at once. The binder shows who is where, and a scene someone is writing in opens read-only until you choose Edit anyway.
Sort out overlaps calmly
If you both changed the same scene, nothing is overwritten: the second save asks you to compare both versions and keep one, the other or both. History shows who saved what.
Where we draw the line
What it never does
- Show your co-author your other books, your account, your billing or your AI allowance
- Let a co-author spend your AI allowance, export your book or create reading links
- Let one writer's save silently replace the other's
- Show a co-author's email address to anyone but the book's owner
- Put manuscript text in invitation emails
These follow from our commitments. The studio never writes, suggests or rewrites your prose, anywhere.
Before you start
Questions writers ask
Can we type in the same scene at the same time?
Not character by character, as in Google Docs. Co-authoring here works scene by scene: the studio shows who is writing in which scene and opens that scene read-only for the other person, who can still choose Edit anyway. If you both edit it, nothing is lost — the second save asks which version to keep, or keeps both.
Does my co-author need to pay?
No. They need a free account. Only the owner's plan matters: it sets how many co-authors the book can have, and AI runs only ever use the owner's allowance.
What can a co-author see?
Only the books you've invited them to: the manuscript, version history, comments, story bible, plans, notes, revision desk and saved views of that book, plus the results of story scans you've already run. Your other books, your settings, reading links and billing stay invisible to them. They see your name; only the owner sees co-authors' email addresses.
Who can run a story scan or ask a question?
Only the owner. AI runs use the owner's allowance and need the owner's permission for that book, so they stay in the owner's hands. A co-author can read and act on the findings of scans the owner has run.
What happens if I remove a co-author?
They lose access to the book straight away. What they wrote stays in the book, and its history still shows who saved each version.
Can I co-write a series?
Invitations are per book, so invite your co-author to each book you'd like to share.
Try co-authoring on your own draft
Import your draft from Word, Scrivener, RTF, EPUB or Markdown, or start on a blank page. The 14-day trial needs no card, and your book is exportable from the first word.
