Ellipsus
Collaborative writing tool for creative writers
What is Ellipsus?
Ellipsus is a browser-based collaborative writing tool from Berlin-based Ellipsus GmbH, aimed at creative writers. A document can branch into linked drafts that are compared side by side and merged back, with comments, version history and sharing roles for co-authors, editors and beta readers. The company says it will never add generative AI or train models on users' work. The free plan has no document limits, and Plus is sold on a subscribe-to-own basis.
Ellipsus has a free plan. Paid plans start at $6 per month for 24 months, or $99 one-time. See every plan
Good for
- Co-authors, editors and beta readers working on fiction together
- Fan fiction writers who publish to AO3
- Writers who want a tool with no generative AI
- People who would sooner own a license than rent one
Worth knowing
- Browser-based only: there is no mobile or desktop app yet, though the help center suggests setting it up as a PWA.
- Offline access and tables are listed as still to come.
- On the free plan, version history covers 30 days and image uploads are capped at 512 KB.
- Collaborator chat is moving to Plus and becomes read-only for free users.
Key features
- Linked drafts
- A document can branch into as many drafts as needed for trying ideas or working with editors. Drafts stay linked to their document, so there are no separate files to manage.
- Compare and merge
- Drafts can be viewed side by side to check what changed, and the writer chooses which edits are merged into the main document.
- Collaboration and feedback
- Unlimited collaborators can write in the same draft, comment and react. Collaborator roles and share links control what each person can do.
- Version history
- Past versions of a piece can be viewed and restored: 30 days of history on the free plan, unlimited on Plus.
- Publishing and export
- Posts new works and chapters to AO3, exports PDF, HTML, Markdown and rich text, and creates reader links that can be opened without an account.
- Emboss and writing insights
- Plus adds shareable authorship badges, public version history and writing insights such as sentence length, passive voice and word frequency, computed on the device without AI.
