Ellipsus is a collaborative writing tool built around drafts, comments, and working with other people.
Inkwell is a space built for the particular shape of a novel, written mostly alone.
Here is an honest look at where each one fits.
Best for writers who collaborate closely with co-authors, editors, or beta readers, and want the whole conversation in one place.
Best for writers who write mostly on their own and want their whole story, cast, world, and progress kept in one calm space.

Ellipsus solves a real problem. A lot of collaborative writing ends up spread across a shared document, a chat app, and a string of direct messages, and keeping track of which note belongs to which draft becomes its own small job. Ellipsus keeps drafts, comments, and real-time chat with your collaborators in one place, and its branching drafts let you try a new direction while keeping it linked back to the original, without duplicating the whole document by hand. For a novel written closely with co-authors or a small circle of beta readers, that is a genuinely useful design.
Where Ellipsus falls short is on the parts of a novel that live outside the multi-draft and co-author feedback loop. Its outline tool helps organize a manuscript, but there is no dedicated place for a cast of characters or the details of an invented world, and nothing built in to track a writing goal or a daily streak (although they do have a built in timer for sprints). That gap tends to show up in the long middle of a first draft, when a solo novelist is working alone with nothing yet ready to share.
Inkwell is built around the part of the process that comes first and lasts longest: figuring out who your characters are, what your world holds, and how the story is shaped, then sitting down to draft it, mostly by yourself. Your outline, your characters, and your lore live in the same space as the manuscript from the very beginning, so the groundwork you lay before you ever write a scene stays close at hand instead of living in a separate tool or a stack of notes.
That same space carries you through the long solitary stretch of drafting itself. Goals, milestones, and a calm view of your streaks help you keep showing up day after day, with no collaborator or open comment thread required to stay motivated. When a draft is finally ready, you can invite a reader in on your own timeline, but nothing about getting there depends on someone else being in the room.
Ellipsus does a few specific things very well.
Comments and real-time chat with your collaborators live alongside the draft itself, instead of scattered across other apps.
Try a new direction and keep it linked to the original, without copying the whole document to experiment.
Invite as many co-authors, editors, or beta readers as you want on the free tier.
A focused-writing timer lives right in the tool, so hitting a sprint goal does not require a separate app or a clock across the room.
Inkwell is built for the long stretch before there is a draft to share, as well as the stretch after.
Manuscript, outline, characters, and lore live together in one organized place, with real depth for the cast and world that a drafting-and-feedback tool does not cover.
Goals, milestones, and a calm view of your streaks and trends help you keep going, no co-author or open thread needed to stay on track.
Your work syncs automatically when you are online and stays with you when you are not, so a lost connection never costs you a writing session.
Invite a trusted reader to your draft and collect their notes right in the margin, against the exact lines they are responding to, whenever you choose to share it.
Its branching drafts and free tier for collaborators fit that kind of project well.
You can still easily invite readers in to provide in-line feedback when a draft is ready.
These tools solve two different problems: Ellipsus focuses on collaboration, while Inkwell focuses on the daily habit of writing, holding your characters, your world, and your notes together, and helping you finish the story.
