Tabularia compared with Sudowrite

Two ways to get a model into your book

Sudowrite calls itself an AI writing partner for fiction. Its Story Bible carries an idea through an outline and into chapters, and tools such as Write and Expand suggest the next stretch of prose or fill in what a passage is missing. All of it runs on models Sudowrite selects and pays for on your behalf.

Tabularia arrives at the same help from the other end. It has no model of its own and does not sell you one — it has a connector, which points an assistant you already pay for at your manuscript. That assistant can read the book, search it, count it and answer questions about it, and it can write: a tightened sentence, a corrected name, a chapter drafted in the conversation. Left to itself, it puts everything it writes in a Draft named for it, such as Edits from Claude, and you merge what you want a difference at a time; it writes into your own pages only when you say so.

So the difference is not that one has AI and the other does not. It is who supplies the model, and who decides how much of it you get to use.

Who meters the model

Sudowrite bundles the models and meters them. Above the subscription, most AI actions spend credits, and credits do not convert to words at a fixed rate: by Sudowrite's own account the same allowance covers an order of magnitude more writing for one writer than another, depending on which features and which model they use. On the lower plans unused credits expire at the end of the month, and when they run out you buy more to keep going.

Tabularia has nothing to meter, because it is not the one buying the model. If you already subscribe to Claude or ChatGPT, that subscription is the whole allowance, and it is the assistant you have chosen rather than the one you were given. The connector is part of Tabularia's Cloud subscription, which also buys backup, sync, and sharing for review. Generation is not on the bill, so there is no second meter and nothing to top up mid-chapter.

That also means the model is yours to change. A better one arrives and you use it the day you switch assistants, without waiting for it to be added here.

The room around the writing

What Tabularia spends its own attention on is the manuscript, and what it carries is built for the second pass rather than the first: one typeset composition you can hold the shape of at length, timelines fastened to the passages that carry them, and drafts you branch and merge a difference at a time or all at once. Revision is the center of the application rather than a feature beside the editor, because a book is rewritten many more times than it is drafted.

Accepting and rejecting stay yours throughout. An assistant here cannot merge a Draft or accept a suggestion — its own or a collaborator’s — and cannot delete a Chapter, a Draft, or a Project. Tabularia never sends your work to an AI provider of its own; whether the assistant you connect keeps or trains on what it reads is a setting in that assistant, which is where you control it.

Why to switch

Sudowrite hands you a working setup, with its own fiction models and a menu of others to pick from, craft tools built around them, and generation tuned for fiction rather than general-purpose text.

Switch if you would rather bring the assistant you already pay for than rent a second one by the credit. What you get around it is a manuscript you can find your way through at any length. The Outline and Minimap take you anywhere in the book in a click, and Sheets keep the facts your assistant and you both check in one panel beside the page. A story shape gives the plan a place in the manuscript before any prose arrives, generated or not. And the page is typeset as a book from the first sentence.

They are not mutually exclusive, and a writer who drafts with help still has to revise. If you use both, prose arrives here in Markdown, plain text or DOCX and becomes a structured manuscript.

Bringing Sudowrite projects across

From the project card's ••• menu, Export as 1 doc merges every document in sidebar order into one Word file. That is the one to import.

Project export leaves out the Story Bible. Its Outline, Characters, and Worldbuilding sections each export separately as CSV. Nothing reads those files automatically, but its characters and settings make a quick start on Sheets.
