New Quest vs Sudowrite

Sudowrite is an AI writing tool for fiction, and the most polished one in the category. Its Story Bible walks you from an idea to an outline to chapter beats to drafted prose, and it sits at the series level rather than inside a single book. Muse 1.5, their own model, is fine-tuned on published fiction with the authors' consent, and it writes genre prose noticeably better out of the box than a general-purpose chat model. Chapter Continuity feeds prior narrative into generation for you. There is nothing to configure and no API key to find.

Sudowrite writes the prose, with about 20,000 words of prior narrative in view; New Quest writes nothing and keeps the whole record, for whichever model you already draft with.

The ledger

The same question, asked of both.

Can my LLM read this while I draft?
Sudowrite
No. There is no MCP endpoint, no public API and no way to bring your own model. The Story Bible works inside Sudowrite's editor, with Sudowrite's models.
New Quest
A hosted remote MCP server is the product. Claude, ChatGPT, Gemini and Cursor query the bible directly and write changes back to it.
Will it still know what happened in chapter 8 when I'm on chapter 96?
Sudowrite
Chapter Continuity feeds prior narrative into generation automatically, capped at roughly 20,000 words across up to 25 linked chapters. The Story Bible persists past that. The narrative window does not.
New Quest
Chapter 8 is a query, not a window. Every change is an event tied to a scene, so asking what a character knew at chapter 8 returns the record from chapter 8.
Can something write the prose when the page is blank?
Sudowrite
Yes, and this is what Sudowrite is for. Muse 1.5 drafts genre fiction well out of the box, with Describe, Expand, Rewrite and Feedback beside it, Canvas for plot and theme work, and over a thousand plugins.
New Quest
Nothing. New Quest contains zero text generation and never calls a model itself. Your model does the drafting, on your account, using the bible as its constraints.
Where does level 14 live, or 4,200 XP, or a skill tier?
Sudowrite
In prose. The Story Bible is written text rather than typed data, so numeric state is something you maintain by hand and nothing objects when it drifts.
New Quest
In typed fields. Stat blocks, levels, XP, skills, inventory and System state are structured records, and the whole layer is optional if you don't write LitRPG.
Does one bible cover the whole series, or just this book?
Sudowrite
The whole series. The Story Bible sits at the series level rather than inside a single book.
New Quest
The whole series. One world, every book.
What does this cost me, all in?
Sudowrite
On annual billing: Hobby and Student $10 a month with 225,000 credits, Professional $22 with 450,000, Max $44 with 2,000,000 that roll over for twelve months. Monthly billing runs roughly $19, $29 and $59. Every tier is the same features with a different credit allowance, and generation draws on it, so drafting and revising share one budget. The AI is included, so there is no second bill.
New Quest
Free for one book. $29 a month through the Guild, which includes the community, or $39 for the app alone. You bring your own model, so add whatever that already costs you.
How long before I'm actually writing?
Sudowrite
You sign in and go. No API key, no OpenRouter account, no MCP configuration, and the trial takes no card.
New Quest
Longer. The bible is worth nothing until you have built some of it, and connecting a model is a couple of minutes of setup after that.
Can I sweep the finished book for contradictions?
Sudowrite
Consistency is handled while you draft, by Chapter Continuity and the Story Bible feeding the model context. Sudowrite documents no separate pass over a finished manuscript.
New Quest
A continuity check that reads the whole book and never calls a model. Dead characters walking, spells nobody learned, HP over max. Same input, same answer, every time.

Choosing

One of these is probably you.

Choose Sudowrite if

Your bottleneck is 2,000 words today and a blank page, not a magic system your model keeps forgetting. Sudowrite is better at the blank page than we are. New Quest generates nothing at all.
You want it working today. No API key, no OpenRouter account, no MCP configuration, and a free trial that takes no card.
Muse 1.5 is fine-tuned on published fiction, with the authors' consent, and it writes genre prose better out of the box than a general-purpose model does.
$22 a month on annual billing covers the software and the AI together. One bill, no metered API key of your own to watch.

Go and look at Sudowrite →

Choose New Quest if

You already draft somewhere else, in Claude or ChatGPT or Cursor or Word, and you want the bible to be there with you rather than in one vendor's editor.
Your series is long enough that the detail which matters, a skill unlocked in chapter 8 or a debt owed since chapter 31, sits well outside any 20,000-word window.
You write progression fiction and the numbers have to be right. Levels, XP, skills and System state as typed data, not paragraphs you police yourself.
You want the continuity check to be arithmetic rather than a model's opinion. It never calls an AI, so it gives the same answer twice.
The manuscript needs to arrive from Word or Scrivener and leave as an EPUB, with a pronunciation guide for the narrator.
You want to try it on one book without paying anything, and to take the whole lot back out again whenever you like.

Questions

What people ask before switching.

Can I use both?

Yes, and plenty of people should. Draft in Sudowrite because Muse is good at it, then keep the canonical world in New Quest so it survives past the continuity window and stays readable by any other model you use. The honest catch is that the two won't talk to each other. Sudowrite has no public API, so anything that moves between them, you move.

How do I get my Story Bible across?

By hand, once. There is no export path we can automate, because Sudowrite publishes no API for us to read from. In practice it's a copy-and-paste session per character, location and rule. The manuscript is easier: paste your drafted chapters in and they land split into chapters and scenes.

Is New Quest actually more expensive?

If you don't already pay for an LLM, yes. Sudowrite's Professional is $22 a month on annual billing with the AI included; New Quest is $29 through the Guild or $39 for the app, and your model is on top of that. If you already pay $20 a month for Claude or ChatGPT for other reasons, the difference is $7 a month at the Guild tier and $17 at the app tier. If you don't, add the whole of your model's bill. The free tier is one book, which is the cheap way to find out which of those you are.

What happens to my world if I leave?

You export it. World data and manuscript both, and the whole book compiles to a single Markdown file. Delete means delete. We never train on your work and we never send it anywhere except the model you choose to connect, on your own account.

Will New Quest ever draft prose for me?

No. It's not a gap we're waiting to fill; it's the shape of the tool. New Quest holds what's true about your world and hands it to whatever model you write with. If you want the tool itself to write, Sudowrite already does that well and there's no reason for us to do it worse.
