# Best AI for Novel Writing: 5 Tools for Novelists Compared

_Published: October 20, 2026_

> The 5 best AI tools for novelists, compared by stage: plotting, drafting, line editing, and manuscript feedback. Pricing, pros, cons, and who each fits.

Short answer: the best AI for novel writing depends on which part of the book you're stuck on. Novelcrafter is the strongest for planning and keeping a story bible, Sudowrite is the best at generating fiction prose, Claude is the most flexible brainstorming partner, ProWritingAid catches style patterns across a long draft, and Revise is the one I'd pick for editing a finished draft without losing your voice.

I compared these five tools on the jobs novelists actually hand to AI: outlining, drafting scenes, keeping characters consistent, line editing, and getting whole-manuscript feedback. I also looked closely at the thing most writers worry about: how much control you keep over your own sentences.

Here's the quick version:

- Use Novelcrafter if you plan your books and want AI tied to your outline, characters, and world notes

- Use Sudowrite if you want AI to draft or expand scenes in a fiction-tuned style

- Use Claude to talk through plot problems, motivations, and structure

- Use ProWritingAid for repeated words, pacing reports, and style checks across chapters

- Use Revise for line editing and story feedback where every change is a tracked edit you accept or reject

The main point: no single tool covers the whole process well. Most novelists end up with one tool for the messy front half (ideas and drafting) and one for the back half (revision and polish).

## 1. Revise

Revise, an AI book editor for novelists that edits with tracked changes

Revise is an AI editor, not an AI ghostwriter. You bring a chapter or a full manuscript (pasted, or copied in from Scrivener, Google Docs, or Word), and it suggests edits for clarity, dialogue, pacing, and word choice. Every suggestion shows up as a tracked change you can accept, reject, or modify, so nothing in your draft changes without you seeing it.

That matters more for fiction than for almost any other kind of writing. Novelists break grammar rules on purpose: fragments, run-ons in a panicked scene, dialect in dialogue. A tool that silently "fixes" those flattens the book.

### Line Editing That Keeps Your Voice

The line editor works sentence by sentence. You can turn on teaching mode to see why each edit was suggested, which is useful when you're trying to learn what's actually weak in your prose versus what's just a style choice. You can also personalize Revise to match your writing voice and set your own rules, such as "don't touch dialogue" or "keep British spelling."

If you want something bigger than a line edit, the chat reads the surrounding pages and makes changes in place. Ask it to tighten a scene or rework a line of dialogue, and the result comes back as suggestions you review like any other edit.

### Whole-Manuscript Feedback

Revise's Feedback reports read your full document and write a report without changing your draft:

- Story Critique: point of view, character list, outline, the protagonist's arc, what's working, and where to focus your revision

- Plot Analysis: an engagement score from 0 to 100, an engagement curve that flags slow sections, and craft scores per section

- Virtual Beta Reader: a first-person response from 20 composite fiction readers, with a verdict and highlights tied to the text

This is the kind of feedback you'd normally wait weeks for from beta readers. It doesn't replace them, but it lets you fix the obvious problems before you send the draft out.

### Pricing and Practical Use

- Free: 2,000 words per month and 1 Feedback report

- Pro: $16/month, or $8/month billed yearly. 400,000 words per month and 15 Feedback reports

- Ultra: $32/month, or $16/month billed yearly. 2,000,000 words per month, 40 Feedback reports, and Claude Opus 5.5

Revise works in over 40 languages, and your manuscript isn't used to train models. The honest limit: Revise won't brainstorm your plot from scratch or write chapter three for you. It's for the stage where the words exist and need to get better.

## 2. Sudowrite

Sudowrite homepage, an AI writing tool built for fiction

Sudowrite is the best-known AI tool built only for fiction. Its core tools (Write, Rewrite, Describe, and Expand) work inside your draft, and it uses its own fiction-focused models, Muse and Ballad, alongside more than 30 other models.

### Drafting and Expanding Scenes

Sudowrite is strongest when you know what happens in a scene but can't get the words moving. You can expand a thin paragraph, ask for sensory description, or generate a rough version of a scene from your notes. It can also match your writing style and track continuity across a series, which helps it avoid the generic tone you get from a general chatbot.

Higher plans add developmental edits, line edits, and beta reads, so Sudowrite now overlaps with editing tools too. Its center of gravity is still generation, though.

### Pricing and Credits

Sudowrite runs on credits, and every plan gets every feature. You're only choosing how much you can use:

- Hobby &#x26; Student: from $10/month (billed yearly), 225,000 credits

- Professional: from $22/month (billed yearly)

- Max: from $44/month (billed yearly), 2,000,000 credits that roll over for 12 months

There's a free trial with no credit card, but no ongoing free plan. The tradeoff: generated prose is a starting point. If you lean on it heavily, expect to revise it hard so the book sounds like you.

## 3. Novelcrafter

Novelcrafter homepage, novel writing software with an AI-connected story bible

Novelcrafter is a novel-writing app first and an AI tool second. Its centerpiece is the Codex, a story bible where you track characters, locations, lore, and relationships. The AI features use that Codex as context, so when you generate or rework a scene, it knows who your characters are.

### Planning, Outlining, and the Codex

If you're a plotter, this is the most natural fit on the list. You build your outline as acts, chapters, and scene beats, then use AI to generate prose from scene beats, summarize scenes, or extract characters from text you've already written. Workshop Chat (on the Artisan plan) lets you talk through scenes with that story context loaded.

### Bring Your Own AI Key

Novelcrafter doesn't sell AI credits. You connect your own AI provider account and pay for usage there, on top of the subscription. That gives you more control over which model you use, but it adds a setup step and a second bill.

- Scribe: $4/month, no AI

- Hobbyist: $8/month, adds AI with your own key

- Artisan: $14/month, adds chat features

- Specialist: $20/month, adds collaboration and teams

There's a 21-day free trial with no credit card, and no free plan.

## 4. ProWritingAid

ProWritingAid homepage showing Chapter Critique, Plot Analysis, and Virtual Beta Reader

ProWritingAid has been a novelist favorite for years because of its reports: overused words, sentence length variety, pacing, dialogue tags, sticky sentences, and more. It now adds AI features on top, including Chapter Critique and story analysis tools.

### Style Reports Across a Long Draft

The reports are where ProWritingAid earns its place. Run the overused words report on a 90,000-word draft and you'll find the crutch words you can't see anymore. You can also compare your writing style against 90 fiction authors and set up a custom style guide for character names and spellings.

The downside is noise. Fiction triggers a lot of flags that aren't real problems, so you need to know when to ignore it. For a deeper look at that tradeoff, see our comparison of revision tools tested on a real manuscript.

### Pricing and Story Credits

- Free: limited to 500 words at a time

- Premium: $30/month, or $10/month billed yearly ($120)

- Premium Pro: $36/month, or $12/month billed yearly ($144), with more chapter critiques plus live workshops

- Lifetime: $399 (Premium) or $699 (Premium Pro)

Whole-manuscript tools like Manuscript Analysis and Virtual Beta Reader run on separately purchased Story Credits, so check that cost if feedback on the full book is what you're after.

## 5. Claude

Claude homepage, a general AI assistant novelists use for brainstorming

Claude isn't a writing app. It's a general AI assistant, but it's one of the best for the thinking side of novel writing. It handles long pasted chapters well and tends to give more careful, less generic feedback on character and structure than most chatbots.

### Brainstorming and Plot Problem-Solving

Use it the way you'd use a smart friend who has read your outline:

- "My midpoint twist feels unearned. Here's the setup in chapters 4 to 9. What's missing?"

- "List five reasons this antagonist would wait instead of acting now."

- "Here's my synopsis. Where does the stakes curve go flat?"

Projects let you keep your outline, character notes, and chapters in one place so you don't paste them in every time.

### Where It Falls Short

There's no manuscript workflow: no tracked changes, no story bible, no chapter view. If you ask it to "edit" a chapter, it hands back a rewritten version, and it's on you to compare it line by line. Use it to think, then make the changes yourself or in an editing tool.

- Free: $0, with usage limits

- Pro: $17/month billed yearly, or $20 monthly

- Max: from $100/month for heavy use

## Use-Case Recommendations and Pros/Cons

If you're a plotter starting a new book, use Novelcrafter for the outline and Codex, plus Claude to pressure-test the plot.

If you're stuck mid-draft, Sudowrite is the fastest way to get words on the page. Treat its output as clay, not a finished scene.

If you've finished a draft, start with Revise's Plot Analysis or Virtual Beta Reader to find the big problems, then line edit chapter by chapter with tracked changes. Use ProWritingAid's reports to catch repetition at the end.

If you're on a tight budget, Revise, ProWritingAid, and Claude all have free plans. Pairing Claude for brainstorming with Revise for editing costs nothing to try.

## Final Verdict

If you want one tool for the whole job, you won't find it yet. The best AI for novel writing is a small stack: one tool to help you generate and plan, and one to help you revise.

For planning and drafting, Novelcrafter and Sudowrite lead. For revision, I'd choose Revise, because it works the way a good human editor does: it suggests changes, explains them if you ask, and leaves every final decision with you. Your book should still sound like you wrote it.

If you're at the editing stage now, you can try Revise free on a chapter. For the human side of that decision, read book editor vs. AI editing tool: which to use first.

## FAQs

### What is the best AI for novel writing?

It depends on the stage. Novelcrafter is best for planning with a story bible, Sudowrite for drafting and expanding scenes, and Revise for editing a finished draft while keeping your voice. Claude is a strong general option for brainstorming plot and character problems.

### What is the best free AI for novel writing?

Revise, ProWritingAid, and Claude all have free plans. Claude's free plan works well for brainstorming, and Revise's free plan includes 2,000 words of editing per month plus one full-manuscript Feedback report. Sudowrite and Novelcrafter offer free trials but no ongoing free plan.

### Is Sudowrite free?

No. Sudowrite offers a free trial with no credit card required, but there's no free plan. Paid plans start at $10/month billed yearly, and all plans include every feature. They differ only in monthly credits.

### What's a good Sudowrite alternative?

If you want planning and a story bible, Novelcrafter is the closest alternative. If you mainly want help improving prose you've already written, Revise is a better fit, since it edits with tracked changes instead of generating new text. For free brainstorming, Claude works well.

### Novelcrafter vs. Sudowrite: which is better?

Novelcrafter is better for plotters who want their outline, characters, and world notes to drive the AI. You bring your own AI key and pay for usage separately. Sudowrite is better if you want strong fiction prose generation out of the box with no setup, priced by credits.

### Will using AI make my novel sound generic?

It can, if AI writes most of the text. The safest approach is to use AI for ideas, feedback, and suggested edits you review one by one, rather than accepting full rewrites. Tools with tracked changes make it easier to keep only the edits that sound like you.
