Imagine if your next novel could be publish-ready 10x faster! Instead of taking three long years of everyday writing, it would only take 3 to 4 months from start to end. This is totally possible in 2024 when you have a good AI book-writing software tool acting as your most devoted brainstorming partner!
The AI revolution has extended its reach into the realm of literature, and it’s here to be your collaborator, not your competitor.
You might think that artificial intelligence is mostly used in business, but with the enormous progress boost that the tech market encountered thanks to the explosive interest in ChatGPT, AI in book writing is no more a thing of the future.
In fact, there are already some cases of fictional books published with heavy AI assistance, such as “Death of an Author” by Stephen Marche. The book was called “an exciting read” and “the best example yet of the great writing that can be done with an LLM like ChatGPT” in a book review on Wired.
In this article, we’ll explore the top 7 epic AI fiction book writing software tools of 2024 that are redefining the boundaries of storytelling. We’ll look at how you can step up your book-writing skills with AI’s help and dig into what AI tools can do for you besides the writing itself.
This guide is for fiction book writers, novelists, and editors. If you need to create an ebook freebie or a non-fiction book, you might want to look at my list of the best ebook generators instead.
Can AI write good fiction?
Artificial intelligence can potentially write good-quality fiction books, but only if you give it proper guidance every step of the way. While AI can generate ideas and string together words, the heart of the story – its soul and essence – still comes from the human author.
AI tools for book writing are designed to supercharge your creativity, assisting you in everything from character development to plot creation, all while ensuring your unique voice and style remain the focal point.
In a way, it’s akin to having a co-author who never sleeps and is always ready to provide a fresh twist or an unexpected subplot, while still supporting and enhancing your every idea. With an AI writing tool at your service, you can forget about writer’s block and never stare at a blank page again!
What makes a good AI fiction book writing tool?
So, what does it take for an AI book writing software to claim the title of “the best”?
It’s a complex recipe, blending innovative technology with intuitive design, all the while ensuring it becomes a seamless extension of your creative process.
As I’m writing this, there are 5k+ AI tools already available on the market, a considerable chunk of which are AI writers. And hundreds more are launched every month. But, to be honest, many of them aren’t good quality and certainly aren’t usable for fiction writing.
Most AI writing tools are created with marketing goals in mind, and even those that excel at social media post creation or long-form website content generation, are subpar when it comes to writing a book.
A modern blog article has nothing in common with a fiction book (well, maybe a few words). For the latter, you need compelling characters, a well-crafted plot, immersive storytelling, an engaging flow, and a satisfying resolution that makes sense.
The best AI tool for fiction writers is not a general AI writer that can write everything on earth. The best tool is the one that is designed with novel writing in mind and trained on actual examples of good fiction and not just news content from the internet.
And this is exactly what’s on our list today.
What is the best AI book writing software?
According to my extensive research and hands-on testing of various tools, here are the top seven AI book writing software tools for fiction writers in 2024:
1. Sudowrite
Best AI tool for creative writing
Sudowrite is a forward-thinking AI fiction writing assistant designed to enrich the creative process for novelists.
Combining the relaxed charm of a friendly co-writer with the precision of technology, it’s a comprehensive AI book writer that is way ahead of any other similar tool on the market.
It helps with common writing problems, assisting in story development and maintaining a good pace. It also encourages creative thinking and imaginative brainstorming.
With its ‘Expand’ feature, Sudowrite attends to pacing issues in your story, meticulously building out scenes that might feel rushed, ensuring a balanced narrative that keeps your readers captivated.
The ‘Write’ function, much like a turbo-charged autocomplete, steps in when words evade you, generating the next 300 words in your unique voice. It truly transforms the act of writing into an engaging and less daunting process.
Best Features of Sudowrite
Pricing
Sudowrite has three pricing plans: Hobby & Student gives you 30k AI-generated words for $10 a month, Professional is now 90k words for $25, and the Max plan can generate 300k words for $100.
There is a free 3-day trial to test Sudowrite’s capabilities, and it doesn’t even ask for your credit card info. They also offer an easy cancelation policy in case you aren’t impressed by the tool.
What makes Sudowrite unique is that it acts both as a partner who provides feedback on your writing and as a companion for brainstorming ideas. It’s there for you when you feel stuck in your creative process, and it’s always ready to help you transform your ideas into words. Definitely worth a try if you are a fiction writer!
2. Jasper AI
Best AI writing tool for writer’s block
While not initially designed for fiction writing, Jasper AI has the power to elevate your storytelling game to a whole new level.
You can give it a piece of your writing to analyze and it will aim to write in your voice. (They call it “brand voice” and while no tool can write exactly like you, it’s actually the most accurate I’ve ever seen.)
Marrying the intuitive guidance of a seasoned editor with the capabilities of cutting-edge artificial intelligence, it quickly joined the ranks of the best AI book writing software, redefining the landscape of AI-assisted fiction writing.
Known for AI generation skills even before ChatGPT became popular, Jasper is an intelligent co-writing tool that understands not just words but the context and sentiment behind them.
Confronted with the all-too-familiar blinking cursor? Jasper’s ‘Continue writing’ button is your immediate escape route. One click – and the tool continues in your own voice, helping you move forward whenever you get stuck.
It interprets the text that appears before the cursor, including any titles or background information, to produce context-aware and voice-consistent prose.
But it’s not just the technology that’s cutting-edge. The interface has been thoughtfully designed to encourage creative flow. It feels like a blank canvas, uncluttered and distraction-free, with a sidebar containing all the tools you need.
Best Features of Jasper
Pricing
Jasper offers a 7-day free trial, so you can try it yourself before committing.
The plan that will suit most book writers is called Creator and costs $49/month.
There is also a Pro plan that has a bunch of additional marketing tools and access to AI art to illustrate your book.
If you choose to pay annually, you get a sweet discount, about 20%.
3. Simplified
Best free AI book writing software
Simplified is an AI-powered book writing platform that is equally helpful for novice and seasoned writers. It offers a robust suite of features tailored for long-form content, such as novels and ebooks, in addition to a myriad of other content types like blogs and social media posts.
The platform makes your transition from the first draft to a polished manuscript both quick and efficient.
At the core of the Simplified AI tool are two features: Long-Form Writer and Short-Form Assistant, which cover various aspects of book writing. You can use them for outlining your novel, expanding or rewriting sentences, generating detailed character descriptions, and so much more!
What used to take hours and build up frustration (’cause you can’t think of the right word or an immersive enough scene setting) is now literally Simplified and only takes a few minutes with an AI writing assistant at your service.
Simplified offers an easy process for AI generation: just choose one of the templates, pick the target language, fill in some details about your story, and click Generate.
If you don’t like the initial result, the platform allows you to keep regenerating content until you get the desired output that suits your vision.
If you happen to co-write your book with another person, Simplified offers an array of tools that allow you to interact with each other and collaborate on the project.
Best Features of Simplified
Pricing
Simplified offers a solid Free Forever plan that lets you generate up to 2,000 words every month. This might be enough to understand the tool’s potential or if you only use it to write short stories.
The paid Simplified plan has dynamic pricing based on the volume of AI generations you need, starting at $18 per month for 35,000 words.
AI Writer Pro plan offers a 14-day free trial to explore all the features and understand how many words you really need before subscribing.
You also save 35% if you pay for Simplified AI Writer annually.
Whether you’re battling creative burnout or simply need a robust AI fiction writing assistant to simplify your creative process, Simplified is well-equipped to meet your diverse writing needs.
I like the ability to choose between long-form and short-form writer for different use cases, and that you can only pay for what you need.

Best AI creative writing generator for novelists
NovelAI is one of the most impressive AI tools for fiction writers. It offers a unique playground for constructing everything from intricate narratives to casual storytelling.
What sets NovelAI apart is its focus on delivering a personalized experience.
At the core of the platform are powerful artificial intelligence algorithms trained on real literature. These algorithms create human-like writing that seamlessly adapts to your own style and perspective.
NovelAI simplifies the creative process through its array of features. Key among them are the AI Modules, which allow you to emulate the styles of renowned writers like Arthur Conan Doyle and Edgar Allan Poe.

Best Features of NovelAI
Pricing
Novel AI offers a Free trial called Paper Tier that allows you to test the tool’s capabilities before choosing a paid tier. It gives you 50 free text generations without even creating an account and then 50 more when you sign up. The free trial doesn’t include the image generation tool.
All other tiers give you unlimited text generations and access to the AI image creator.
NovelAI has its own currency for calculating the AI training limitations and the number of AI image generations included in each tier. The cost ranges between $10-$25 per month.
Novel AI book writing software is a powerful extension of your creative thinking process. It is fun to use, especially the adventure module that allows you to co-create an ongoing story with the AI fiction writing assistant and see how it unravels!

The unlimited individual plan costs $20 per month or $16 if you pay annually.

If you care about the quality of your writing and want to make your story or novel the most amazing ever, I would encourage you to give the Business plan a try. The price varies depending on how much AI generation you need per month.

Best Features of Rytr
Pricing
Rytr has a generous Free Plan that allows you to generate with AI up to 10k characters and up to 5 images per month without paying anything at all. If you just need occasional support with your story development, you might not even need a paid plan!
There are two paid plans, and choosing the best one for you depends on the amount of AI generation you need per month.
As a single writer, you’ll probably never need more than the Saver plan (only $9/month) – it can generate up to 100k characters and 20 images every month, which is probably enough for writing a fiction book.
The Unlimited plan costs $29/month, gives you unlimited access to the AI writing tool, and only limits you to 100 images per month.
While Rytr will not write the whole book with you like Sudowrite or Jasper would, it is still a good fiction writing assistant. It can help you generate story plots, come up with fresh ideas, generate AI images to complement your storyline, expand or shorten your text, or even write a unique poem!
7. Character.ai
Best AI tool for writing book characters
Character AI is advanced AI software designed for writers, game developers, and creatives who want to breathe life into their characters.
With a focus on dynamic character development, the platform provides an arsenal of features that make it a one-stop solution for generating rich and believable personalities for any narrative.
One great use for the platform is to create a specific character that is part of your book and interact with it through the chat.
This will help you better understand the behavior and motives behind your character’s actions and even come up with more realistic dialog lines. This tool is especially useful for villains or other characters who are nothing like you and have to think differently.
At the heart of Character.AI are specialized algorithms that assist in crafting multi-dimensional characters. The AI tool offers a host of attributes to choose from, allowing you to define characters’ appearances, traits, motivations, and even their backstories. This way, you’re not just creating characters; you’re building complex individuals that will engage and captivate your audience in a relatable way.
Pricing
Character.ai is currently in beta and free to use, so go play with it while you can! I suspect they’ll introduce some kind of a paid subscription plan as soon as they are out of beta.
Your AI book is written: What’s next?
Let’s imagine that you already found the best AI book writing tool and finally finished the first draft. Congratulations! However, your journey doesn’t end here.
Your draft is a diamond in the rough, and now it’s time to refine it, make it pretty, and spread the word so people all over the world will actually read and enjoy it. That’s the end game, isn’t it?
Here are the next steps to transform your AI-assisted manuscript into a polished book everyone is excited to read!
Edit your book with ProWritingAid
Once your draft is complete, the first logical step is editing. This is where ProWritingAid comes into play. This AI-driven tool offers a plethora of features that go beyond basic grammar checks.
It has a built-in writing coach that analyzes your writing for coherence, style, and even emotional impact. ProWritingAid provides actionable advice to enhance your sentences, optimize paragraph flow, and improve readability.
With this tool, you can elevate the quality of your writing even if you choose to self-publish and don’t get to work with an editor.
ProWritingAid’s advanced analytics gets into the nitty-gritty of your narrative: it offers insights into overused words, vague language, and even sentence length variety. An indispensable thing for perfecting your book before showing it to your readers!
Triple-check for mistakes with Grammarly
Believe it or not, even seasoned writers miss errors on the first, second, or even third pass. Grammarly offers an additional layer of scrutiny that ensures your manuscript is free from pesky grammatical errors, awkward phrasing, or confusing sentences.
I’m using Grammarly for all my writing, and it’s like having a set of fresh eyes able to see all the little sneaky mistakes and typos that my brain tends to miss.
I also encourage you to take advantage of Grammarly’s plagiarism checker to make sure you didn’t accidentally get too inspired by someone else’s writing.
Think of Grammarly as your final line of defense. Before you publish, let this AI tool scan your manuscript for anything you might have missed. Whether it’s a misplaced comma, a subtle tense shift, or a poorly constructed sentence, Grammarly will catch it.
It’s your last chance to polish your book to perfection, so take advantage of it. Even the free plan is super powerful, not to mention the AI capabilities!
Create a beautiful cover with an AI
Now, let’s talk presentation. The phrase “don’t judge a book by its cover” doesn’t really apply in the publishing world. Everyone does that! I myself am guilty of buying my fair share of books just because they had pretty and intriguing covers.
A compelling cover is essential for capturing potential readers’ attention. Using a good AI book cover generator, you can create visually stunning and genre-appropriate covers without needing a degree in graphic design.
These AI tools offer a range of customization options, allowing you to match your cover with the book’s theme, tone, and content.
And the best part? It only takes a few minutes, and with thousands of templates, you don’t need to hire an expensive designer to make your book look beautiful and professional!
Spread the word about your book
After all the hard work, it’s time to share your masterpiece with the world. Jasper and various other AI writing tools can help you write engaging ads and descriptions to spread the word about your book online.
You can take advantage of AdCreative to quickly craft engaging social media posts for various platforms and use AI email assistants to generate compelling newsletters. These tools can help you get the word out effectively, reaching your target audience without breaking a sweat.
Turn your awesome book into an audiobook
With the rising popularity of audiobooks, you might consider converting your written words into spoken form. Thankfully, these days you don’t have to narrate the book yourself if you don’t want to – AI tools are getting surprisingly good at this!
For example, the Speechify voiceover tool is perfect for this transition. Known for its natural-sounding AI voices, Speechify can read your book aloud, turning it into an audiobook with ease.
Not only does this broaden your book’s accessibility, but it also taps into a wide market of listeners who prefer audiobooks over traditional reading. You’ve already got a compelling story; now give it a voice!
What AI book writing tools are, and what they aren’t
AI fiction writing tools are incredibly potent allies in the writing process. They can generate ideas, help with sentence structure, and even provide frameworks for plot development.
These AI systems are designed to assist you, the author, in navigating the often cumbersome and intricate phases of storytelling. They can take your initial ideas and turn them into compelling narrative structures, generate dialogue, assist in character development, and even suggest themes or subplots.
However, it’s crucial to remember that while AI can assist in the writing process, it can’t replace the unique creativity and emotional nuance that a human writer brings to a story.
The technology may be advanced, but it lacks the capacity to truly understand human emotions, subtleties, and the deeper elements that make a story resonate with readers.
In other words, an AI fiction writer can’t produce a page-turner by itself – but it can definitely help you do it. Use it wisely to augment your own skills, and the results can be extraordinary!
Benefits of using AI tools for book writing
Using AI tools for book writing can make life so much easier for fiction writers!
It offers a range of benefits designed to simplify the writing process, enhance your creativity, and elevate the quality of your work.
Here are the top benefits of using AI book writing tools:
- Time savings: An AI book writer can quickly generate text based on your guidelines, allowing you to complete chapters and scenes much faster than writing everything from scratch.
- Overcoming blank page syndrome: AI can generate prompts or even initial paragraphs, giving you a starting point when you’re staring at a blank page, unsure of how to begin.
- Completing your thoughts: Ever get halfway through a sentence and then get stuck? AI fiction writers can help by completing your sentence in a coherent and often surprisingly creative way.
- Generating detailed descriptions: When you’re struggling to paint a vivid picture, AI tools can help by offering detailed and engaging descriptions for settings, characters, and more.
- Finding perfect words and synonyms: If you’re looking for just the right word, an AI fiction writing assistant can suggest synonyms and alternative phrases to capture exactly what you’re trying to say.
- Generating unique names and creative story plots: AI can generate unique character names and offer story plots that you might not have thought of, adding layers of creativity and intrigue to your writing.
- Enhancing productivity: With the help of AI, you can spend more time developing the creative aspects of your book instead of typing words, while letting the tool handle the more mechanical elements like grammar and sentence structure.
AI book writing FAQs
AI book writing software is an online tool powered by artificial intelligence, designed to assist in the novel writing process. These tools can generate text in your voice and style, eliminate writer’s block, co-create characters and surrounding scenes with you, and help you in various stages of book development.
An AI generator can write fiction by using machine learning algorithms trained on large datasets of text, including novels, stories, and other forms of fiction.
Based on the input or prompt given, the AI can produce narrative structures, dialogues, descriptions, and more. It can follow general plot lines and even introduce twists, though the quality can vary and requires human oversight for refinement.
The likelihood of AI replacing fiction writers is low. While AI tools can assist in the fiction writing process, they lack the emotional intelligence, intricate understanding of human behavior, and creative flair that a human writer brings to storytelling. AI can be a valuable assistant, but the nuanced creativity needed in fiction writing is irreplaceable by current technology.
The ethics of using AI in fiction writing is generally considered acceptable as long as you use a hands-on approach for book writing, edit the outputs, and use AI as a tool to assist you in various stages and not just generate full books.
Like any other writing tool, it should respect copyright laws and not plagiarize content. I think that AI book writers can actually enrich the creative process by enabling authors to produce work more efficiently while still maintaining artistic integrity.
Final thoughts on writing books with AI
I hope you’re as excited as I am about the possibilities that these AI tools bring to the world of fiction writing!
This guide should’ve given you a solid understanding of AI’s impact on book writing and opened your eyes to the myriad of ways you can enhance your own storytelling.
