Table of contents

Our team has always believed in critical and creative thinking, which means we won't promise AI writing software that does all the work for you. 

Instead, this blog post offers a curated list of the best AI book writing tools designed to streamline the publishing process while ensuring the high quality your readers expect (and deserve).

We'll dive into all the pros and cons of each AI writing assistant, discuss their pricing, and highlight key features that are particularly useful for self-publishers. Plus, we'll share some exciting updates from that you won't want to miss!

By the way, here’s a little math equation for you:
AI + Amazon = Recurring Income (Even During Retirement)

If you want to discover how to publish books on Amazon using AI to earn virtually passive income, sign up for our free webinar. We'll show you our proven process that students around the glove have seen results like adding an extra $500 to even $10,000 a month in extra cash. See for yourself @ our no-cost publishing training that explains it all!

Is There an AI That Can Write a Book?

AI writing assistants like ChatGPT can aid in tasks like outlining, research, manuscript drafting, and other content generation, which isn't necessarily the same thing as producing a book at the click of a button, but these tasks alone can cut the publishing process in at least half. We're talking about going from everything taking months or years to just a matter of weeks!

So, indirectly, yes! AI can write a book and even a high-quality one, as long as you don’t outsource all of the critical and creative thinking. 

What Are the Best AI Writers?

ChatGPT, Jasper,,, and Anthropic's Claude are just some of the top-performing AI writers out there right now, but they're only scratching the surface of the exploding AI market.

We’ll get more into those later, but for now, these are some features that the best AI writing software tools have in common:

1. Natural Language Processing Capabilities

Natural Language Processing (NLP) lets AI tools understand human language and semantics, which is how we normally talk to one another. This means you can interact with the models using plain language—no coding or engineering required!

2. Ease of Use

The best AI tools are user-friendly from the start and don't really require any special training to get started or produce good outputs. Yes, even if you don't consider yourself "good with tech."

Don’t get us wrong, practice definitely helps make you more comfortable with prompting, but you should be able to jump right in and get straight to work without having to learn an entirely new skill set. 

3. Integration with Other Tools

The best AI writers offer seamless integration with other software to maximize productivity. For example, tools like ChatGPT can now produce images by integrating with Dall-E and Canva, all from the same dashboard. 

#1 - Best AI Tool for Kindle Publishing is the world’s first smart software custom-built for digital publishers by digital publishers. We've taken hundreds of combined years of publishing experience and turned it into one simple dashboard for researching, outlining, drafting, and exporting full-length ready-to-edit manuscripts on Amazon's most profitable niches. 

Big picture? We’re working on creating the first one-stop shop for self-publishers who want to put out the best quality books on their own schedules and on their own terms, which will eventually include the entire span of the publishing process. That’s a BIG statement, but we’ve never shied away from big goals together as a team. You'll even find us featured in Forbes, Foundr, Entrepreneur, Inc., and more.

Here's a bit more about us:

Why You Should Try and a First Look at Reviews

Hiring a ghostwriter can be expensive—like thousands of dollars just for one book. Not to mention, a 30,000-word manuscript might take human writers months to complete, and then you'll still have to go through multiple rounds of revisions and formatting just to get your book published. Now, there's nothing wrong with this business model, and it works! But we're all about empowering self-publishers as much as possible, which means giving YOU all the tools you need to take on the process yourself. is like having a personal team of ghostwriters and virtual assistants ready to brainstorm, research, and draft around the clock, giving you more time and more money (the two necessary ingredients for any business to scale up).

Here's what our Beta users have to say:

How to Use

Everything takes place inside a single dashboard, and the best part is that the AI software will keep working for you even if you're busy with other tasks (or spending a day with your family away from your laptop). There's an easily accessible video tutorial that demos the whole software, but our Help team is also available to answer any questions that pop up. The prompts on the screen guide you through the ideation and drafting process step by step and save your progress to make things as smooth and easy as possible. 

What Can Do?

Our engineering team has a TON of ideas on deck that we can't quite share yet, but for now, our AI software nails these four things:

  1. Idea Generation
  2. Customer and Competitor Research
  3. Book Descriptions
  4. Optimized Book Outlines

How to Get First Access

At the time of writing this post, is only available to current students enrolled in our AIA program as a courtesy, so securing your spot ASAP is the only way to get first access. Beta spots are limited, though. Just a heads up. 

If you're curious to know more about how this whole AI-publishing thing works, we've got a totally free webinar that lays it all out, no risk, no commitment. 

#2 - ChatGPT: Best for Brainstorming

Major Features:

  • ChatGPT is probably the most versatile AI writing tool on this list. It can simulate conversations, answer questions, and provide ideas and explanations on just about anything you could imagine, AKA you can say goodbye to writer's block.

Price Point:

  • ChatGPT offers a free version and a premium account at $20/month which gets you access to the latest models, faster response times, and priority access to new features and improvements.


  • ChatGPT can generate impressively human-like text most of the time, but its responses can occasionally veer off-topic or become repetitive if you're not specific with your prompts and feedback.
  • ChatGPT was trained on data up to a certain knowledge cutoff date, so you'll have to fact-check its outputs, especially regarding recent events. Otherwise, it will usually “hallucinate” the information and confidently present it as fact, even if something never happened. 

Self-Publishing Utility:

  • ChatGPT is an awesome tool for self-publishers looking to flesh out their ideas at any stage of the publishing process. It can generate tons of creative content, including plot ideas, author bios, and even whole sections of text that can be refined and used as starter drafts.
  • ChatGPT can also engage in dialogue, which makes it a great AI writing tool for planning realistic interactions between fictional characters or for developing interview-style content for non-fiction books.

#3 - JasperAI: Best for Heavy Content Creation

Major Features:

  • JasperAI is another AI tool powered by advanced GPT-3 technology, which enables it to generate high-quality content like blog posts, persuasive ad copy, and professional emails that sound as close to natural as possible.

Price Point:

  • JasperAI’s pricing starts at $39 per month for the basic plan, and they do offer a 7-day free trial, so you can take it for a test spin before committing to it. 


  • The cost of JasperAI can be higher than some other AI writing tools, which may be a barrier for authors or publishers on a tight budget.
  • JasperAI's settings and features can be overwhelming and might involve a steep learning curve for those not accustomed to AI models.

Self-Publishing Utility:

  • JasperAI provides specialized templates for writing book descriptions, author bios, and marketing copy.
  • JasperAI can complete unfinished sentences, propose multiple content variations, and help structure complex articles.

#4 - CopyAI: Best for Marketing and Promotional Content

  • Major Features:
    • CopyAI is an AI-powered writing assistant designed specifically for marketers. It provides a user-friendly interface with tools tailored for crafting digital ad copy, engaging social media posts, and persuasive product descriptions.
    • The platform offers a variety of pre-built templates and frameworks that help users quickly produce creative outputs tailored to different marketing objectives and channels, including email marketing campaigns and e-commerce platforms.
  • Price Point:
    • CopyAI offers a very accessible free starter plan, and premium plans start at $36 per month.
  • Cons:
    • CopyAI is typically better at producing shorter content.
    • Natural language processing algorithms don't always produce the right outputs, and you might have to make some pretty hefty edits or tweak your prompts to ensure the end result sounds human.
  • Self-Publishing Utility:
    • CopyAI is particularly useful for generating catchy book blurbs, crafting promotional posts that spark interest on social media, and developing advertising campaigns that drive book sales.
    • CopyAI can also help authors and publishers create compelling call-to-actions (CTAs), like requesting readers to leave an honest review through the Kindle store. 

#5 - Claude: Best for Limited Requests

Major Features:

  • Claude is made up of a family of Large Learning Models that are trained on data different from ChatGPT, so they're likely to produce different outputs.
  • Anthropic says they prioritize factual accuracy and fairness in their training of the models, and this will remain their #1 priority as they grow. 

Price Point:

  • Claude offers a free plan and a $20/month premium plan, just like ChatGPT.


  • Claude access is currently limited as it’s also in its beta stage.
  • Based on initial feedback, it looks like Claude will produce less versatile outputs for certain creative or highly stylized content demands than other AI tools on the market, but they’re still working out the kinks in their beta version, so this may change. 

Self-Publishing Utility:

  • Claude is working to ensure that the content generated is ethically sound and free from problematic biases, which is a good thing for non-fiction publishers looking to build credibility and trust with their readers (especially if you’re dealing with sensitive or controversial topics).

#6 - Writesonic: Best for Fast Digital Marketing Content

Major Features:

  • Writesonic is tailored specifically for digital marketing, making it ideal for creating landing pages, persuasive ad copy, and other promotional content.
  • Beyond basic text generation, Writesonic can also produce blog outlines, product descriptions, and full-length articles, all designed to engage readers and improve search engine visibility.

Price Point:

  • Writesonic offers several individual plans ranging from $0/month to $16/month.


  • Although Writesonic is good at creating generic content, aligning the AI-generated output with a specific brand voice can be tricky.
  • Some users have said they don't think the platform produces creative enough outputs, which isn't ideal when the aim is to stand out in a crowded market.

Self-Publishing Utility:

  • Writesonic lets authors and publishers prepare a variety of promotional materials without needing deep marketing expertise.
  • Writesonic is an AI writing tool that can also analyze data, which can be helpful if you publish your books across several publishing platforms.

#7 - Sudowrite: Best Fiction Writing Tool

Major Features:

  • Sudowrite is an AI book writer tailored specifically for fiction writers that can help with brainstorming, rewriting, and polishing drafts, significantly speeding up the novel writing process. As far as creative writing goes, it can also offer suggestions for plot development, character development, and setting descriptions.
  • The AI tool can suggest ways to rewrite sentences or paragraphs to improve the overall flow. This can be especially helpful during the editing phase to enhance the overall quality of the manuscript.

Price Point:

  • Sudowrite's subscriptions start at $10 per month for writing novels.


  • Sudowrite excels in creative writing scenarios but isn't really designed to produce search-engine-optimized or fact-based content. This focus on fiction might limit its applicability for authors or self-publishers who also need to create promotional or non-fiction content as part of their work.
  • The AI’s creative suggestions may not always align perfectly with your vision, but you'll find that with most AI tools every now and then.

Self-Publishing Utility:

  • Sudowrite is by far the best AI fiction writer on the market.
  • It understands the unique parts of the fiction writing process, such as crafting a backstory, developing prose, and incorporating scene descriptions between dialogue.
  • Sudowrite also has a function for changing the pacing of a story or generating key narrative components at the click of a button.

#8 - Hemingway: Best for Checking Reading Difficulty

Major Features:

  • Hemingway focuses on refining and enhancing existing text to improve clarity.
  • It highlights dense and complex sentences, passive voice, adverbs, and other common issues that can cloud writing.
  • Hemingway also provides grade-level readability scores and offers suggestions to simplify language, which can be particularly useful for authors and publishers looking to make their writing more accessible to a broader audience.

Price Point:

  • Hemingway Editor offers a totally free version with paid plans starting at $10/month.


  • Unlike some AI writing assistants, Hemingway does not generate content from scratch. Instead, it focuses on improving text that has already been written. This limitation means that it's best used as a complementary tool alongside other AI writing tools that assist with initial content creation.
  • Some users might find its suggestions too rigid, potentially oversimplifying nuanced text or altering the author's intended voice.

Self-Publishing Utility:

  • Hemingway Editor is particularly useful for determining the grade level your competition is writing for and proofreading your manuscript before publication.

#9 - ProWritingAid: Best for Developmental Editing

Major Features:

  • ProWritingAid is a comprehensive AI writer that provides detailed reports and suggestions to improve clarity, style, grammar, and punctuation.
  • It also integrates with platforms like Microsoft Word, Google Docs, and Scrivener.

Price Point:

  • ProWritingAid offers a decent free subscription as well as premium subscriptions starting at $10/month (and they often have sales).


  • Some features can be overwhelming for new users, so there could be a bit of a learning curve.
  • The premium features require a subscription, which might not be feasible for everyone.

Self-Publishing Utility:

  • ProWritingAid helps ensure consistency in writing style and tone better than many other AI writing tools.
  • The style guide feature is particularly useful for authors and publishers who write series or multiple books in the same universe.
  • It will point out if there's a lot of repetition and offer better suggestions in their place.
  • It’s good for both fiction and non-fiction. 

#10 - Grammarly: Best for Proofreading

Major Features:

  • ProWritingAid and Grammarly are pretty comparable, but Grammarly is known as an advanced grammar tool that also checks for contextual spelling errors, punctuation, and style nuances.
  • Grammarly offers detailed explanations for each correction, helping writers and authors improve their skills.

Price Point:

  • There's a basic free plan available, as well as the option to upgrade to a pro plan at $12/month.


  • Grammarly doesn't offer as detailed analysis as ProWritingAid for certain types of writing.
  • You'll have to upgrade your account to access the style checker and plagiarism detector.

Self-Publishing Utility:

  • Grammarly is much cheaper than a professional editor.
  • The plagiarism detector will scan the web for matches, display the percentage, and link directly to the other sources so you can cross-reference your manuscript and make any necessary changes before publishing.

#11 - Midjourney: Best AI Image Generator

Major Features:

  • Midjourney is an AI image generator that specializes in creating high-quality, artistic images from textual descriptions in seconds. It excels at generating unique visual content that can be fine-tuned through user prompts or edited with other platforms like Canva.
  • Midjourney offers various styles and aesthetics, making it versatile for different book cover designs or promotional materials.

Price Point:

  • Midjourney offers a basic free trial with limited runs. Regular users' paid memberships start at $10/month, though the $30/month plan typically offers more bang for your buck.


  • The AI tool can produce unpredictable results if your prompts are not well specified.
  • The learning curve to effectively use the tool and craft detailed prompts that produce desired results might be a bit much at the start.

Self-Publishing Utility:

Self-Publishing Applications for AI Writing Software

AI writing software is all about making your life as a publisher easier by speeding up certain parts of the process, giving you the freedom and time to focus on the things that really matter. We've already mentioned a few ways they can help with the writing process, but here are some other ideas to get the most out of your book writing tool:

Book Content Creation

  • Drafting: Speed up the writing process by generating niche ideas, detailed chapter outlines, and segues between chapters.
  • Non-fiction Content: Produce well-researched, factual content for educational books or how-to guides.

Marketing and Promotion

  • Book Descriptions: Craft engaging and persuasive descriptions that captivate potential readers at first glance, and optimize your metadata to make your book more likely to appear in the searches. 
  • Press Releases: Automatically generate press releases to announce new publications or book signings.
  • Email Campaigns: Develop targeted email marketing campaigns to promote your book launches and author events or book bundles. 

Supplementary Content Generation

  • Related Blog Posts: Generate blog content that complements your book’s themes to draw in more readers.
  • Author Bios: Create polished and professional author bios for use on various platforms.
  • Reader Engagement Posts: Develop interactive content for social media to engage readers and maintain a vibrant online presence.
  • Reader Guides: Produce study guides or discussion questions that accompany educational texts or book club meetings.
  • Bonus Content: Generate additional chapters or exclusive content for special editions or reader incentives.
  • Kindle A+ Content: Plan text-driven or visually-driven content to make your book listing stand out on KDP and attract new readers.

Challenges and Limitations of AI Writing Software

While AI writing software offers significant time-saving benefits and generative capabilities, it can only take you 90% of the way there—It's still your job to cross the finish line.

Here's what some of the AI models might struggle with and what to look out for:

Understanding Context

Most novel writing software relies on pre-trained data, so if you input a topic related to a current event, the AI tool might fail to incorporate the most recent developments or nuances related to the topic.

Handling Nuances in Language

AI tends to struggle most with writing prompts related to the creative writing process and things like:

  • Idioms and colloquialisms: Phrases unique to certain cultures or languages might be misinterpreted.
  • Sarcasm and humor: Usually, it churns out really awkward or flat content.

You can try to give the models examples of the content you’re aiming for to help train them, but this doesn’t always work. 

Maintaining Originality

Because AI-generated content borrows bits and pieces from the millions of sources it has scanned, there is always a small chance that it may lack originality and creative flair in its output. AI tools function based on algorithms that detect patterns and generate content accordingly. 

This is why we tell our students to edit, edit, edit, and always add their personal touch, even if they like what the AI tool came up with.

Ethical Considerations with AI-Generated Content

This is the big elephant in the room, right? How to use AI in the most ethical way possible.

Here's the industry standard:

Transparency in Usage

You must disclose the use of AI in content creation according to the content guidelines set by many publishing platforms these days, even including Amazon's KDP.

This includes:

  • Purpose: Indicating whether AI was used for pure generation or as an assistant during drafting, researching, or editing.
  • Scope: Clarifying the extent to which AI contributed to the final output.

You can read more about how AI writing works here.

Content Authenticity

Authenticity involves maintaining the originality of your content.

You are responsible for:

  • Verification: Ensuring that AI-generated content is fact-checked.
  • Plagiarism: Avoiding the replication of existing content without appropriate attribution (for AI-generated words and images).

Predicting Future Trends in AI Writing

Listen, AI writing tools simply aren't going to go away. Not when Amazon, Google, Microsoft, and all the other big-name companies are pumping billions and billions of dollars into AI research. You have a big choice to make: Either get ahead of the curve or try to play catch-up three months from now when all your competitors are already lightyears ahead and making thousands of dollars more in royalties.

If you want to be in the first camp of publishers, these are the trends to look out for:

1. Predictive Writing

Your writing experience is set to become even faster and more intuitive as AI book writers get trained on even more data. Eventually, these writing tools will offer you real-time suggestions, complete your sentences, and help you construct more coherent paragraphs right in your manuscript doc.

  • Real-time Suggestions: Predictive text that anticipates your next words and phrases to speed up the writing process.
  • Sentence Completion: AI helps finish your thoughts, reducing typing fatigue and increasing efficiency.
  • Enhanced Coherence: AI tools analyze the context to ensure that additions are contextually appropriate.

2. Voice-Assisted Writing

ChatGPT recently unveiled voice commands for its premium subscribers. This will also become more and more commonplace among other AI writing tools.

Voice-assisted writing will enable you to compose text simply by speaking as AI develops a better grasp of natural language processing and understanding. This will streamline writing tasks and open doors for those with disabilities or those who prefer speech over typing. How cool is that?

  • Hands-free Writing: Dictate your content and have it transcribed accurately by sophisticated AI.
  • Accessibility Improvements: Makes writing more accessible to people with disabilities affecting their ability to type.
  • Natural Language Processing: Enhanced capabilities to understand and process human speech with higher accuracy.

3. Collaborative Writing Features

AI will likely enhance collaborative book writing features, making teamwork on documents a piece of cake, even if there are thousands of miles between you and your ghostwriter, designer, or other business partners. You'll see real-time edits, suggestions from AI based on each team member's style, and merging of content without conflicts.

  • Real-time Edits and Suggestions: Team members can see changes as they happen, with AI suggestions tailored to improve group coherence and style.
  • Conflict-Free Merging: AI helps integrate multiple edits smoothly, making the best use of everyone’s time. 

4. Personalization through AI

ChatGPT is already working on this, but there will be a day when your writing software will adapt to your unique writing style and preferences, offering tailored advice and outputs that are spot on more often than not. This extends to grammar assistance, vocabulary, and structure improvements, all customized to your specific publishing needs.

  • Style Adaptation: AI detects and learns your writing style, offering suggestions that maintain your voice.
  • Custom Grammar and Vocabulary Assistance: Provides advice suited to your typical word choice and sentence structure.
  • Document Structure Optimization: AI suggests improvements based on the type of document you are creating.
