Top 8 AI Book Generator Tools for Aspiring Writers in 2025

A writer knows the frustration of spending more time figuring out how to train AI than actually writing. That’s why we took the time to test the most popular AI story generators, evaluating each one for its storytelling features and the quality of its output.

AI has revolutionized traditional book writing, but how does it work? These AI book generators rely on natural language processing (NLP) and machine learning models trained on extensive datasets to produce coherent, contextually relevant text based on user input. 

With advanced AI models, these tools will help you overcome writer’s block, generate fresh ideas, or even create a complete book, transforming how stories are written.

This article explores the best AI story generators available today, highlighting their features, benefits, and how they enhance the art of storytelling. 

Top 10 AI Book Generators to Write Compelling Stories

Here is the list of top AI book generators to help you generate your books and novels:

1. AI Book Generator by Squibler for Full-Length Books

Squibler’s AI Book Generator is a tool designed to simplify and accelerate the writing process for authors at any stage. With this tool, you can generate complete book drafts by providing a brief idea or outline to the AI.

This AI story maker asks you to provide a summary to generate a full-length book from your idea. You also have the option to generate a book outline that you can expand on later. With the outline, you can organize your thoughts into cohesive chapters, ensuring a solid foundation for storytelling. 

You can write both fiction and nonfiction. For fiction, you can write romance, science, mystery, history, adventure, and more genres. 

For nonfiction, you can write self-help, sciences, health, business, and other related genres.

It creates structured content and offers AI-generated book covers during onboarding, giving each project a personalized touch. The generated books are segmented chapter by chapter for you to edit and customize the book once the book generator shares the first draft.  

Once you are satisfied with the AI-generated book, you can customize it in Squibler’s editor with your creative touch. Squibler offers editing software that allows you to format, write, rewrite, expand, and even produce graphics.

Squibler also provides a hard copy to users who have subscribed to the annual plan. You can fill out the printing form and you will receive one hardcover copy of your book to your address. That also includes the cover design.

Pricing: When it comes to pricing, there is a free and paid version of this AI book generator. You can try the free version with limited capabilities. For unlimited capabilities, it costs $192 (which is $16 per month) per year. If you choose to pay every month instead of yearly, it costs $29. 

2. AI Writing for Fiction by Sudowrite

Sudowrite excels in enhancing creative writing with its AI features. It helps simplify the writing process, making it especially valuable for fiction writers who need a creative boost or struggle with writer’s block. 

Its story engine guides you through writing a novel, and there are various brainstorming tools and options for editing your manuscript along the way. 

Sudowrite itself claims to be better for fiction writers, which is why it may not be the best solution for nonfiction writers. Moreover, you can also notice occasional repetition in suggestions, and generic and overly simplified story elements if you do not guide it with detailed prompts. 

Sudowrite is good for sparking ideas, the generated content requires significant refinements to match your unique voice and style. This makes it more suited as a collaborative tool rather than a standalone solution for creating a complete book.

Pricing: You can choose from three pricing plans i.e., $19, $29, and $59 per month based on your needs and budget. They offer some discounts if you purchase a yearly subscription.

3. AI Story Generator by Squibler to Create Stories

This AI Story Generator tool by Squibler offers an intuitive platform for you to craft full-length books. The interface is clean and simple, allows you to select a genre, adjust the creativity level from realistic to inventive, and input a basic story plot. You can write the story in love, fantasy, romance, horror, and other genres. 

This variety of options makes it more accessible for writers with varying levels of expertise and creativity. With the tool’s “Advanced Settings,” you can further enhance customization, and get solid control over the direction of your story, setting description, and characters.

However, while the generator provides a solid framework for story creation, you’d need to provide story descriptions and character details to tie elements together. 

If you are a professional looking to put in 20% of the effort, Squibler holds the capability to manage the remaining 80% of the work for writing a book.

Pricing: You can purchase the AI writing software with an annual subscription for $192 collectively (which is $16 a month). Otherwise, you can buy a monthly plan for $29 every month for unlimited AI words.

4. AI Book Writer by Toolbaz

This tool offers a straightforward platform if you need quick drafts and creative ideas. You can produce coherent text based on prompts, making it a decent starting point if you want to flesh out story concepts or outline a book. To brainstorm book ideas, you can generate a 1000-word book outline with some details on the scene and characters. 

However, its simplicity is not very fascinating if you’re here for full-length book generation with AI. In addition to that, the generated content can lack depth and complexity, requiring significant revisions and additions to achieve a polished and engaging result. With this generic output, it becomes less ideal for writers looking for nuanced storytelling or intricate character development. 

If you are someone looking for a tool that can assist you with full-length books, then there are better tools with full-length book generation capabilities. You can think of it as a basic aid for story generation rather than a comprehensive tool for crafting a finished manuscript. 

Pricing: They do not offer any AI writing software for books to continue writing and storing your work. All of the writing happens on a live page with no history or record, making it a live tool for your writing practice.

5. AI Story Generator by Perchance

The AI Story Generator by Perchance is a creative tool for generating random story ideas and brief snippets. It’s great for quick inspiration or exploring unique story prompts, making it an enjoyable tool for brainstorming.  

However, its paragraph-by-paragraph output generation challenges with coherence, and continuity in a full-length manuscript. The tool feels more like a playful starting point than a serious writing assistant, as it requires significant input and effort from the user to turn its ideas into a book.

Pricing: Just like Toolbaz, Perchance does not offer any customized editor, which means it’s free. You can work directly on the live page and then copy once you’re done. 

6. AI Story Writer by Novel AI

This tool provides two distinct modes for book creation: Storyteller and Text Adventure. Storyteller allows users to write directly into a document while the AI generates supplementary content based on prompts. This gives you good control over your story’s direction. While, the Text Adventure creates dynamic situations where you can add actions or dialogue for the AI to build upon, more like a collaborative storytelling experience. 

This story generator requires manual refinement to align with your vision fully. This makes Novel AI more of a storytelling partner than an autonomous book generator. It is best for authors looking to combine creative manual input with AI-driven efficiency.

Pricing: They offer $10, $15, and $25/month price plans, and you can buy whichever suits your needs. 

7. AI Book Writer by ChatGPT for Story Creation

ChatGPT is a powerful AI tool for generating book-appropriate content. You can provide detailed prompts or broad concepts, and it effectively builds on these to develop coherent chapters, plotlines, and character arcs. 

It understands different genres and tones, which makes it suitable for fiction, non-fiction, and everything in between. 

However, for a 200-300 page book, you will find that character development or thematic consistency requires additional human effort to refine. 

As it is just a generic AI assistant, the output often includes common phrasing and overlooked details for highly creative or abstract concepts. 

In a pool of other high-performing book generators, ChatGPT’s is good solely for generating book summaries or expanding upon certain sections.  

Pricing: You’d need a ChatGPT account to access this tool. ChatGPT offers a free version with limited capabilities. Moreover, there are two paid versions, the first one costs $20 for extended limits, while the other is $200 for unlimited access to advanced models. 

8. AI Book Writer by CopyLime for Compelling Stories

This is a straightforward tool for generating book content, offering a clean and user-friendly interface that caters to writers at all skill levels. 

You can generate structured book drafts based on your prompts. You can provide details for each element, and it will come up with a customized storytelling version of the information you provide. 

While the tool looks simple, you must provide detailed prompts for each variable to produce meaningful results. It requires you to invest time in back-and-forth with prompts to refine the output to meet your vision.

Pricing: They offer a free version that allows writing up to 2000 words, while a yearly subscription of $348 provides you with an unlimited supply of words.
