When I first sat down to write a book with AI, I wasn’t sure what would come out. There was this fear. What if the AI just didn’t get me? Which made me hold back a little, but when I gave these AI tools to write a book my prompt and saw my thoughts turn into a compiled scene, it genuinely moved me. I remember sitting there, smiling, even a bit emotional, watching my scattered ideas come to life.
Whether you’re a new writer, a parent trying to teach a lesson through story, or just someone exploring creative expression for social media, then this guide on how to write a book using AI is for you. I’ve explored the best AI tools to help you go from idea to finished page, no matter where you’re starting.
Best AI Tools to Write a Book

I started using Toolsmart’s Story Generator when I was looking for a quick way to bring an idea to life,and it didn’t disappoint.. It quickly understood my assignment and was smooth and straightforward to use. As soon as I entered my prompt, it already had the storyline ready. Just type a prompt, and within seconds, you get a full story with a clear structure. I’ve used it to experiment with bedtime tales, moral stories, and even social media posts. It’s not just fast, it’s genuinely surprising how coherent the stories are, even without needing an account.

No login or account required
Instant story generation by genre
Built-in rewriting and paraphrasing tools

No long-term document storage
Less suitable for technical or non-fiction writing

Step 2: Now write your story prompt in the source text area on the left side of the screen.

2. Claude Pro
Claude Pro is my go-to for serious writing sessions. When I’ve got an outline or a few scenes in mind, Claude picks them up and expands them with incredible consistency. It’s especially helpful when I’m working on deeper narratives with multiple characters or tones. What sets it apart is how well it remembers and builds on earlier parts of the story. The interface is smooth and easy to use, making the writing flow naturally. However, it’s not unlimited..
Pros
Maintains long-form context
Great for editing, outlining, and drafting
Generates realistic dialogue and structured chapters
Cons
Paid subscription required for full features
Slightly slower than smaller tools
A step-by-step guide
Claude by Anthropic does a great job at generating stories, and what I liked most is how it presents the story in a separate section, making it easier to read and follow. Here’s how I used Claude to create a special little story:
Step 1: Open Claude in your browser, or you can also download their desktop application.
Step 2: Once it's open, make sure to sign up or log in using your email, as Claude currently doesn't offer any other login options (unlike other AI tools).
Step 3: Now simply paste your story idea as a prompt in Claude. Type in as much detail as you can to help Claude generate a story that matches your style and imagination, then press "Enter".
Step 4: Your story will be generated in a separate section on the right, making it easier to read.
3. Gemini Advanced (Google)
Gemini Advanced is where I go when I want to play. It’s amazing for shifting styles—like turning horror into comedy or sad endings into hopeful ones. I’ve created wild twists just to see where the story could go. It integrates well with Google Docs, so I can work without switching apps. It’s great for creative rewrites with minimal effort. It’s fast and responsive, but sometimes needs clearer direction for longer arcs. Still, it’s perfect for experimenting and quick scene shifts.
Pros
Quick genre/style rewrites
Google Docs integration
Great for scene experimentation
Cons
Struggles with maintaining long context
Can drift from your story’s voice
A step-by-step guide
Gemini can be fun to use, but when it comes to creating stories, you might need a bit of practice. That’s because the prompts need to be detailed for the best results. If you’re just starting out, here’s how you can generate a simple story using Gemini:
Step 1: To use Gemini, open it in your browser or mobile app.
Step 2: Once you're in, type your prompt into the chatbox. Make sure it’s detailed so Gemini knows exactly what kind of story you want. Then press "Enter".
Step 3: Gemini will generate a story based on your input. You can keep experimenting by changing parts of your prompt or adding more details to build on the story.
4. ChatGPT (OpenAI)
Writing with ChatGPT feels like talking to a co-author.I’ve discussed character arcs, rewritten dialogue, and even planned trilogies. It adapts to your voice, and with memory, remembers your style too. The back-and-forth makes brainstorming easy and natural. It’s also incredibly accessible,just open and start typing. Just be aware it can get repetitive without clear direction. Still, it’s great for feedback, new ideas, or when you’re stuck mid-draft.
Pros
Highly interactive and responsive
Supports memory and custom GPTs
Great for brainstorming, fixing pacing, and story arcs
Cons
Premium version required for advanced features
May lose thread in extremely long projects
A step-by-step guide
Chances are, like most people, you’ve probably used ChatGPT as an everyday AI assistant. But let me show you how you can take it a step further; by using prompts to turn ChatGPT into your personal AI story generator.
Step 1: Open ChatGPT on your browser or app, just like you normally would.
Step 2: Think of a story idea. It can be anything; a superhero in school, or a reimagining of one of your favorite Disney movies. Type your idea as a prompt, add some details, and hit "Enter".
Step 3: You’ll see ChatGPT writing your story, line by line, right on your screen. Once it’s done, take your time to read it. If you want to save it, you can copy and paste it into an app like WPS Writer to keep it safe.
5. Notion AI
If you like having everything in one place notes, outlines, timelines then Notion AI is for you. I use it for character sheets, chapter tracking, and plot twist planning. It’s more of an organizer than a writer, but excels at structure. Templates and flexibility save tons of time. It’s best for long-term projects or when planning gets complex. Story generation is limited though,pair it with another AI for writing.
Pros
Combines writing, planning, and AI
Best for notes, outlines, and tracking progress
Simple, distraction-free interface
Cons
Not strong in creative story writing
More of a companion than a core writing tool
A step-by-step guide
While Notion is a great tool for staying organized, I’ve also been using its AI to generate stories—and the best part is, they’re saved automatically, so you can easily come back to them anytime. Here’s how you can create a story using Notion AI:
Step 1: First, open Notion in your browser and log in to your Notion account.
Step 2: Once you're in, click on the "New" icon to create a fresh page. Then press the spacebar to activate the Notion AI assistant.
Step 3: Type in your story prompt; the idea you want the AI to write about, and press "Enter" to start generating.
Step 4: Your story will appear right on the same page. You can either accept it if you’re happy with it, or reject it and try again with a new prompt.
