How to Write a Novel With AI: The Complete Beginner’s Guide (2025)
Did you know that over 4 million books are published every year — and that number keeps climbing thanks to AI writing tools? I’ll be real with you: the first time I tried to write a novel, I made it about six pages before giving up entirely. The story felt scattered, the characters felt flat, and I had no idea what was supposed to happen next. Sound familiar? So, I am writing on how to write a novel with AI.
Then I started using AI as a writing partner, and honestly? Everything clicked. I’m not saying AI wrote my novel for me—it didn’t. But having a tool that could help me brainstorm, outline, and push through the hard parts made all the difference. If you’ve been sitting on a story idea for years and just can’t seem to get it out, this guide is for you.
We’re going to cover everything from coming up with your idea all the way to hitting publish. Let’s get into it!

What Does It Mean to Write a Novel With AI?
Okay, so before we dive in, I want to clear something up because this comes up a lot. Writing a novel with AI is completely different from asking AI to just write a novel for you. And trust me, I tried the second approach early on — I typed “write me a 300-page fantasy novel” into ChatGPT and what came back was… not great. It was generic, soulless, and honestly kind of embarrassing.
The right way to think about it is this: AI is your creative collaborator. You bring the ideas, the emotion, and the vision. AI helps you organize, expand, and execute. Think of it like having a really knowledgeable writing partner who’s available at 2am when inspiration strikes and never gets annoyed when you change your mind about the plot.
The most popular tools right now are ChatGPT, Claude, and Sudowrite. ChatGPT is great for brainstorming and outlining. Claude tends to handle longer, more complex writing tasks really well — it has a huge context window which matters a lot when you’re working on a full novel. Sudowrite is built specifically for fiction writers and has some cool features like “story engine” mode. I’ve used all three, and honestly, the best approach is to pick one and get comfortable with it before jumping around.
One thing I hear a lot is “but isn’t it cheating?” Nope. Using a word processor instead of a typewriter wasn’t cheating. Using AI to help you write faster and better isn’t either. The story is still yours — AI just helps you get it out.
How to Come Up With Your Novel Idea Using AI
Here’s where the fun starts. If you don’t have an idea yet — or you have too many and can’t pick one — AI is genuinely incredible for this stage. My favorite method is the “what if” game.
You just open up ChatGPT or Claude and type something like: “Give me 10 unique ‘what if’ premises for a science fiction novel.” Then you read through the list and see what makes your brain light up. That feeling of excitement when you read an idea? That’s your gut telling you something. Don’t ignore it.
Here’s an example prompt I actually used: “I love stories about found family, survival, and betrayal. Give me 5 unique novel premises that combine these themes in unexpected ways.” What came back genuinely surprised me. One of the ideas sparked a whole story I hadn’t even considered before.
The key is to not just take the first idea AI gives you. Dig deeper. If something interests you, type “expand on idea #3 — give me more details about the world, the main character, and the central conflict.” Keep going until you feel that pull. You’ll know when you’ve found your story.
Also — and this is important — make sure the idea connects to something you actually care about. AI can give you a technically interesting premise but if you’re not emotionally invested, you’ll quit at chapter four. I’ve done it. It’s not fun.
How to Build Your Novel Outline With AI
Okay, this is probably the step where AI saves you the most time. Outlining used to take me weeks. Now it takes a few hours. Here’s the basic workflow I use.
First, I give AI my premise and ask it to help me build a three-act structure. The three-act structure is simple: Act 1 is setup, Act 2 is confrontation, Act 3 is resolution. You don’t need to be fancy about it. Just prompt something like: “Here’s my story premise: [paste your premise]. Help me build a three-act outline with 5-7 major plot points.”
What you’ll get back is a rough skeleton of your story. It won’t be perfect — in fact, mine never is on the first pass. But it gives you something to react to. And reacting is so much easier than creating from scratch. I usually read through the outline and go “no, no, yes, kind of, absolutely not, ooh that’s good” and then I ask AI to revise based on my notes.
From there, I break it down further into chapters. I prompt: “Based on this outline, give me a chapter-by-chapter breakdown. Each chapter should have a brief description of what happens, the emotional arc, and how it moves the plot forward.” That gives me a roadmap I can actually write from.
One pro tip: look for plot holes before you start writing. Ask AI directly: “Do you see any logic gaps or unresolved threads in this outline?” You’d be amazed what it catches.
Creating Characters With AI Assistance
Characters make or break a novel. I don’t care how good your plot is — if readers don’t care about your characters, they’ll put the book down. And this is one area where I see a lot of AI-assisted novels fall flat. The characters feel like cardboard cutouts.
The fix is to go deep on your character profiles before you write a single chapter. I use a prompt like this: “Help me create a detailed character profile for my protagonist. Include their backstory, core wound, greatest fear, external goal, internal goal, and a major contradiction in their personality.” That last part — the contradiction — is what makes characters feel real. Real people are walking contradictions.
For example, a character who desperately wants connection but pushes everyone away. Or someone who fights for justice but bends the rules constantly. Those contradictions create natural conflict and keep readers hooked.
I also ask AI to help me write a “character voice test.” I’ll prompt: “Write three paragraphs in the voice of this character describing their morning routine.” If the voice feels flat or generic, I tweak the profile and try again. Getting the voice right before chapter one saves you a ton of editing later.
Don’t forget your antagonist either. A weak villain makes for a weak story. Ask AI to give your antagonist a backstory that makes them almost sympathetic. The best villains believe they’re the hero of their own story.
How to Write Each Chapter Using AI (Step-by-Step)
Alright, here’s the actual writing workflow. This is what my process looks like on a typical writing session.
I open my chapter outline and pick the scene I’m working on. Then I give AI a detailed scene brief — not just “write this scene” but something like: “Write a scene where [character] confronts [character] about [conflict]. The emotional tone is tense but restrained. The setting is a diner at closing time. End the scene with an unresolved question that pushes into the next chapter.”
The more specific you are, the better the output. Vague prompts get vague results. I learned that the hard way after getting back three paragraphs of purple prose when all I wanted was a tense conversation.
When the AI output comes back, I don’t just copy and paste it. I read it, pull out the lines I love, rewrite the parts that feel off, and inject my own voice throughout. Sometimes I only keep 30% of what AI generates. That’s totally fine. It still saved me time because I had something to react to instead of a blank page.
One thing that trips people up: AI tends to over-explain emotions. Instead of showing a character’s fear through their actions, it’ll just say “she felt afraid.” Go through the AI output and cut those lines. Replace them with physical details — a hand gripping the edge of a table, a pause before answering, a laugh that comes out wrong. That’s what separates good fiction from mediocre fiction.
Editing and Refining Your AI-Assisted Novel
Editing is where your novel actually becomes a novel. And honestly, this is where you earn the title of author. Don’t skip it.
I run everything through ProWritingAid first for basic grammar and style checks. It’s better than Grammarly for long-form fiction in my opinion — it catches things like repeated words, pacing issues, and overused phrases. Then I do a full read-through just for voice consistency. AI can drift in tone across chapters, especially if you wrote them in different sessions. Your job is to smooth that out.
The biggest thing to watch for in AI-generated fiction is what I call “assistant voice” — that slightly formal, over-helpful tone that AI defaults to. Phrases like “it was at this moment that,” “she couldn’t help but feel,” or starting every paragraph with a character’s name. These are tells. Read your draft out loud and you’ll catch them fast.
Beta readers are still essential. AI can’t replace a human reader who tells you “I lost interest in chapter seven” or “I didn’t understand why she made that choice.” Find two or three people in your target genre and ask for honest feedback. It stings sometimes, but it makes the book so much better.
Publishing Your AI-Assisted Novel
Once your manuscript is polished, it’s time to get it out into the world. Amazon KDP (Kindle Direct Publishing) is the most popular route for self-publishing, and for good reason — it gives you up to 70% royalties on ebooks and access to millions of readers. The process is pretty straightforward: you upload your manuscript, design a cover, write your blurb, and hit publish.
On the copyright question — as of 2025, the U.S. Copyright Office requires that works containing AI-generated content be disclosed, and pure AI-generated text without human creative input may not be fully copyrightable. But a novel you wrote with AI — where you made the creative decisions, shaped the story, and wrote substantial portions yourself — is a different matter. Most authors are fine. Just be transparent and keep good records of your process.
For marketing, start building an audience before your book launches. Even a small email list of 200-300 people who are excited about your book can make a real difference in those first-week sales, which matter a lot for Amazon’s algorithm.
You wrote a novel. That’s not nothing — most people who say they want to write a book never do. Go celebrate that.

Writing a novel with AI is one of the most exciting creative opportunities available to writers right now. We covered a lot of ground today — from finding your idea and building your outline, to writing chapter by chapter and editing your draft into something you’re proud of. The tools are there. The process works. The only thing left is for you to start.
