How to Brainstorm Story Ideas Using AI: 7+ Creative Writing Tips

How to Brainstorm Story Ideas Using AI

Feeling skeptical about using AI for help with creative writing? You’re not alone. As a professional screenwriter and novelist I’ve had the same doubts over the past few years as AI use has been widely adopted in many industries.

Talking about AI in creative fields brings up all sorts of issues and debates, and I’ll be the first to say that AI should be simply a tool for human writers to use, not something that you should expect to write ‘for’ you.

Now, one thing that AI is actually very good at is brainstorming story ideas! So, in this article you’ll learn:

  • How to use AI to brainstorm story, character, setting, and plot ideas.

  • Which tools are worth trying out for creative writers.

  • How to balance AI ideas with your own creativity.

Let’s get into it!

How AI Can Assist in Brainstorming

AI can be a great tool for brainstorming. By giving your AI tool a few keywords or prompts, it can give you lots of creative suggestions for all sorts of different aspects of storytelling.

I’ve tried using AI for idea generation, and it’s actually helped me find unique ideas that I wouldn’t have thought of on my own.

I’ve found that AI can really help kickstart my brainstorming process and help me overcome writer’s block.

Examples of AI-Generated Story Concepts

Here are some ways AI can generate story ideas:

  • Plot Ideas: Input a basic scenario, and AI can expand it into a full plot. It can also take your general plot points and turn it into a full beat sheet for a screenplay or novel (I make no guarantees on how good this beat sheet will be though!).

  • Character Profiles: Describe some basics of your character, and AI can flesh out their background and traits.

  • Setting Descriptions & Worldbuilding: Provide a setting, and AI can detail the environment and mood. It can give you ideas for each part of the worldbuilding process!

How to Brainstorm Story Ideas Using AI

In general, there are some key components of a story that I find AI to be helpful with brainstorming ideas for. These include my characters, my settings, my worldbuilding, and my plot points and plot twists.

Let’s take each of these and I’ll show you how you can use AI to help you generate ideas!

Use AI to Brainstorm Story Characters

My favorite way to brainstorm story character details is by using a creative writing AI tool like Sudowrite or Novelcrafter. My favorite of these for brainstorming is Novelcrafter, as it lets you input all of your existing story details into the “codex” – and then it will use that information when you use the “chat” function.

Chat-GPT is helpful in the very beginning stages of brainstorming, but not in later stages where you already have some of the details set. It doesn’t have a way to add in all the existing story information as context for the AI, so it won’t be able to ‘remember’ and use your existing info in the same way that a creative-writing focused AI program can do.

Here are some starter prompts you can adapt to get ideas for characters:

Name ideas: Give me 20 ideas of names for a mom character from a story set in the 1920s.

Appearance and Physical Traits: I’m writing a character who is 35, female, ordinary-looking, and works with cars. Give me some ideas for her appearance.

Occupation Ideas: Give me 20 ideas for jobs that an 18 year old boy might have had back in 1850.

Character Traits: I’m writing an apocalyptic story with an alien whose planet has been destroyed as the main character. He’s going to seem helpful to humans at first, but then he’ll betray them. Give me 10 potential character traits that he might have.

Personality Type: Give me three different personality descriptions for the dad character in a coming-of-age story. Use enneagram types please.

Backstory Ideas: I’m writing a character who is tormented by events that happened between her and her best friend when they were on holiday together in Bali, 10 years ago. Give me ten different backstory ideas for this situation and character.

Dialogue or Catchphrase Ideas: Give me 10 potential catchphrases my 10 year old, baseball-loving protagonist might have in a comedic story.

Other Kinds of Brainstorming for Story Development

One interesting use of AI is to take your existing character backgrounds, conflicts, and settings, and ask the AI to reimagine them in various cultural and social standpoints.

For instance, I might input basic story elements and then ask the AI to reinterpret them through a different genre or time period. This technique of creative thinking gives me tons of new angles to explore in my story:

  • Genre Twist: Place a traditional fairy tale in a cyberpunk setting.

  • Time Swap: Imagine a Roman gladiator in the modern corporate world.

  • Cultural Reinterpretation Reimagining a love story in a medieval Japanese setting.

  • Social Contexts Transform a family drama into a futuristic society with advanced technology.

  • Reverse Roles Switch the roles of hero and villain in a classic adventure story.

  • Environmental Change Set a crime thriller in an isolated, underwater research facility.

  • Political Shift Transpose a medieval kingdom’s political intrigue into a contemporary high school setting.

  • Technological Leap Turn a historical drama into a story set in a virtual reality world.

  • Economic Flip Place a post-apocalyptic survival tale in a utopian society where resources are abundant.

  • Cultural Mashup Blending elements of ancient Greek mythology with modern urban life.

The Best AI Story Generator Tools

AI story generators, like Novelcrafter and Sudowrite, are specialized programs that are designed to produce creative, story-driven content. Here’s my quick take on the best ones:

  • Novelcrafter: The best AI creative writing program overall. It’s great if you know what you’re doing with fiction writing. Novelcrafter is the most flexible of the AI storytelling programs, and it’s got the best ways to organize and keep all of your story’s details so that the AI can ‘remember’ and use those details when you’re brainstorming with it.

  • Sudowrite: The best AI storytelling tool for beginners or anyone who has challenges with traditional fiction writing. This AI tool supports you every step of the way, from designing your characters and their world to developing the plot points and innovative ideas for your story. It just might be a bit frustrating if you’re an experienced creative writer.

Sudowrite does have a dedicated ‘brainstorming’ tool that can be helpful to beginners. However, I think that most brainstorming for stories and creative writing is best done using Novelcrafter’s ‘chat’ function.

Ensure Creativity and Originality

While artificial intelligence is a helpful tool, but don’t let it do all the work. It works best when you use it to generate ideas, rather than having it write giant section of your story. Always make sure your unique voice as a writer shines through in your work. AI should enhance your innate human creativity, not replace it.

Always try to find a balance between AI-generated ideas and your own creativity. Use AI to brainstorm, then build on those ideas with your own imagination. This way, you stay in control of your story, and you can be sure that your story remains just that – yours!

Potential Limitations and Ethical Considerations

Know that AI has many limits. It can’t understand nuanced themes or emotions like humans can. Often, AI-generated content is repetitive and lacks the depth that only a human can provide. It’s important to use AI as a tool, not a crutch.

Also, know that AI can reflect biases present in its training data. Make sure your prompts are inclusive and fair.


AI tools are incredibly useful for brainstorming story ideas, but remember, they are just tools. Please don’t rely on them to write your whole story!

If you’re going to write a novel, short story or movie screenplay, you’ll need to know more about story structure, character development, and plot pacing.

Always keep learning, exploring and improving your writing skills. Happy writing!
