One of the most challenging and rewarding aspects of creative writing is crafting compelling characters.

Characters are the heart and soul of any story, and they need to be believable, relatable, and memorable. 

But how do you create characters that stand out from the crowd and captivate your readers?

How do you breathe life into your fictional creations and make them feel real?

In this blog post, we’ll show you how to craft compelling characters with AI prompt ideas, using examples from various AI tools and genres. 

By the end of this post, you’ll have a better understanding of how to use AI prompt ideas to enhance your character creation process and improve your creative writing skills.

What are AI Prompt Ideas

AI prompt ideas are short phrases or sentences that you can use to generate images, text, or audio using AI tools such as Stable Diffusion, DALL-E, Midjourney, or ChatGPT

These tools use advanced neural networks to transform your prompts into creative outputs, often with surprising and impressive results.

AI prompt ideas can be a great source of inspiration and guidance for character creation, as they can help you:

Explore different aspects of your characters, such as their appearance, personality, background, motivation, and goals

Experiment with different genres, styles, and tones for your characters, such as fantasy, sci-fi, horror, comedy, or romance

Discover new possibilities and combinations for your characters, such as mixing and matching different traits, features, and elements

Overcome writer’s block and generate fresh and original ideas for your characters, especially when you’re stuck or bored

Strategies for Using AI to Craft Compelling Characters

Creating compelling fictional characters is key to writing an engaging story. Writers can use different AI tools to craft compelling characters. Strategies for using AI to craft strong, believable characters are given below

Get Background Ideas from AI

When conceptualizing a new character, it’s helpful to start with their backstory. Details about their upbringing, family life, education, interests, and pivotal life events will shape their personality and worldview. 

AI writing assistants allow you to instantly generate diverse backstories with just a few prompts.

You can give the AI basics like a character’s name, age, race, and gender. The AI will extrapolate unique details you may not have considered. This provides a jumping-off point to build upon with your ideas. 

The AI may unveil unexpected yet interesting backgrounds that inspire new character directions.

Use AI to Brainstorm Distinctive Attributes

The most memorable fictional characters have distinctive traits, perspectives, manners of speaking, quirky habits, etc.

AI tools can suggest random attributes to make your characters stand out in unexpected ways.

For example, you can prompt the AI to provide distinguishing attributes related to their appearance, personality, background, beliefs, likes/dislikes, habits, desires, fears, and ways of interacting with other characters. 

The AI might generate fascinating traits you’d never think of like a catchphrase, physical imperfection, hidden talent, phobia, addiction, unusual skill, etc.

Peruse the AI suggestions with an open mind, playfully choosing unique attributes to weave into your character that give them depth.

Lean on AI for Character Names and Meanings

The right character name can convey so much about someone’s background and personality.

An AI assistant can recommend suitable names that match your character’s cultural heritage and the history you’ve envisioned.

You can specify parameters like nationality, ethnicity, gender, era they live in, etc and the AI will provide fitting names.

You can also ask for name meanings and origins behind suggestions to guide your choice.

The AI may reference names of famous historical figures, renowned fictional characters, or lesser-known yet interesting names from literature. Work with the AI until you unearth the perfect name!

Use AI to Map Out Character Relationships

Well-crafted characters have complex, engaging relationships that evolve.

An AI tool can diagram how your characters relate to one another including their emotional bonds, tensions, alliances, rivalries, power dynamics, secrets kept, misconceptions, influence on each other, etc.

Start by listing all your main characters. Then specify relationships between different characters for the AI to map out, filling in connecting dots you may have overlooked.

The relationship diagram may reveal new plot-driving conflicts and intriguing character pairings you can develop.

Employ AI to Gauge Character Plausibility

As you flesh out details about each imaginary person in your story, you’ll want to ensure they feel multi-dimensional yet believable. AI writing assistants allow you to assess just how plausible a character feels.

Copy and paste your profile of each character including their backstory, personality traits, motivations, worldview, etc.

Ask the AI: “Does this character feel believable and realistically nuanced based on their background and traits?” The AI will analyze and let you know if the character needs adjustment along with targeted feedback.

This allows you to fine-tune characters that may initially come across as too extreme, simplistic, inconsistent, or unrealistic.

The AI guides you in crafting well-rounded characters an average reader can relate to.

Utilize AI to Compare Characters

It’s helpful when conceptualizing your cast of characters to use contrast techniques – making some characters foils of one another.

This allows you to highlight differences in personality, values, abilities, beliefs, and leadership styles that can heighten tension and conflicts.

Copy and paste profiles of two characters into an AI writing assistant. Ask the AI: “Contrast these characters highlighting stark differences in background, personality, abilities, beliefs, and goals.” 

The AI will compare and contrast the characters, revealing conflict-driving ways they diverge so you can amplify your storytelling.

Tap AI to Generate Character Motivations

Well-constructed fictional people have clear motivations driving their behavior. The AI can serve up impactful motivations explaining why characters act the way they do.

For each character, specify basics like their name, age, background, goals, etc. Then query: “Provide 5 unique motivations that explain why this character pursues their goals and makes certain choices.”

Peruse the AI’s list of motivations assessing if they align with the character backstory you envisioned.

Select the motivations that resonate and weave them organically into the character’s development arc.

Utilize AI to Strengthen Character Agency

Well-crafted characters need a strong sense of agency where their choices and actions fuel outcomes.

An AI writing assistant can analyze characters and provide feedback on how to strengthen their agency.

Copy and paste character profiles into the AI tool. Ask: “How can I enhance this character’s agency and empower them to drive more of the story outcomes?” The AI will assess if characters lack sufficient agency and seem passive. 

It will advise how to pivot so the character makes bolder choices moving the story ahead.

Employ AI to Generate Key Character Scenes

It’s essential fictional characters have compelling signature scenes showcasing their personality, values, abilities, and growth arcs.

Rather than racking your brain, have an AI writing tool instantly craft impactful scenes for each main character.

For every protagonist and antagonist specify their name, role in the story, background, motivations, abilities, and personality. Query: “Provide a pivotal, intense scene showcasing this character’s motivations and abilities in action.”

Review the unique scenes the AI generates. Look for standout moments you may integrate to showcase why this character matters in moving your overall story forward.

The AI might reveal new directions or outcomes you can incorporate surrounding each character.

Use AI to Assess if Characters Align with Genre

You may be conceptualizing characters without fully realizing if they organically align with the overarching genre of your book or screenplay.

An AI assistant can assess characters and advise if they fit conventions expected in genres like mystery, romance, sci-fi, fantasy, etc.

Copy and paste your character descriptions. Ask the AI: “Do these characters logically align with a [mystery] genre based on their backstories, attributes, roles, and character arcs?” 

The AI will analyze if the characters break or align with expected tropes to satisfy genre-specific reader expectations.

This allows you to tweak characters so they feel cohesive with fan conventions expected in the fictional genre you are writing for. You can retain creative freedom while still meeting audience expectations.

Summarize Key Character Details with AI

As you develop your cast of characters referenced throughout a lengthy story or script, it becomes crucial to track relevant details.

Rather than maintaining endless notes and profiles on each character, utilize an AI tool to instantly summarize need-to-know details on demand.

When wanting to recall specifics on a particular character, simply query the AI:

“Summarize key details about [character name] including their background, role in the story, personality traits, abilities, beliefs, motivations, character arc, and relationship with other characters in 2-3 sentences.”

The AI will concisely distill the most crucial details so you recall only impactful elements for crafting scenes, conflicts, and growth arcs for each imaginary person.

How to Craft Compelling Characters with AI Prompt Ideas

The Writers need to follow some steps so they can create an output according to their imagination. Following are the steps to craft a compelling character with AI prompts

Step-1: AI Tool Selection

The first step to crafting compelling characters with AI prompt ideas is to choose an AI tool that suits your needs and preferences.

There are many AI tools available online, each with its strengths and limitations. Some of the most popular and powerful ones are given below:

Stable Diffusion

A tool that generates realistic and high-quality images from text prompts, using a technique called stable diffusion.

It can produce stunning visual art in various styles and genres, such as anime, portraits, landscapes, and abstract. 

You can use Stable Diffusion to create images of your characters, their settings, or their actions. You can also use it to experiment with different art styles and effects for your characters, such as lighting, texture, and color.


A tool that generates images from text prompts, using a technique called variational autoencoder. It can produce diverse and creative images that often combine or transform different objects, concepts, or attributes. 

You can use DALL-E to create images of your characters, especially if you want to explore unusual or imaginative combinations, such as a cat with a human face, a dragon with butterfly wings, or a pineapple wearing a hat.


A tool that generates text from text prompts, using a technique called transformer. It can produce coherent and fluent text in various formats and genres, such as stories, essays, poems, and lyrics. 

You can use Midjourney to create text for your characters, such as their dialogue, narration, description, or thoughts.

You can also use it to experiment with different genres and tones for your characters, such as horror, comedy, or romance.


A tool that generates text from text prompts, using a technique called generative pre-trained transformer. It can produce conversational and interactive text, such as chat messages, tweets, or comments. 

You can use ChatGPT to create text for your characters, especially if you want to simulate their communication or interaction with other characters or readers.

You can also use it to experiment with different personalities and moods for your characters, such as friendly, sarcastic, or angry.

Step 2: Choose the Prompt

The second step to crafting compelling characters with AI prompt ideas is to choose a prompt that describes or defines your character. A prompt is a short phrase or sentence that you input into the AI tool to generate an output. 

A prompt can be as simple or as complex as you want, depending on your goal and creativity. A prompt can also be specific or vague, depending on your level of control and flexibility.

Some examples of prompts for character creation are:

A young girl with curly hair and glasses who loves to read and write

A cyberpunk hacker with a robotic arm and a neon mohawk

A vampire detective who solves crimes in a dark and rainy city

A cheerful and optimistic alien who wants to make friends with humans

A grumpy and lonely wizard who lives in a tower with his cat

Step 3: Generate an Output

The third step to crafting compelling characters with AI prompt ideas is to generate an output from the AI tool using your prompt. An output is the image, text, or audio that the AI tool produces based on your prompt. 

An output can be realistic or abstract, depending on the AI tool and the prompt. Output can also be consistent or varied, depending on the AI tool and the prompt.

Some examples of outputs for character creation are:

A young girl with curly hair and glasses who loves to read and write

A cyberpunk hacker with a robotic arm and a neon mohawk

A vampire detective who solves crimes in a dark and rainy city

“He walked through the rain-soaked streets, his trench coat and fedora hiding his pale skin and sharp fangs. He was a vampire, but he didn’t prey on humans. He hunted down the criminals and monsters that lurked in the shadows of the city. He was a detective, but he didn’t work for the police. He worked for himself, following his code of justice. He was a loner, but he didn’t mind. He had a job to do, and he did it well. He was a vampire detective, and he was on the case.”

A cheerful and optimistic alien who wants to make friends with humans

“Hi, I’m Zeebo, and I’m from planet Zorb. I came to Earth to learn more about your culture and make some friends. I think humans are very fascinating and fun. I like your music, your movies, and your food. I especially like pizza and ice cream. Yum! I also like to play games, tell jokes, and give hugs. I’m very friendly and outgoing, and I always try to see the bright side of things. I hope you’ll like me too, and we can be friends. What do you say?”

A grumpy and lonely wizard who lives in a tower with his cat

“He sat in his tower, surrounded by books and scrolls. He was a wizard, but he didn’t care for magic. He found it tedious. He preferred to read and study, learning about the mysteries of the universe. He was a scholar, but he didn’t share his knowledge. He kept it to himself, fearing that others would misuse it or mock it. He was a recluse, but he didn’t want to be. He longed for companionship and conversation, but he didn’t know how to find it. He had only one friend, his cat, who curled up on his lap and purred. He was a grumpy and lonely wizard, and he wished for more.”

Step 4: Evaluate and Refine

The fourth step to crafting compelling characters with AI prompt ideas is to evaluate and refine your output.

Evaluation is the process of assessing the quality and relevance of your output, based on your goals and expectations.

Refinement is the process of improving and modifying your output, based on your feedback and creativity.

Some of the criteria for evaluating your output are:

Accuracy: How well does the output match your prompt? Does it capture the essence and details of your character? Does it avoid errors or inconsistencies?

Diversity: How different is the output from your prompt? Does it add new or unexpected elements to your character? Does it avoid repetition or clichés?

Coherence: How well does the output fit together? Does it form a logical and consistent whole? Does it avoid gaps or contradictions?

Fluency: How well does the output flow? Does it use clear and natural language? Does it avoid grammar or spelling mistakes?

Creativity: How original and interesting is the output? Does it spark your imagination and curiosity? Does it avoid dullness or blandness?

Some of the methods for refining your output are:

Editing: How can you change or correct the output? Can you fix any errors or inconsistencies? Can you improve the clarity or naturalness of the language?

Expanding: How can you add more to the output? Can you include more details or features of your character? Can you extend the length or depth of the output?

Reducing: How can you remove less from the output? Can you eliminate any unnecessary or redundant elements from your character? Can you shorten or simplify the output?

Combining: How can you merge different outputs? Can you use multiple AI tools or prompts to create a composite output? Can you blend different styles or genres for your character?

Revising: How can you change the output completely? Can you use a different AI tool or prompt to generate a new output? Can you alter the theme or tone of your character?

Step 5: Use Your Output as a Starting Point for Your Creative Writing

The fifth and final step to crafting compelling characters with AI prompt ideas is to use your output as a starting point for your creative writing.

Output is not the end goal, but the beginning of your creative writing. Output is not a final product, but a raw material for your creative writing. Output is not a substitute, but a supplement for your creative writing.

You can use your output as a source of inspiration, guidance, and feedback for your creative writing. You can use your output to:

Develop your characters further, such as their backstory, relationships, conflicts, and arcs

Incorporate your characters into your plot, setting, theme, and style

Experiment with different scenarios, events, and outcomes for your characters

Compare and contrast your characters with other characters or real people

Share your characters with other writers or readers, and get their opinions and suggestions

Ultimate Goal

The ultimate goal of crafting compelling characters with AI prompt ideas is to create stories that are engaging, meaningful, and enjoyable for you and your audience.

AI prompt ideas can help you achieve that goal, but they can’t do it for you. You still need to use your imagination, creativity, and skill to turn your output into a story. You still need to use your voice, vision, and passion to tell your story.

AI prompt ideas are not a magic bullet, but a powerful tool. They are not replacements, but a partner. They are not a constraint, but a challenge. They are not a limit, but a possibility.


Constructing multi-dimensional fictional people filled with agency is no easy feat. Fortunately, AI writing assistants can make lightning-quick suggestions to overcome writer’s block at every step from conceptualizing to tracking characters.

Learn to strategically collaborate with AI tools to unlock creativity you didn’t know you had. Soon you’ll dream up vivid, evocative characters far beyond anything you could conceive alone.

Here are helpful prompts to guide you in leveraging AI as a characterization muse:

“Provide a unique three-sentence backstory for a 25-year-old, female, teacher protagonist named Gabriela Santos.”

“Suggest two contrasting personality traits describing tech CEO antagonist Miguel Torres related to his workaholism.”

“What are personality differences between a soldier character Valerie Smith and rebel leader character Aidan Zhou to heighten conflict?”

“Does supernatural detective character Raj Singh feel believably nuanced based on his 1930s upbringing and psychic abilities?”

Keep exploring prompts framing fictional people from new angles. Before you know it, you’ll have pages filled with players in your heart-racing next thriller crying out for their stories to be told!
