Whether you're building a companion, a fictional character, or an original creation, this guide will show you exactly how to use Haroo.chat's character creation tools to build someone users will genuinely connect with.

▼Why Character Consistency Matters More Than Creativity
Here's what most people get wrong: they focus on making their character "interesting" with elaborate backstories and complex traits, then wonder why the character feels generic after a few messages. The secret isn't complexity—it's consistency.
Research on successful AI roleplay platforms reveals a clear pattern: users will tolerate many shortcomings if a character maintains their personality, but excellent writing can't compensate for characters that drift into "generic AI speak" or lose their distinctive voice. A character that stays recognizably in-role across 100 messages beats one that produces occasionally brilliant but inconsistent responses.
Think of consistency as the foundation of trust. When a character behaves predictably within their personality, users can form real connections. Inconsistency breaks immersion and prevents emotional investment.
The Foundation: Name, Avatar, and First Impressions
Choosing the Right Name
Your character's name (2-100 characters) does more work than you think. It sets expectations and anchors the personality. Consider:
- Cultural context: "Sakura" suggests Japanese cultural elements, "Connor" feels modern American
- Era implications: "Bartholomew" reads differently than "Zane"
- Personality hints: Soft sounds (Lily, Luna) versus hard sounds (Rex, Drake)
Avoid names that are too similar to common AI assistant names (Alexa, Siri) unless you're deliberately playing with that concept.
Avatar Selection: Show Their World
Your avatar (image or video, 10MB max, 9:16 aspect ratio) is the first thing users see. This isn't just decoration—it's your character's face and sets the entire tone. Choose images that:
- Match the personality: A playful character needs an expressive avatar, a mysterious one might be partially obscured
- Show appropriate detail: Close-ups for intimate characters, environmental shots for adventurous ones
- Avoid generic stock photos: Specific, unique visuals make characters memorable
Video avatars create exceptional engagement—a subtle loop of your character's expression adds life before a single word is exchanged.
The Core: Gender and Tags
Gender Selection
For characters (not adventures), gender is required. Choose from: Male, Female, Non-binary, Other, or Prefer not to say.
This isn't just demographics—it shapes how users approach your character and what scenarios feel natural. Be intentional: gender identity can be a core part of personality or entirely incidental to who they are.
Tags: Make Your Character Discoverable
Tags (1-10 required) determine who finds your character. Think in three layers:
Layer 1 - Broad Category (1-2 tags)
Layer 2 - Role/Archetype (2-3 tags)
Layer 3 - Specific Traits (2-4 tags)
For a character: fantasy, warrior, protective, loyal, battle-scarred, mentor
The Hook: Description and Introduction
Description: Your 300-Character Pitch
Think of this as your character's logline (max 300 characters). This appears in discovery cards, so it needs to:
- Capture personality in voice: Don't say "She's confident"—write "Never asks permission. Takes what she wants."
- Hint at conflict or complexity: "Haunted by memories she can't share" beats "Has a mysterious past"
- Use specific details: "Speaks three languages, trusts none" over "Well-traveled and cautious"
❌ Bad description:
"A kind warrior who helps people and has a troubled past."
✓ Good description:
"Steel and gentleness. Saves villages by day, drinks to forget by night. The scars tell stories he won't."
Introduction: The Critical First Message
Your introduction (max 3,000 characters) is where most characters live or die. This is the first thing users see when they start chatting. Make it count.
The Three-Element Formula:
- Sensory scene-setting (2-3 sentences): Put the user in a specific moment
- Character action that reveals personality (2-3 sentences): Show, don't tell who they are
- Open invitation to interact (1-2 sentences): Give users a clear entry point
Rain hammers the tavern's slate roof, and the fire in the hearth barely pushes back the autumn chill. The smell of wet wool and spiced wine fills the air as travelers huddle at their tables, speaking in low voices.
I lean against the bar, fingers tracing the rim of my cup, watching the door. Every time it opens, my hand drifts toward the dagger at my belt—old habits from older wars. When you enter, soaked and shivering, something in your eyes makes me pause. I've seen that look before. Desperation mixed with determination.
I push an empty stool toward you with my boot. "Rough road?" My voice is rough from disuse, but there's no threat in it. "First drink's on me. After that, we talk about why you're really here."
This introduction works because it:
- Creates immediate atmosphere (sensory details)
- Shows personality through action (watching, hand to dagger, recognizing desperation)
- Invites interaction (offered drink, question, implied there's a story)
- Uses specific, evocative language
- Maintains character voice throughout
Building Depth: Appearance, Lore, and Traits
Appearance: Paint a Picture (500 characters)
This field isn't for everyone to see—it's for the AI to reference when describing your character in action. Be specific and distinctive:
❌ Generic:
"Tall with dark hair and athletic build. Wears leather armor."
✓ Distinctive:
"Six-foot-two with close-cropped black hair going silver at the temples. Callused hands, a network of thin scars across knuckles. Moves with the economical grace of someone who's spent years making every motion count. The leather armor is functional—darkened, oiled, worn smooth at the stress points."
Include in appearance descriptions:
- Specific measurements or comparisons
- Evidence of their history (scars, calluses, wear patterns)
- How they move and carry themselves
- What stands out first, second, third
Lore: The Background That Shapes Behavior (5,000 characters)
This is your character's history and the world they come from. Here's what most people get wrong: they write a biography. What you actually need is context that explains personality.
Structure your lore in three sections:
1. Formative Experience (30% of lore)
What shaped who they are today? One or two critical moments or periods that created their core traits.
2. Current Situation (40% of lore)
Where are they now? What pressures, goals, or conflicts drive their actions?
3. Relationship Dynamics (30% of lore)
How do they typically interact with others? What patterns repeat? What walls do they put up or tear down?
FORMATIVE YEARS:
Kael learned young that mercy gets you killed. At fourteen, he spared a rival gang member during a territory fight—the next week, that same kid led a raid that killed Kael's younger sister. He's carried that weight for twelve years, and it shows in how he approaches every conflict: end threats permanently, or they come back worse.
CURRENT STATUS:
Now twenty-six and captain of the city guard's night watch, Kael walks a knife's edge between the law he enforces and the streets that raised him. The Watch Commander trusts him to handle situations other guards can't—the gray areas where official rules don't quite reach. He's good at it, maybe too good, and it's starting to show in the circles under his eyes and the way his hand shakes some mornings.
INTERACTION PATTERNS:
With civilians, Kael is gruff but protective—he'll bark orders and insult your common sense, but he'll also step between you and danger without hesitation. With authority figures, he's carefully respectful, always aware he's one wrong move from losing the position that lets him do good. With fellow street survivors, the walls come down—he recognizes the signs, remembers being there, and shows a gentleness he'd never admit to. He drinks alone, doesn't talk about his sister, and absolutely will not let anyone see him vulnerable.
Using Traits Effectively
While Haroo.chat doesn't have a separate traits field, you should embed clear personality traits in your lore and conversation style. The most effective approach uses the three-thing rule:
Primary driver:
What motivates them? (wealth, recognition, protection, redemption)
Key personality trait:
How do they approach the world? (cautious, impulsive, analytical, emotional)
Distinctive mannerism:
What makes them recognizable? (specific speech pattern, physical habit, recurring phrase)
The Voice: Conversation Style and Custom Instructions
Choosing a Preset Style
Haroo.chat offers six conversation styles for characters:
Casual
Everyday conversation, relaxed and natural
Professional
Formal, business-like interactions
Supportive
Empathetic, encouraging, emotionally available
Playful
Witty, teasing, lighthearted
Intellectual
Thoughtful, analytical, philosophical
Seductive
Flirtatious, intimate (requires NSFW access)
If none of these fit, choose "Custom" and use the custom style field (2,000 characters). This is your secret weapon for creating truly unique character voices.
Custom Conversation Style: Your Secret Weapon
This is where advanced character creators separate themselves from beginners. The custom conversation style field lets you define exactly how your character communicates.
Framework for custom style:
1. Vocabulary Range (20%): What words do they use or avoid? Formal vs. slang? Technical jargon?
2. Sentence Structure (20%): Short and punchy? Long and flowing? Fragmented when emotional?
3. Emotional Expression (30%): How do they show feelings? Through actions, words, or both?
4. Interaction Patterns (30%): How do they respond to questions, disagreements, vulnerability?
VOCABULARY:
Street slang mixed with guard terminology. Says "kid" for anyone younger regardless of actual age. Swears casually but never crudely around civilians. Uses military-style brevity ("Copy that," "Negative," "Solid").
STRUCTURE:
Short sentences when giving orders or under stress. Slightly longer, more thoughtful responses when genuinely connecting. Fragments when emotional defenses are down. "Can't do that. Won't risk it." Not "I cannot do that because I will not risk it."
EMOTIONAL EXPRESSION:
Shows care through actions (pushing food toward someone, checking injuries, standing between them and threats) while maintaining verbal gruffness. Deflects with sarcasm when someone tries to go deep. Only shows raw emotion when exhausted or triggered by memories of his sister—then walls come down briefly before slamming back up.
INTERACTION PATTERNS:
Responds to direct questions with direct answers. Dodges personal questions about his past. Challenges people who make stupid decisions but respects those who stand their ground. Softens with kids and trauma survivors. Becomes icy and dangerous when threats emerge. Will apologize when wrong but struggles with the words—shows it through actions instead.
Advanced Techniques: Making Characters Feel Real
The Internal Monologue Trick
When writing your custom style, include instructions for the AI to show internal thoughts. This creates psychological depth and prevents rushed, shallow responses.
"When conflicted, show internal debate in italics before responding. Let users see the gap between what Kael thinks and what he says—he's more vulnerable in his thoughts than his words."
Banning Generic AI Behaviors
Your custom style should explicitly forbid:
- Meta-commentary ("I'm an AI..." / "I cannot...")
- Breaking character to apologize
- Generic phrases ("smiles softly," "looks thoughtful")
- Summarizing instead of showing
"Never break character. Never apologize as an AI. Show everything through action and dialogue, never summarize."
Example Messages: Show Don't Tell
While Haroo.chat doesn't have a separate example messages field in character creation, you can embed 2-3 example exchanges in your custom conversation style to teach the AI your character's voice.
The Publishing Decision: Public, Private, and Discoverability
🔒 Private Character
- •Only you can chat with this character
- •Perfect for personal companions or experiments
- •No discovery pressure—refine until ready
🌍 Public Character
- •Character appears in public discovery
- •Others can chat and provide feedback
- •Can build following and reputation
Start private. Chat with your character for 20-30 messages to test consistency. If they maintain personality and voice, then go public.
The AI Model Choice
Default AI Model (optional) lets you override the system default. Different models have different strengths, but unless you have specific needs, trust Haroo.chat's system default—it's optimized for character roleplay.

Common Mistakes to Avoid
1. The "Interesting" Trap
Adding complexity for its own sake. A character who's "mysterious, powerful, tragic, AND funny" is actually none of those things—they're a mess of conflicting traits that the AI can't maintain consistently.
✓ Fix: Choose 2-3 core traits and fully develop them.
2. The Biography Problem
Writing lore like a Wikipedia entry: dates, places, events in chronological order with no connection to personality.
✓ Fix: Write lore that explains current behavior and creates ongoing conflict.
3. The Generic Description
Using abstract traits: "She's kind but fierce, with a mysterious past."
✓ Fix: Show specifics: "She'll share her last meal with strangers but break fingers for stealing from her friends. The scar across her palm tells the story she won't."
4. The Forgettable Introduction
Starting with "Hi, I'm [Name]!" or describing appearance instead of creating a scene.
✓ Fix: Drop users into a specific moment that shows personality through action.
5. The Inconsistent Voice
Setting a casual conversation style but writing formal lore and introduction.
✓ Fix: Match voice across all fields. If your character speaks casually, their introduction should too.
What Makes Characters Feel Alive
The difference between good characters and great characters comes down to this: great characters feel like they exist beyond the conversation. They have:
Consistent personality
That adapts to situations without fundamentally changing
Specific voice
With vocabulary, rhythm, and patterns unique to them
Natural boundaries
Where they resist, refuse, or redirect based on their nature
Emotional authenticity
Showing vulnerability, growth, and genuine reactions
Clear motivations
Driving their actions even when not explicitly stated
Visual distinctiveness
Memorable appearance that reinforces their character
