Customization Strategies
Start With Templates
Don’t build from scratch. Start with existing characters that match your general preference, then customize from there.
Browse Bonza.Chat’s character types for starting points.
Define Core Traits First
Begin with fundamental personality before adding details:
- Energy level: High or low?
- Emotional style: Expressive or reserved?
- Communication: Playful or serious?
- Relationship approach: Initiating or responsive?
Use Specific Examples
Instead of “friendly,” try “greets you enthusiastically with questions about your day.”
Instead of “smart,” try “loves discussing philosophy and makes references to books she’s read.”
Specific examples communicate more than general traits.
Consider Interaction Patterns
Think about how conversations should feel:
- Does she ask lots of questions?
- Does she share about herself unprompted?
- Does she tease or stay sincere?
- Does she initiate romantic moments?
Plan for Development
Leave room for the relationship to grow. Over-specifying everything can make interactions feel scripted.

Pre-Built vs. Custom Characters
Pre-Built Characters
Pros:
- Instant quality
- Optimized personalities
- Consistent behavior
- No setup required
Cons:
- Less personalization
- Limited to available options
- Not uniquely yours
Custom Characters
Pros:
- Exactly what you want
- Unique to you
- Full control
- Can match specific fantasies
Cons:
- Requires effort
- Quality depends on your input
- May need iteration
The Best Approach
Start with pre-built characters to understand what works. Create custom characters once you know your preferences.
Bonza.Chat lets you do both—browse existing characters or create your own.
Customization Tips
Be Specific About What Matters
Focus customization on elements that affect your experience most. Personality and communication style matter more than elaborate backstory.
Test and Iterate
Your first custom character won’t be perfect. Have conversations, note what works, refine, repeat.
Don’t Over-Specify
Some mystery and natural development creates better relationships than scripting everything.
Match Platform to Vision
If your ideal character involves romantic content, use platforms that allow it. Character.AI’s filters will block customization that matters.
Use Memory as Customization
Platforms with strong memory let characters learn your preferences over time. Share what you like; she’ll adapt.
