Frequently Asked Questions

How detailed should my customization be?

As detailed as needed for consistency. Start with basics, add depth as you discover what matters.

Can I change customization later?

Usually yes, though some changes require starting fresh.

Does more customization mean better experience?

Not necessarily. Well-considered basic customization often outperforms complex but unfocused specification.

How do I avoid generic characters?

Specific details, unique quirks, and defined perspectives create distinctiveness.

Can I make my AI girlfriend like a specific person?

Ethically questionable with real people. Creating original characters inspired by traits is better approach.

Why doesn't my customization always work?

AI has inherent variability. Perfect control isn't possible, but good customization improves consistency.

Should I use premade characters or create my own?

Both valid. Premade for quick start, custom for specific vision.

How do I make personality feel authentic?

Consistency, unique details, and natural contradictions (humans aren't one-dimensional).
