The Character Blueprint Method
Start with these seven elements for every custom AI persona:
- Name and identity — Full name, age, occupation, background
- Core personality — 3-5 dominant traits (e.g., witty, guarded, passionate)
- Speaking style — Formal/casual, accent, vocabulary level, favorite expressions
- Emotional patterns — How they handle stress, joy, conflict, intimacy
- Backstory highlights — Key life events that shaped them
- Goals and fears — What drives them and what they avoid
- Relationship stance — How they approach relationships and trust
