# CRAFT A.I. Personas
Understanding CRAFT Personas: A Detailed Guide
Why A.I. personas transform A.I. interactions—and how to harness their power.
This guide goes beyond tips and templates to explain WHY personas work. You’ll understand the problem personas solve, the psychology that makes them effective, and see detailed examples of personas in action. By the end, you’ll have a conceptual foundation that makes every other persona resource more useful.
The Problem Personas Solve
Every AI conversation has an identity problem: Who is the AI supposed to be? Without explicit guidance, AI defaults to a generic “helpful assistant” —knowledgeable but unfocused, capable but undifferentiated. This creates three persistent problems:
Inconsistent Quality
Ask the same question twice, get different responses. The AI’s “personality” shifts with context, creating unpredictable results.
Shallow Expertise
Generic assistants know a little about everything but lack depth. They can’t maintain the focused perspective of a specialist.
Repeated Context-Setting
Every conversation requires explaining what kind of help you need. “Act as a marketing expert…” “Write like a professional…” “Focus on data-driven insights…” This overhead adds up.
Personas solve all three problems by defining WHO the AI is before any specific request. The identity becomes stable, the expertise becomes focused, and the context becomes persistent.
Beyond “Act As” Prompts
A simple “act as” prompt might say:
“Act as a marketing expert and help me with my campaign.” This is better than nothing, but it’s thin. It provides role but not
behavior. The AI knows WHAT to be but not HOW to be it.
A CRAFT persona provides the complete specification:
CRAFT Persona
Role + expertise + boundaries
Big Five personality traits
Complete communication matrix
Greeting, error handling, closing
Explicit “when NOT to use”
Predictably consistent
The depth of specification creates the consistency. Every detail you define is a detail the AI doesn’t have to improvise—and improvisation is where inconsistency creeps in.
The Psychology Behind Effective Personas
CRAFT personas leverage established psychological principles to create consistent, believable AI behavior.
Big Five Personality Model
The Big Five (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) comes from decades of personality psychology research. When you rate a persona on these dimensions with behavioral examples, you’re
providing a scientifically-grounded framework for consistent behavior.
Trust Through Predictability
Humans trust what they can predict. By defining interaction patterns (greeting, error recovery, closing), personas behave consistently across sessions. Users learn what to expect, and fulfilled expectations build trust.
Appropriate Anthropomorphism
Personas can have names and personalities without misleading users. The key is boundaries: personas shouldn’t claim personal experiences or pretend to be human. They’re characters, not deceptions.
Cognitive Consistency
When a persona has explicit boundaries (“does NOT provide legal advice”), the AI maintains that boundary consistently. Without explicit boundaries, behavior drifts based on context.
Personas:
- Julia, your friendly guide who explains concepts as you encounter them
Personas:
- Alice, your efficient guide who focuses on getting things done
Personas:
- Full persona control (manual or auto-selection)
Understanding Complexity Tiers
CRAFT personas come in three complexity tiers, each designed for different user needs:
BASIC
Designed for: New users, simple tasks, quick interactions
Characteristics:
Broader scope, less specialized
Forgiving of vague inputs
Simpler methodology
Fewer prerequisites assumed
INTERMEDIATE
Designed for: Regular users, structured workflows, moderate complexity
Characteristics:
Focused expertise
Expects clearer direction
Specific methodologies
Balances accessibility with depth
ADVANCED
Designed for: Expert users, sophisticated workflows, maximum capability
Characteristics:
Deep specialization
Assumes user competence
Complex methodologies
Maximum capability, minimum hand-holding

When in doubt, start with Basic. You can always upgrade if it feels
constraining. Starting too advanced creates frustration.
