Test Like Real People

Every user thinks differently. A 65-year-old retiree, an impatient teenager, and someone with motor tremors will each experience your signup flow in fundamentally different ways.

Stop testing with one mindset. CBrowser lets you simulate dozens of cognitive profiles so you see what each user type actually encounters.

Create a Persona

26 Cognitive Traits

Each persona is defined by a unique combination of these research-backed traits. Every trait is a value from 0 to 1 that shapes how the simulated user perceives, decides, and interacts.

patience

How long the user waits before giving up

riskTolerance

Willingness to click unfamiliar UI

comprehension

Ability to understand complex text

persistence

Obstacles pushed through before quitting

curiosity

Drive to explore beyond the obvious path

workingMemory

Capacity to hold multiple pieces of info

readingTendency

How thoroughly text is read vs. scanned

resilience

Recovery speed after errors or confusion

selfEfficacy

Confidence in completing digital tasks

satisficing

Picks first "good enough" option vs. optimizing

trustCalibration

How quickly the user trusts a site

interruptRecovery

Resuming tasks after distraction

informationForaging

Skill at following information scent

changeBlindness

Likelihood of missing UI changes

anchoringBias

First number seen influences decisions

timeHorizon

Instant results vs. investing in setup

attributionStyle

Blames self or site when things fail

metacognitivePlanning

Planning multi-step tasks ahead

proceduralFluency

Speed with familiar UI patterns

transferLearning

Applying knowledge from other sites

authoritySensitivity

Responsiveness to trust signals

emotionalContagion

How site tone affects user mood

fearOfMissingOut

Susceptibility to urgency signals

socialProofSensitivity

Influence of reviews and ratings

mentalModelRigidity

Difficulty with unexpected UX patterns

siteFamiliarity

Prior experience with this specific site

Built-in Personas

Start with these pre-calibrated profiles. Each one is built from real behavioral research and ready to test your site immediately.

first-timer

Has never visited the site. Cautious, exploratory, easily confused by jargon.

power-user

Knows every shortcut. Impatient with slow flows, skips instructions.

elderly-user

Careful and methodical. Prefers familiar patterns, reads everything.

mobile-user

One-handed, distracted, on cellular data. Low patience for load times.

impatient-user

Gives you 3 seconds. Bounces at the first sign of friction.

cognitive-adhd

Easily distracted, impulsive clicks, struggles with long forms.

motor-impairment-tremor

Involuntary hand movement. Needs large click targets and forgiving interactions.

low-vision-magnified

Uses 200% zoom. Relies on high contrast and structured headings.

Plus 13 more personas covering screen reader users, color blindness, dyslexia, anxiety, and other accessibility profiles.

Create Your Own

Built-in personas are a starting point. Your users are unique. Two ways to build a custom cognitive profile that matches your actual audience.

Natural Language Description

Describe your user in plain English. The AI generates the full 26-trait cognitive profile automatically.

"A budget-conscious parent
shopping on their phone during
a lunch break. Short on time,
comparison-shops heavily, and
won't buy without reviews."

CBrowser maps the description to trait values, sets patience low, socialProofSensitivity high, and satisficing to 0.8.

Questionnaire

Answer a series of behavioral questions and let the system calibrate trait values based on your responses.

Q1:How long does this user wait before leaving a slow page?

Q2:Do they read error messages or just retry?

Q3:How much do reviews and social proof influence their decisions?

Each answer calibrates multiple traits simultaneously, producing a statistically coherent profile.

10 Motivational Values

Traits describe how a user behaves. Values describe why. Based on Schwartz's Theory of Basic Human Values, these 10 motivational values modulate how personas interpret content and make decisions.

Achievement

Driven by personal success and demonstrating competence

Benevolence

Motivated by care for people they know personally

Conformity

Acts within social expectations, avoids disruption

Hedonism

Seeks pleasure, enjoyment, and sensory satisfaction

Power

Values social status, prestige, and control over resources

Security

Prioritizes safety, stability, and predictability

Self-Direction

Independent thinking, creativity, freedom to explore

Stimulation

Drawn to excitement, novelty, and new challenges

Tradition

Respects customs, heritage, and established ways

Universalism

Cares about social justice, equality, and the environment

A user who values Security will hesitate at unfamiliar payment flows. A user who values Stimulation will click every new feature announcement. Values shape the journey without changing the interface.

What You Learn

After running a persona test, you get quantified results that tell you exactly where each user type struggles and what to fix.

CTC Cost Per Layer

Cognitive Transport Cost across 6 layers: readability, visual complexity, interaction friction, decision load, trust burden, and motor demand.

Abandonment Risk

Probability this persona gives up before completing the goal, based on patience and friction exposure.

Bottleneck Identification

The exact step and element where the persona struggles most. Pinpoints what to fix first.

Barrier Detection

Accessibility and usability barriers specific to this persona. A tremor user and a screen reader user hit different walls.

Empathy Score

Overall measure of how well your site accommodates this persona. Higher means lower friction.

Create Your First Persona

Describe a user in plain English and get a full cognitive profile in seconds. Then run a journey and see your site through their eyes.
