Realistic Friction
Models the micro-moments of hesitation, second-guessing, and navigation errors that real humans experience daily.
Behavioral Simulation
Modeling the messy reality of human action.
Thymos is Aetherya's proprietary behavioral layer that models human factor variables—such as hesitation, emotional drift, attention limits, and cognitive load—ensuring your simulations behave exactly like real, imperfect users.
The Human Factor
Cortex understands the task. Thymos models the human response.
Most AI agents behave like ideal users: rational, patient, literal, and consistent. Real users are not like that. They get frustrated, misread text, second-guess, and abandon flows. Thymos models these messy variables so you can build better journeys.
Built for the way people actually behave
They hesitate. They skim. They misread. They get tired. They change their mind.
Thymos is Aetherya's proprietary behavioral layer for simulating those human factors across product journeys, ads, landing pages, and audience conversations. It is the layer that makes simulations feel real—because it models how real people actually execute decisions.
PROPRIETARY ENGINE
BEHAVIORAL ENTROPY
Cognitive Core
What Thymos Models
01Hesitation & Uncertainty
Thymos models the moments users pause, second-guess, or abandon a flow entirely—capturing the friction that pure logic never sees.
02Emotional Response
From delight to frustration, Thymos simulates how emotional state shapes every click, scroll, and decision a user makes.
03Attention Drift
Real users don't read everything. Thymos models how attention wanders, what gets skimmed, and what gets missed altogether.
04Cognitive Load
Thymos tracks how much mental effort a product demands—and when that load tips users toward confusion, shortcuts, or exit.
05Trust & Friction Signals
Every UI element either builds or erodes confidence. Thymos surfaces the subtle signals that push users toward or away from conversion.
06Misinterpretation & Recovery
Users misread labels, miss CTAs, and take wrong turns. Thymos simulates those errors and tracks how—or whether—they recover.
07Persona-Specific Decision Patterns
Different people make decisions differently. Thymos adapts its behavioral output to match the specific psychology of any persona you define.
System design
More realistic because it models real human reactions.
Emotional Adaptability
Simulates how delight, confusion, or growing frustration directly scales a user's likelihood to complete a transaction or exit.
Cognitive Load Thresholds
Tracks visual complexity and informational density, predicting exactly when visual fatigue causes a user to abandon a flow.
Integration
How Thymos operates within Aetherya.
- 01Embedded CoreThymos operates directly within Aetherya's simulation runner, serving as the behavioral multiplier behind every synthetic persona.
- 02Behavioral-FirstOptimized specifically for realistic action-paths, visual scanning, and decision friction—never generic chatbot dialogues.
- 03Privacy-by-DesignSimulates actual audience psychographics without cookie tracking, recording, or infringing on actual consumer privacy.
Platform application
What it powers.
Thymos runs deeply integrated throughout the Aetherya platform, scaling behavior-realism across core pipelines.
UX Audits
Deep behavioral analysis mapping exactly where and why actual users hesitate or abandon.
Audience Chat
Enables synthetic personas to converse with cognitive friction, hesitation, and emotional reality.
Ad Lab
Simulates actual emotional response to creative assets and copy before spending media budget.
Journey Testing
Simulates non-linear, multi-step user navigation, locating error recoveries and dead ends.
Conversion Analysis
Diagnoses the precise point where mental load outweighs conversion value for targeted groups.
Simulation Realism
Behavior grounded in reality.
Modeling human complexity
Thymos models are trained to capture the complex, non-linear ways people experience interfaces—focusing on hesitation times, reading velocities, and confusion thresholds rather than perfect, automated traversal.
Synthetic, private calibration
By operating with high-fidelity synthetic personas, Thymos yields valuable behavioral insights without requiring invasive tracking, cookies, or video sessions of actual humans.
