Uxia vs Synthetic Users: UX testing or AI interviews?
Uxia and Synthetic Users both use AI-generated participants. The difference is what those participants are primarily asked to do. Uxia is centered on usability: testers navigate prototypes, sites, and product flows to complete a mission. Synthetic Users is more interview- and discovery-led: respondents discuss needs, behaviors, concepts, and messages. Choose Uxia when the digital experience is the research object.

RESEARCH-QUESTION ROUTER
The short answer: choose the research type
Start with Uxia when a participant needs to use, navigate, find, compare, or complete something in a digital experience. Start with Synthetic Users when a participant needs to explain, describe, react to, or discuss a need, idea, message, or market. For a study that moves from discovery to product validation, use interview-led research first, then task-based usability testing.
Choose based on what the participant must do
Both platforms overlap, but their center of gravity differs: Uxia is task- and interface-led; Synthetic Users is conversation-led.
Choose Uxia for product interaction
Use Uxia when the question is whether people can use an experience successfully. Test digital journeys, uncover friction, and improve task completion with behavioral evidence.

Choose Synthetic Users for research conversation
Use Synthetic Users when the question is what an audience would say, think, explain, or react to. Explore needs, concepts, messages, objections, and market language.
Best for interview-led discovery, concept and messaging feedback, and thematic synthesis.
Actions versus answers: the evidence is not the same
A usability study asks whether someone can move through an experience and achieve a goal. Uxia captures paths, interactions, expectations, think aloud, task friction, and the reasoning attached to each step.
An interview asks how a target audience describes its world. Synthetic Users surfaces needs, motivations, objections, attitudes, concept reactions, and repeated themes.

UXIA: TASK-BASED EVIDENCE
Continuous UX validation layer
Set up the task, observe interaction evidence, and review prioritized UX findings then repeat. Use our MCP to run testing from your agent of choice.
SYNTHETIC USERS: INTERVIEW-LED EVIDENCE
One-off testing
Launch qualitative interviews in minutes instead of weeks. A good solution to get deeper understanding of your audience before interviewing humans.

AI-POWERED UX RESEARCH PLATFORM
What is Uxia?
Uxia is an AI-powered UX research and usability-testing platform. Synthetic testers navigate prototypes, live products, websites, static designs, authenticated experiences, and complex digital flows while working toward a real user goal.

SYNTHETIC RESEARCH PLATFORM
What is Synthetic Users?
Synthetic Users is a user-research platform built around audience definition, interview planning, conversational feedback, and thematic synthesis.
How the workflows compare
Uxia begins with a digital experience and task. Synthetic Users begins with an audience, a research goal, and an interview plan. Their outputs reflect that difference.
Uxia workflow
STEP 1
Define the audience and mission
Describe who the testers represent and the goal they should complete.
STEP 2
Add the experience
Test a prototype, live website, product, or complex flow.
STEP 3
Run synthetic testers
AI testers explore the experience and report actions, expectations, and reasoning.
STEP 4
Review and iterate
Use prioritized issues to revise the design, rerun the study, or share the test with your own participants.
Synthetic Users workflow
STEP 1
Define the audience and study goal
Set the demographic, behavioral, psychographic, and professional characteristics that frame the conversation.
STEP 2
Plan the interview
Use dynamic, custom, or predefined interview approaches plus optional stimuli.
STEP 3
Run research conversations
Synthetic respondents answer, react, and maintain context across the discussion.
STEP 4
Synthesize themes and follow up
Review patterns, quotes, behaviors, sentiment, and recommendations; ask follow-up questions as needed.
Where Uxia is stronger
Usability is the core job
Start from the interface and user goal, then connect task outcomes to concrete UX friction and prioritized findings.
Interaction-first evidence
Inspect how testers navigate, what they expect, where they hesitate, and why a journey breaks down.
A clear human-validation path
Turn the same study into a shareable human test when a decision needs confirmation from people your team brings.
Fast task-based iteration
Rerun a mission across audience profiles or design revisions without turning each iteration into a new research operation.
Where Synthetic Users is stronger
Interview-led discovery, conversational depth, concept and messaging research.
Which research question comes first?
Choose Uxia when task completion, friction, expectations, or flow clarity matter most. Choose Synthetic Users when you are not evaluating a digital experience and the priority is needs, attitudes, objections, or the language an audience uses to describe a problem.
A practical two-layer research workflow
Use interview-led synthetic research to develop stronger hypotheses, then task-based usability testing to see whether the designed solution works in practice.
STEP 1
Map the problem through conversation
Use interview-led research to identify vocabulary, needs, objections, contexts, and competing behaviors.
STEP 2
Turn themes into testable product hypotheses
Translate the strongest themes into explicit questions the experience must answer.
STEP 3
Test the experience through interaction
Use Uxia to give synthetic testers a mission inside the prototype or product, then review friction and reasoning.
Final verdict: Uxia for task-based usability; Synthetic Users for interview-led discovery
Choose Uxia when the main decision is whether a digital experience works for the user. Choose Synthetic Users when the main decision is what an audience would think in a research conversation. Use conversations to develop hypotheses, task sessions to test the experience, and people to validate the highest-risk decisions.
