AI synthetic user testing platform
Test Figma prototypes with AI personas before recruiting users.
Paste a prototype link, define the task, and let a synthetic panel reveal where users hesitate, misread, click, and abandon the flow.

Report output
From prototype uncertainty to a ranked usability plan.
Each run turns hundreds of synthetic task attempts into evidence your product, design, and growth teams can review together.
Prototype import
Paste a Figma link, test a public URL, or upload a screenshot set for early-stage flows.
Persona generator
Create synthetic users with goals, objections, device context, market fit, and research constraints.
Task-flow testing
Ask 50 to 500 AI users to complete a task and capture their paths, pauses, and drop-offs.
Sentiment feedback
Read natural-language reactions that explain confusion, trust, motivation, and hesitation.
Heatmaps and click maps
Visualize where attention went, what got clicked, and which elements created false affordances.
Priority report
Get the top usability issues, severity, likely conversion impact, and recommended UI changes.
Persona fidelity
Make research assumptions explicit before they become roadmap guesses.
SyntheticUser Lab creates a balanced panel of AI personas with motivations, objections, accessibility needs, prior knowledge, and device context. Each persona then attempts the same task so the report shows where behavior diverges by segment.

Designed for fast prototype decisions, not vanity feedback.
The workflow keeps every run tied to a task, a user segment, and a decision your team can make after the report.
Import
Bring in a Figma link, URL, or screenshots and define the exact user task.
Simulate
Generate AI personas and run task attempts with path, language, and attention tracking.
Prioritize
Review the top usability issues, likely conversion impact, and recommended UI changes.
Rerun
Test the revised prototype and compare completion, confidence, and drop-off movement.

Before you run it
Useful guardrails for synthetic research.
Should this replace real user interviews?
No. Use it to catch obvious prototype friction, prepare sharper research questions, and compare options quickly. High-stakes product, medical, legal, financial, or regulated decisions still need appropriate human validation.
Can I test a Figma prototype that is not public?
The first version supports link-based and screenshot-based review patterns. For private prototypes, screenshots or controlled project access are safer than broad public links.
What happens after checkout?
Payment returns to the homepage after NOWPayments completes or redirects the invoice. If a crypto network is still confirming, support can reconcile the order with the invoice identifier.
