SyntheticUsers

Catch structural UI flaws with custom AI personas inside FigmaOverviewStop guessing whether your layouts work or waiting weeks for user testing. Synthetic Users isn’t a generic chatbot wrapper—it’s a rigorous UX simulation engine that drops custom personas straight into your canvas to stress-test information hierarchies, catch accessibility traps, and expose cognitive overload before you write a line of code.

Why It's DifferentMulti-Persona Conflict Testing: Test a single design against conflicting user archetypes simultaneously (e.g., an impatient executive who hates clutter alongside a user with deuteranopia navigating pure red/green charts).

Custom Persona Engine: Build your exact user panel using strict, plain-English behavioral rules and domain constraints—moving far beyond cookie-cutter AI profiles.

Canvas-Native Diagnostics: Pinpoint invisible friction and drop actionable diagnostic notes directly onto your Figma frames the second you finish designing.

Key FeaturesInstant Frame Targeting: Select any screen or interaction flow in your file with zero exports or tool-switching.

Context-Aware Prompts: Run targeted heuristic checks on conversion blockers, pricing readability, and drop-off points.

Persistent Panel: Build your panel once and reuse your custom user personas across every project in your workspace.

Pro Tips for High-Signal Feedback1. Isolate One Constraint: Ask about a single metric or interaction per run ("What causes a drop-off on the top KPI row?") to avoid diluted, generic responses.

2. Ground the Persona: Give your AI explicit real-world context ("As a busy enterprise buyer scanning this in 5 seconds...") to anchor its perspective.

3. Target Invisible Flaws: Use prompts to hunt down accessibility failures, conflicting currency formats, and buried alerts that eye-tests miss.
