Select your persona, choose what to test, and run a simulation for deep persona-driven feedback.

Pro tips

🔍
Be hyper-specific
"35-year-old SaaS marketer in London" beats "marketing professional." Specificity drives more accurate, actionable feedback.
👥
Create 2–3 contrasting personas
Test through a tech-savvy early adopter and a cautious late adopter to catch weak spots in your content.
📋
Ground personas in real data
Pull frustrations from real customer reviews, support tickets or sales call notes for maximum realism.
Test Everything

Simple 3-Step Process

From install to insight in minutes

No user recruitment, no survey design, no waiting weeks for results. Purple Builder simulates your users instantly.

1
🧩
Install the Chrome Extension

Click the Purple Builder icon in your browser. It opens as a floating panel without navigating away, refreshing your page, or losing your scroll position.

2
🎭
Choose or Create an AI Persona

Search using natural language — "VC investor in New York" or "young ecommerce founder". AI suggests the best-fit personas for your specific page and domain, or create your own.

3
🚀
Run Simulation & Read the Report

A countdown (3, 2, 1, Go!) triggers the AI cursor. Watch it navigate your page in real time, then receive a full dashboard report with video replay and emotional insights.

Chrome Extension

Your product's user lab,
right in the browser

Everything you need to discover, configure and simulate AI user personas — without leaving the page you're testing.

🔍
Natural Language Persona Search

Type descriptions like "budget-conscious parent" or "senior B2B buyer" and AI returns the closest matching personas instantly.

✨
AI-Suggested Personas

Purple Builder reads your domain and page type, then recommends the most relevant personas for that context — no setup needed.

🎨
Custom Persona Builder

Create personas from scratch with a name, image, industry, buying power, decision speed, trust level, and behavioral parameters.

🎯
Intent Configuration

Define what your persona is trying to achieve on this website. AI generates suggested intents as chips you can select and combine.

🗂️
Smart Filters

Filter personas by Role, Industry, Location, Age, Buying Power, and Behavioral traits to zero in on exactly who matters to your business.

⚡
One-Click Simulation Start

Select a persona, add an intent, and hit "Start running this Persona". That's it. The simulation begins in three seconds.

Real-Time Simulation Engine

Watch your user think, hesitate and decide

A second AI-controlled cursor appears on screen, moving and reacting exactly as your target persona would — not a script, real AI cognition.

🖱️
Dual Cursor System

Your real cursor and the AI persona cursor coexist. Track X/Y coordinates, velocity, hover duration and direction changes in real time.

🧠
DOM Interpretation Engine

AI scans the visible viewport, categorises every element (Hero, CTA, Pricing Table, Feature List…) and calculates visual attention priority before moving.

⏸️
Pause on Confusion

When the persona encounters confusion or a decision point, the simulation pauses. You see the question, the hesitation — and can choose to approve or skip the action.

💬
Live Feedback Stream

Real-time commentary appears inside the extension as the persona browses — instant reactions to your copy, layout, CTAs and pricing.

🎬
Countdown Launch (3, 2, 1, Go)

A cinematic countdown loads the persona, intent, and metric components, then kicks off DOM scanning before the cursor takes over.

🗄️
Full Event Storage

Every event is stored — timestamp, DOM element, event type, cursor coordinates, emotional snapshot, persona feedback, navigation sequence position.

Emotional Intelligence

9 emotions tracked in real time

Every DOM interaction updates your persona's emotional state. Watch metrics shift as they scroll through your hero, read your pricing, or hit a confusing CTA.

LIVE FEEDBACK
"The pricing section is interesting but I don't immediately see the value prop for my team size. I'd want to compare plans before clicking."
Navigation Intelligence

7 behavioural signals per session

Know exactly where your users look first, what they skip, how deep they scroll, and how many times they revisit an element before deciding.

👁️
Eye-Priority Order

AI ranks every DOM element by visual attention — based on viewport position, element size, text weight, colour contrast and persona intent relevance.

📍
Cursor Coordinates

Every simulation cursor movement logs X/Y position, velocity, hover duration and direction change — a full heatmap of persona attention.

🔢
DOM Entry Sequence

Records the exact order in which elements are entered — revealing whether users follow your intended reading flow or jump around.

⏭️
Skipped Elements

Detects which sections your persona completely ignores — often the most valuable signal for layout and copy improvements.

⏱️
Time Spent per Element

Timestamped dwell data for every DOM element. See which sections hold attention and which lose it in under two seconds.

🔁
Re-entry Count

Tracks how many times the persona revisits a specific element — a strong signal of confusion, indecision or deep interest.

📜
Scroll Depth Percentage

Records the lowest DOM element reached, showing exactly how far down the page your persona scrolled before dropping off or converting.

Dashboard & Reports

Insights you can act on immediately

Every simulation produces a rich, interactive report — not a wall of data, but a clear story of what your users felt, saw, and did.

🎥
Video Replay

Watch the full simulation back like a screen recording. See the cursor path, hover pauses and scroll behaviour exactly as it happened.

📊
Realtime Event Log

Every event timestamped and tagged — DOM element entered, cursor coordinate, emotional snapshot, feedback comment.

🔄
Bidirectional Optimisation

The dashboard opens a two-way dialogue — see what the persona suggests changing, approve or skip, and iterate in real time.

Why Purple Builder

The way you test products is broken

Traditional user research is slow, expensive and often wrong. Purple Builder gives you the same depth of insight in minutes, not months.

Instant Feedback Loop

Make a change to your landing page, run a new simulation in 3 seconds, and see exactly how the update shifts your persona's emotions and decisions. No waiting, no scheduling.

🌍
Any Persona, Any Market

Test your SaaS pricing page with a CFO persona, your e-commerce checkout with a price-sensitive parent, and your landing page with a first-time buyer — all in one afternoon.

🧬
Persona Depth Beyond Demographics

Every persona carries buying power, decision speed, curiosity level, trust baseline and industry context — not just age and gender. Simulations reflect real cognitive behaviour.

🔒
No Real Users Required

Early-stage founders can validate ideas before they have customers. Established teams can test sensitive changes without exposing real users to broken experiments.

Tangible Business Impact

What changes when you simulate before you ship

Every product decision carries risk. Purple Builder eliminates the guesswork and gives your team a data-backed reason to act — or not act.

"We ran a simulation before our landing page redesign. The confusion spike on the pricing table saved us from a $40k dev sprint that wouldn't have worked."

Priya S.
Head of Growth, B2B SaaS
★★★★★

"I didn't have beta users yet. Purple Builder let me test my checkout flow with a 'budget-conscious first-time buyer' and I found three drop-off points in one session."

👨‍💻
Marcus T.
Founder, E-commerce
★★★★★

"The emotional metrics dashboard changed how we talk about product decisions internally. We went from 'we think users feel X' to 'here's the data showing trust at 74%'."
