About Cortex - UX Copilot
Turn your browser into a conversion rate optimization (CRO) laboratory. Cortex is an AI-powered UX Copilot that helps product managers, developers, and UI/UX designers analyze website usability, visualize visitor behavior, and prototype layout fixes in real-time.
Directly integrated with your Cortex account, this extension injects a powerful floating overlay that lets you run comprehensive audits, view predictive heatmaps, and test design ideas on the fly without changing a single line of backend code.
KEY FEATURES:
📊 AI UX Usability Audits
Run instant audits to detect layout mismatches, text readability issues, and accessibility bottlenecks. Cortex extracts page elements and queries AI models to give you actionable feedback to boost conversions.
🔥 Predictive Attention Heatmaps
Visualize where your users are looking. Our predictive heatmap engine models human visual attention in real-time, letting you identify whether your Call-To-Action (CTA) buttons, hero sections, and key text are getting the exposure they deserve.
📉 Scroll Depth Tracking
Analyze user engagement and content placement. The interactive scroll overlay visually maps where users drop off, helping you determine the absolute best position for conversion-critical elements.
🧪 Instant A/B Testing & CSS Override Panel
Experiment with layouts directly in your browser. Select any element, modify its styles using the visual control panel, preview changes live, and copy the clean CSS overrides instantly to deploy in your production codebase or A/B testing tool.
📸 High-Resolution Full-Page Screenshots
Capture clean, complete screenshots of full webpages with a single hotkey (Alt+Shift+2 / Cmd+Shift+2) or click. Perfect for design comparison sheets, archive logs, and shareable audits.
HOW TO GET STARTED:
1. Install the extension.
2. Click the Cortex icon in your toolbar (or use the sidebar trigger on page load).
3. Connect your Cortex account to sync audits.
4. Open the sidebar on any webpage and start analyzing!
