Overview
Analyzes data-heavy dashboards and visualizes cognitive load using structural and interaction metrics.
Cognitive Load Visualizer helps designers, developers, and researchers understand how mentally demanding a webpage is. It analyzes any site in real time and generates a science-backed cognitive-load score based on visual complexity, interaction density, and layout structure. A heatmap highlights the areas that require the most mental effort, making usability issues easy to spot before they frustrate users. Key Features • Instant Cognitive Load Score: Clear 0–100 rating based on cognitive science principles. • Real-time UI Analysis: Measures DOM depth, layout complexity, and interactive element density. • Heatmap Overlay: Visualizes high-load regions at a glance. • CLT-Based Evaluation: Grounded in Cognitive Load Theory, visual search research, and working-memory limits. • One-Click Re-Analysis: Quickly evaluate design changes or updates. • Privacy-Preserving: All processing happens locally—no data is sent or stored anywhere. Why It Matters Cognitive overload is a major source of user frustration. This tool helps you identify: • Confusing layouts • Cluttered or dense interfaces • Unnecessary interaction complexity • Poor visual grouping or hierarchy • Split-attention effects Ideal for UX designers, developers, product teams, accessibility reviewers, and HCI students. How It Works 1. Open any webpage 2. Click the extension 3. View the cognitive-load score and metrics 4. Optionally enable the heatmap overlay 5. Re-analyze as you iterate on designs Evaluates: DOM depth, interactive element density, layout fragmentation, visual grouping, and attention-switching demands. Privacy No data is collected, transmitted, or stored. All analysis runs entirely on your device.
