Visual AI – AI-Powered Visual Change Detection Like Humans Do

LambdaTest SmartUI introduces a Visual AI agent that revolutionizes visual regression testing by simulating human perception. Instead of just highlighting every pixel difference, this AI-powered feature identifies and summarizes only the meaningful, human-relevant changes between your baseline and captured screenshots. This allows you to instantly focus on significant UI shifts and understand the context of the changes without getting lost in minor, irrelevant noise.

What Problems Does SmartUI Visual Agent Solve?

Traditional pixel-to-pixel comparison can be noisy and time-consuming. SmartUI Visual Agent eliminates the guesswork by providing context-aware, intelligent analysis.

Problem	SmartUI Visual Agent Solution
Pixel diffs are cluttered with noise from anti-aliasing or rendering glitches.	The AI agent filters out irrelevant diffs and only highlights changes a human user would notice.
It's hard to understand the scope or meaning of a change from a simple highlighted area.	Get a plain-English summary that explains the entire change in context.
Reviewing hundreds of minor visual differences is slow and inefficient.	Focus your attention only on significant UI and UX regressions that impact the user experience.

How to Use SmartUI Visual Agent

Step 1: Activate Visual AI Mode

Navigate to any SmartUI comparison build. In the toolbar above the screenshots, locate and click the Visual AI toggle. This activates the "Human Intelligence AI Agent."

Step 2: Investigate AI-Detected Differences

Once Visual AI is active, the system automatically draws boxes around what it has identified as significant visual changes on the "Captured" screenshot. You can then interact with these boxes to learn more.

User Interaction	Visual Feedback
Default View	Boxes are drawn around each meaningful visual difference the AI has detected.
Hover on a diff box	The box under your cursor highlights slightly, indicating it is interactive.
Click a diff box	The box turns red to confirm your selection, and a floating summary panel appears with a description of the change.

Step 3: Understand the AI-Generated Summary

When you click on a diff box, a panel appears with a concise, human-readable explanation of the change. This summary describes the full scope of the difference, allowing for quick recognition and understanding. For example, it might summarize a complex visual change as "Content Grid Replaced with Placeholders."

Provide Feedback

All members can give feedback on AI-generated differences and summaries. Following are the available feedback options:

• Thumbs up/down.
• Comment (optional): Enter up to 120 characters. This option is only available when a thumbs-up or thumbs-down is given.

Things to Keep in Mind

• Visual AI Agent is currently available for comparisons with vertical lengths under 5000px.
• If the Visual AI agent is active and you open the RCA panel, the panel will still display all differences from the standard Smart RCA comparison.

Visual AI Agent can make mistakes. Please visually verify the results.
