Smarter Visual Testing with BrowserStack AI

Eliminates false positives, allowing teams to review meaningful visual changes and release faster with confidence.

Visual testing powered by BrowserStack AI

Visual Review Agent

Reduces visual noise, highlights meaningful visual inconsistencies, and streamlines visual reviews for faster, more focused approvals.

Noise reduction

Filters out pixel-level noise to surface only meaningful visual differences.

Highlight key changes

Draws bounding boxes & provides summaries for impactful visual changes.

Faster Visual Reviews

Reduces review time by up to 3× with focused insights and clear summaries.

Visual AI Engine

Visual AI Engine enhances image comparison with advanced algorithms, improving accuracy and speed by detecting meaningful changes and optimizing performance.

Layout Testing

Detects layout shifts by tracking the relative position of elements to catch broken layouts early.

Visual noise

Suppresses false positives from dynamic banners, animations, anti-aliasing, and flaky text rendering.

Intelli Ignore

Filter out minor webpage changes and focus only on user-relevant visual differences for enhanced stability.

FAQs

Visual AI Engine is the base algorithm that powers Percy to automate & scale visual testing faster. It houses some of the flagship features like –

  • OCR analysis avoids flagging minor text or font shifts.
  • Shift detection isolates changes from new page elements without flagging the entire layout.
  • In relaxed mode, edge detection ignores tiny pixel, color, or thickness changes in shapes and images, ensuring only meaningful differences are highlighted.
  • Intelli ignore – automatically detects and excludes dynamic or irrelevant visual changes from diffs, reducing false positives.

 

Navigate to the Build review screen of your Percy project and toggle the AI Beta button. Once enabled, all snapshots in the project will be reviewed using the Visual Review Agent.

Teams using the agent report up to 3× faster reviews with improved focus and fewer manual steps.

Traditional visual testing tools highlight every pixel change, often creating visual noise that slows down reviews. The Visual Review Agent replaces this with smart highlights—drawing bounding boxes only around meaningful changes, removing red pixel noise, and providing clear, human-readable summaries of what changed. This makes reviews cleaner, faster, and easier to act on.

The Visual Review Agent supports snapshots up to 4500 pixels in height, ensuring fast, accurate reviews for the vast majority of web pages. For taller pages, Percy automatically uses its standard visual comparison to maintain complete coverage.

Yes, the Visual Review Agent works across all browsers and devices supported by Percy, ensuring consistent visual testing coverage.
