The Probe Inspector

Last updated
March 23, 2026

The Probe Inspector is the main interface for reviewing probe results. It brings together the canvas, findings, version history, and view controls in a single workspace.

The Probe Summary

After a probe runs, the Probe Inspector opens with the Probe Summary. This gives you an overview of what was detected — how many findings were found across Properties, Spacing, and Unverified, and how that compares to the previous run if one exists.

The canvas

The canvas is the central area of the Probe Inspector. It displays the visual comparison between the Figma design and the live webpage, with markers showing where findings are located.

Selecting a marker focuses the canvas on that area and opens the corresponding annotation card.

The canvas updates when you:

  • select a finding in the Findings panel
  • switch view modes
  • switch between probe versions

View controls

View controls are located in the top toolbar. They let you switch between Web, Figma, Split, Overlay, and Diff view modes. Switching view modes changes how the comparison is displayed on the canvas — it does not affect findings or probe versions.

The Findings panel

The Findings panel lists all findings for the current probe version, organised into three sections:

  • Properties — verified differences in size, typography, style, and content. You can filter by category to focus on specific types of differences.
  • Spacing — verified differences in spacing between elements. A tolerance filter lets you control which deviations are surfaced: Pixel-perfect, Standard, or Flexible.
  • Unverified — elements the system detected but couldn't fully map to the design.

Selecting a finding in the panel highlights the corresponding marker on the canvas and opens its annotation card.

The Versions panel

The Versions panel shows the history of probe runs. Selecting a version updates the canvas, markers, and findings to reflect that snapshot.

When viewing a historical version, a status indicator in the toolbar lets you return to the latest version at any time.

How everything works together

The Probe Inspector keeps all its components in sync:

  • selecting a finding updates the canvas and opens its annotation card
  • selecting a marker updates the Findings panel
  • switching versions updates everything — canvas, markers, findings, and annotation cards
  • switching view modes affects the canvas only

What the Probe Inspector is not

The Probe Inspector is for visual review only. It does not manage tasks, replace ticketing tools, or perform functional or accessibility testing.
