Sketchhat releases DesignDiff: model-driven visual diff viewer that explains changes semantically

DesignDiff analyzes two design snapshots and produces a list of semantic changes like "button color token switched from primary-600 to accent-500" or "navigation collapsed into a hamburger at 768px." The model also ranks changes by user impact and suggests rollback patches for accidental regressions.

The tool integrates into CI pipelines for design systems and generates summaries suitable for product managers and developers, reducing misunderstanding during handoffs. It can also flag potential accessibility regressions and propose fixes like contrast adjustments.

Sketchhat added a feedback loop: reviewers can mark explanations as accurate or not, and the model adapts its phrasing and prioritization over time. Teams report faster cross-discipline reviews and fewer ambiguous PR comments when using DesignDiff in their workflows.
