Skip the manual review — let AI take the first pass

From instant change summaries to running the whole workflow from your editor, Diffy's AI features cut out the busywork.

AI-generated diff summaries

  • Groups every change by type — layout, content, style
  • Prioritizes by impact, so a shifted header outranks a new testimonial
  • Skim the summary in seconds instead of opening every screenshot pair
AI-generated summary of visual changes, grouping the contact-us and give pages' critical layout issues above a minor language-link addition

Run Diffy straight from Claude

  • Our skills plugin lets Claude screenshot your local dev environment and compare it before/after a code change, or against staging and production
  • Just ask in plain English — no need to open the Diffy UI
  • Claude pulls the results back into your conversation, so it sees exactly what changed

Use cases

Diffy fits wherever visual accuracy matters.

Compare any environments

Catch regressions before they reach users by comparing production against staging, dev, or any other environment side by side.

Regular monitoring

Schedule automated screenshot comparisons on a cadence so unexpected changes — broken layouts, missing content, style drift — are flagged the moment they appear.

Screenshots vs. Figma designs

Verify that implemented pages match approved designs by comparing live screenshots directly against exported Figma frames.

Diffy supports your team with an extra set of eyes

So your colleagues do not need to check pages manually.

Less time needed for review

  • Same change identified across multiple screenshots
  • Vertical shifts detection
