Compare text in Blocks, Fluid and Unified layouts. Quickly navigate and search through the most readable diff you've ever seen.

  • Custom comparison engine for insanely readable results
  • Seamlessly switch between three different layouts
  • Pick your font and color scheme, with or without wrapping
  • Powerful search and navigation features
  • Did we mention it's blazing fast?

Versatile

Compare your files in three different layouts, use instant search to find matches in one or both files, and use your keyboard's arrow keys to quickly jump from change to change. There are no distractions but tons of useful features.

Readable

Kaleidoscope finds the most readable way to express changes, instead of simply showing what's easiest for a computer to parse. Our 100% custom comparison engine goes the extra mile to give you the clearest possible overview.

 

Spot the Differences - Image Scope

  Four Layouts

Spot the smallest retouch, that 2 pixel nudge and the slightest color change in a heartbeat.

Incredibly Fast

One-Up

  • Perfect for photographers, retouchers and designers
  • Did we mention it's super snappy?

Responsive

Simply put, the image scope is really fast. Scrolling and zooming is always responsive, whether you use multi-touch gestures or your mouse and keyboard shortcuts. Try it once and you'll wonder why you ever settled for less.

Spot On

The human eye is really good at spotting differences, but sometimes it can use a little help. Each layout aids the eye in a different way, to help you quickly spot anything, from the smallest retouch to image-wide color changes.
