Stop playing spot-the-difference

Autodetect changes between two versions of a UI design

How it works

How it works?

Step One

Edit your UI design mockup, wireframe or hi-fidelity prototype

Step Two

Publish this new version

There is no step three

ImmutableDoc auto detects the changes between the versions of your UI design and then lists these changes in an organized hierarchical structure to help designers and developers collaborate efficiently in implementing these changes.

It automatically publishes the changelog to your team mates on their registered channel(Email or Slack).

A new version of the design document is commited to your linked source code repository and a task list is created in your issue tracker for your front end engineers.


Every change is logged

No modification to the design goes unobserved. From a single bit color change to a displacement of single pixel, each modification is logged.

Front end developers don't have to play spot the difference

Whenever a new version of the design document is published, developers receive a precise list of all the components that need to be modified on various screens/pages

Always in sync with your issue tracker

Everytime the design team changes the mockup, the issue tracker is updated automatically which keeps the front end engineers' task list current.

Get notified when a design is modified

Publish a new version and ImmutableDoc will inform all the stake holders automatically. No more missed memos!
