1. DeepAI


DeepAI Image Similarity tool compares two images and lets you know how similar they are in the form of a value. The lower the value, the more similar are the images. For example, the value »0« would mean identical images. DeepAI offers APIs for Javascript, Python, Ruby, and Csharp, as well as examples that help you set up the APIs. Alternatively, you can use the tool directly from the website by uploading both images, but this process is rather time-consuming. In summary, this tool can be very effectively used to find contextually similar images and to group them based on their contents.


  • Great API for several programming languages
  • Best for grouping images


  • Lacks additional options

2. SuperAI


The image similarity tool by Super AI compares two images and returns a score between 0 and 1 that indicates how similar they are. Value 1 means that images are identical, while 0 means they are completely different. You can then use these results to train machine learning algorithms, automatically identify duplicate content, and even perform reverse image searches. The algorithm does not only compare colours and shapes. It can also recognise faces and facial expressions. For example, it will recognise the same person in two completely different images.


  • The advanced algorithm recognises people
  • Very easy to use


  • Feature-poor
  •  No API
  •  Lacks additional instructions

1. How to find the difference between two pictures for free?

To find the difference between two pictures for free, you can use a number of online tools that find differences between two pictures. Simply upload two or more photos, and let the tool crunch the numbers. The resulting diff image shows all the differences between the two pictures.

2. How are AI diff checkers used in the real world?

A lot of online businesses and eCommerce stores use diff checkers to recommend products with similar product images. This one simple feature can more than double conversion rates. Diff checkers are also used by stock photo agencies to find how their clients use stock photos.


In the future, I expect AI to even further improve and find its uses in other fields. However, AI is not a silver lining for every problem. First of all, it is quite difficult to efficiently code for some problems. Secondly, we do not get any insight into its results. Therefore, it is referred to as a »black box«.

Regardless, I believe that AI will become a part of virtually every software thanks to its wide applicability and great potential. It is inevitable that AI will also improve image diff and image recognition even further by working even faster and more accurately as it becomes more and more complex.
