Step 2:

In the search box, type your prompt for comparison. For this example, we used "Compare these 2 documents” and hit the “Enter” key on your keyboard. ChatGPT will now analyze your documents and provide detailed analytics about their similarities and differences.

Next up on the list is Idox.ai, which combines a good graphical user interface with powerful AI processing capabilities. This platform is designed for verifying, protecting, and comparing official documents. When comparing documents, it will give a side-by-side view with synced scrolling for a comprehensive experience.

It highlights changes when you click them from the list of all changes located on the right side of the interface. Moreover, these changes are color-coded so that you can easily tell which change indicates deletion, insertion, or text replacement.

Step 1:

Go to the website on your browser and click “Compare." Move your cursor to the "File” button and choose the source location. For example, we selected “My Local Drive" to upload a file from offline storage. Select a file from the file explorer window and click "Open" to upload it. Repeat the step for the second file. After both files are uploaded, click "Compare."

Step 2:

Idox.ai will display the two files side-by-side with their differences "Highlighted”. You can click any listed change from the "Right Menu" to highlight the documents.

When using Copyleaks to compare two documents, you can paste text, paste ink, or upload the file itself. When comparing your files, you get a side-by-side view of the text.

However, the text appears to have multiple errors in the Copyleaks interface. Moreover, its user interface could be better designed. Instead of highlighting differences, it highlights the same content, which reduces comparison efficiency.

Step 1:

Open the Copyleaks AI Document Comparison website on your computer's browser. From the top, select "Files” to upload files from offline storage since “Text" is selected by default, where you need to paste text, which is not very convenient.

Step 2:

Copyleaks will display both documents in a side-by-side view. It will highlight their changes with a window on the top right showing statistics.

Part 4. Problems to Compare Two Documents with AI.

With the three best AI tools discussed in the article above, you may encounter multiple problems when comparing your documents.

Comparison display

The first problem is the user interface. When comparing two documents, you either need a side-by-side comparison or a content overlay comparison. Tools like ChatGPT only list changes, making locating the differences difficult.

Highlighting Changes

AI tools like Idox do not provide a filter option when comparing documents. Having the option to choose between text, graphics, and other document elements makes the comparison more effective.

Security Concerns

Uploading your confidential documents to online tools raises security concerns. However, using an offline tool for the comparison is not a problem.

Internet Dependency

Using AI tools requires a consistent and stable internet connection. Without an internet connection, you cannot efficiently compare your documents.
