Comparing Documents

Instantly compare two documents with AI-powered change detection.

Compare gives you an instant, AI-powered comparison between two documents. Upload an original and a modified version, and Irys highlights every difference with a natural-language summary and detailed redline.

Starting a comparison

1

Open Compare

Navigate to Compare from the left sidebar.

2

Upload the Original document

Drag and drop a file into the Original panel on the left, or click Browse Library to select a document you have already uploaded.

3

Upload the Modified document

Drag and drop a file into the Modified panel on the right, or browse the Library.

4

Run the comparison

Click Compare and Irys processes both documents, identifies differences, and generates results.

Compare supports .docx format for document comparison.

AI Change Summary

Once the comparison completes, Irys generates an AI Change Summary at the top of the results. This includes:

• A natural-language description of the differences between the two documents — what was added, removed, and modified, explained in plain English.

• Recommendations highlighting changes that may need attention, such as altered obligations, shifted deadlines, or removed protections.

The summary gives you immediate context before you dive into the line-by-line details.

Stats bar

Below the summary, a stats bar shows word-level metrics:

Metric	Description
Words added	Number and percentage of new words in the modified document.
Words removed	Number and percentage of words deleted from the original.
Words unchanged	Number and percentage of words that remain the same.

This gives you a quick sense of how much has changed between the two versions.

View modes

Toggle between two view modes to review changes:

Side by Side

Both documents are displayed in parallel panels with synchronized scrolling. Differences are highlighted in each panel so you can see exactly what changed and where.

Redline

A single-document view with inline markup showing additions, deletions, and modifications. This is the traditional legal redline format — added text is marked, removed text is struck through, and you can read through the document as a single narrative.

Exporting the redline

Export your comparison results to share with colleagues or include in your records. Click Export to download the redline view as a document.

Comparison history

Previous comparisons are saved so you can return to them later. Access your comparison history from the Compare page to re-open past results without re-uploading documents.
