Document Comparison lets you upload or select two documents and view a detailed diff of their content. Use it to review contract revisions, track policy changes, or verify document updates.
Starting a comparison
- Navigate to Knowledge > Documents.
- Open the comparison dialog from the action menu.
- Select two documents:
| Side | Label | Options |
|---|
| Left | Base document | Upload a file or select an existing document |
| Right | Comparison document | Upload a file or select an existing document |
- Upload — drag and drop or browse to upload a file from your device.
- Existing — search and select from documents already in your knowledge base.
- Click Compare. The platform sends both documents to the RAG service for analysis.
Supported file types
PDF, DOCX, XLSX, CSV, TXT, PPTX, and common image formats.
Reading the results
The comparison results show a summary bar and a list of change blocks.
