Diffchecker is a desktop-based document comparison and redlining application built for legal teams that handle confidential contracts, agreements, and other sensitive materials. The tool runs fully offline, meaning files are processed locally and do not pass through external servers, making it suited to compliance-sensitive workflows.
Key features and functions include:
Cross-Format Document Comparison
Supports comparison of PDF to Word, PDF to PDF, and Word to Word documents, with changes identified at both the word and character level. The tool also detects formatting changes including font size, style, and color, as well as moved text.
Legal Redlining
Generates redlines in Word and PDF formats, with customization options to align output with firm-specific preferences. Redline exports include a revisions report summarizing all identified changes.
Offline Operation and Data Privacy
The desktop application functions without an internet connection. No user data is collected through the desktop app and no client data is stored on the vendor's servers.
iManage Integration
The Legal plan connects directly with iManage Cloud, allowing users to open documents from iManage, run comparisons in the desktop application, and save results back to iManage without file transfers through external systems.
OCR for Scanned Documents
An integrated OCR engine enables comparison of scanned documents, images, and presentations that are not natively text-based.
Bulk Document Review
Supports comparison across large volumes of files, enabling teams to identify modified documents across folders and track changes across multiple document versions simultaneously.
Excel and Spreadsheet Comparison
In addition to Word and PDF formats, the tool supports comparison of Excel files and other data formats to identify changes in spreadsheets and tables.
