FAQ Frequently Asked Questions

Can I compare documents longer than a few pages?
Yes, the tool can handle large documents efficiently. While there is no strict limit, very large files (over 50,000 words) may take longer to process. For best performance, consider breaking extremely large documents into sections.
What types of changes does it highlight?
The tool highlights additions (green), deletions (red), and modifications (yellow/orange). It can detect word-level changes, moved paragraphs, and formatting differences. You can choose between character-level and word-level comparison granularity.
Can I export the comparison results?
Yes, you can export the highlighted comparison in various formats including HTML, PDF, or plain text. This is useful for sharing review results with colleagues or keeping records of document changes.
How does it handle formatting differences?
The tool focuses on text content differences rather than formatting like bold, italic, or font changes. This makes it ideal for comparing the actual content of documents regardless of how they are styled.
Is this suitable for comparing code files?
Yes, the tool works well for comparing code files, configuration files, and other structured text. It can highlight syntax changes, added functions, and modified variables, making it useful for code review processes.
