Frequently Asked Questions
How does the text comparison algorithm work?
Our diff checker uses advanced algorithms to identify insertions, deletions, and modifications at both character and word levels. It provides instant visual feedback with color-coded highlighting: green for additions and red for deletions.

Yes, our online text comparison tool is completely free with no hidden costs. You can compare unlimited texts without any restrictions, sign-ups, or payment requirements.
Can I compare code files and programming scripts?
Absolutely! Our diff tool is perfect for comparing source code, configuration files, JSON, XML, and any text-based programming files. Use the monospace font option for better code readability.
What's the maximum text length I can compare?
