Frequently Asked Questions
How do I compare two text files online?
Paste your original text in the left box and the new text in the right box, then click 'Compare Texts'. The tool will highlight differences with red for removed text and green for added text.
What is a diff checker used for?
A diff checker compares two versions of text to find differences. It's commonly used for code review, document revision tracking, comparing configuration files, and verifying content changes between versions.
Can I compare code with this diff tool?
Yes, our text diff tool works with any text including code in any programming language. It compares text word-by-word and highlights all changes, making it useful for code review and debugging.
Does the diff checker work offline?
Our diff comparison runs entirely in your browser - your text is never sent to a server. This means it works with any text you paste, and your content remains private and secure.
How accurate is the text comparison?
Our tool uses an LCS (Longest Common Subsequence) algorithm to accurately detect insertions, deletions, and unchanged text. It compares word-by-word for readable results while maintaining precision.
