About This Tool


Text comparison is essential for reviewing changes, checking versions, and ensuring accuracy. Our diff tool highlights exactly what changed between two texts, making it easy to spot additions, deletions, and modifications.

The side-by-side view shows both texts with differences color-coded: green for additions, red for deletions, and yellow for modifications. This visual approach makes reviewing changes quick and intuitive.

Choose between line-by-line comparison for structured content like code, or word-level comparison for prose and documents. Word-level diff catches small changes within lines that line-level comparison might group together.

The ignore whitespace option helps focus on meaningful changes by overlooking differences in spacing or indentation. Similarly, ignore case treats differences in capitalization as non-changes when enabled.

FAQ

What do the colors mean?
Green indicates additions (text in the new version only), red shows deletions (text in the old version only), and yellow marks modifications.
Can it compare code?
Yes, the tool works great for comparing code. The line-by-line mode is particularly suited for code review.
Does it detect moved text?
The tool shows where text was removed and where it was added. It doesn't explicitly track if the same text was moved.
Is there a size limit?
The tool handles reasonably large texts, but very large documents may be slow. For huge files, consider specialized diff software.
Can I compare files directly?
Currently, you paste text into the tool. For file comparison, open files in a text editor and copy content.
