How does text diff work?

The algorithm compares texts line by line, identifying additions, deletions, and modifications with color highlights.

Unified vs split view?

Unified shows changes inline. Split shows original and modified side by side.

Yes. It preserves whitespace and indentation, suitable for source code comparison.

What algorithm is used for text comparison?

Most diff tools use variations of the Myers diff algorithm or the longest common subsequence (LCS) algorithm. These efficiently identify the minimum set of changes between two text sequences.

Can I compare two files for differences using this tool?

Yes. Paste the contents of both files into the left and right panels. The tool highlights additions in green and deletions in red, showing exactly what changed between the two versions.
