Text diff (difference) is a method of showing the changes between two versions of a text document. It highlights additions, deletions, and modifications, making it easy to see exactly what changed between versions. This is fundamental to version control systems and collaborative editing.
Diff algorithms analyze two text inputs and identify the differences using sophisticated pattern matching techniques. The result shows exactly what was added, removed, or changed, often with context lines to help understand the changes.
Compares entire lines of text. Best for structured documents and code files.
Compares individual words. Useful for prose and documents with frequent small changes.
Most detailed comparison. Shows every character change, ideal for precise editing.
