What is a diff checker?

A diff checker compares two pieces of text and highlights the differences between them. It shows what was added, removed, or unchanged.

What diff modes are available?

This tool supports character-level, word-level, and line-level diff comparison. Line mode is best for code, while word mode works better for prose.

Is my data safe?
