Question 1

What is the difference between line and word diff?

Accepted Answer

Line-by-line mode compares documents one line at a time, showing entire lines as added, removed, or unchanged. Word-by-word mode compares at the word level, highlighting individual word changes within lines for more granular results.

Question 2

How are changes highlighted?

Accepted Answer

Added content is highlighted in green, removed content in red, and unchanged content has no highlight. Line numbers are shown in the gutter for easy reference.

Question 3

Can I compare large documents?

Accepted Answer

Yes. The diff algorithm runs efficiently in your browser and handles documents of any reasonable size. Very large documents (tens of thousands of lines) may take a moment to compute.

Question 4

What format do the input documents need to be in?

Accepted Answer

The tool compares plain text, so it works with any Markdown, code, or plain text content. You do not need to use valid Markdown -- any two text documents can be compared.

Question 5

Is my data sent to a server?

Accepted Answer

No. The diff computation happens entirely in your browser. Neither the original nor modified document is ever transmitted to any server.
