About Line Diff & Compare
Line Diff & Compare compares two texts line by line and shows which lines were added, removed, or unchanged. This is the most common view for comparing code, logs, or lists.
View the result side-by-side or in a Git-style unified format. The similarity percentage gives a quick sense of how close the two inputs are.
FAQ
What is the difference between "diff" and "compare"?
Both are done by the same tool. "Diff" highlights the lines/parts that changed (added/removed), while "compare" shows how similar the two inputs are (similarity percentage + summary). You get both at once here.
Is my data sent to a server?
No. The entire comparison is computed in your browser with JavaScript. Nothing is uploaded, logged, or stored on our servers — safe for sensitive data.
